6.2 Functional tests
The person is located at a distance corresponding to the maximum operating range of the detector.
To get the effect of lateral movement of a standard target (human) relative to the detector, it is necessary to ensure either the movement of the target relative to the fixed detector, or the rotation of the detector relative to the fixed target. In this case, the detector must be rotated at a speed equivalent to a transverse travel speed of 0.3 m/s (0.1 m/s - for open area detectors).
An alarm notification should be issued when the detector is rotated by an amount equivalent to the movement of the target at a distance of up to 3 m.
6.2.1.3 Tests for and must be repeated with the standard target placed at a distance corresponding to the minimum range of the detector.
Tests at and must be repeated when placing a person at a distance corresponding to the minimum operating range of the detector (at )
6.2.1.4 During the tests, either the movement of the target relative to the detector, or the rotation of the detector relative to the target located at three randomly selected points of the detection zone, must be ensured. At each of the selected points, the test is repeated for .
6.2.2 Time to restore the detector to standby mode
After the tests, the distance traveled by the target is recorded until the moment the detector issues an alarm notification. The standard target is then returned to its original position.
After that, the movement of a person or another object that is different from the standard target begins, until the detector issues an alarm notification. After that, the movement stops. The test must be repeated after 10 s.
In this case, the distance traveled by the target before the detector issues an alarm notification should not differ from the value obtained in the first part of these tests by more than 10%.
(Revised edition, Rev. No. 2).
6.2.3 Resistance to secondary target movement
For testing purposes, the conditions for should be reproduced, except that the secondary standard target is used as the standard target. The secondary target should be installed at a height of no more than 100 mm from the floor, and its main axis is located tangentially to the detector (perpendicular to ECHZ) and parallel to the floor. The position of the target must be chosen taking into account the location of the elementary sensitive zones of the detector, at which the maximum effect is achieved (and when moving must cross elementary sensitive zones).
To obtain the effect of transverse movement of the secondary target relative to the detector, it must move, or the detector must rotate. When moving, a transverse speed equal to 1 m / s should occur.
(about penetration).
(Revised edition, Rev. No. 2).
6.2.4 Tolerance to changes in background temperatures
The detector must be installed in front of the screen, which ensures the creation of a temperature background, the temperature of the screen must be 25 °C. The temperature difference across the screen surface should not exceed 0.5 °C. During the test, the temperature of the detector remains constant.
The background temperature is raised at a rate of 1 °C/min (5 °С/min - for open area detectors) until it reaches 40°C.
During the test, the detector should not give an alarm notification. (about penetration).
An increase in the background temperature within one elementary sensitive zone can serve as an imitation of this test. In this case, the change in the radiant flux at the detector aperture should be the same as in full-scale tests.
Set the detector supply voltage to 15 +2 % below its nominal value and determine the sensitivity of the detector in accordance with .
Perform a similar procedure when the detector supply voltage is increased by 25 -2 % relative to its nominal value.

An additional secondary standard target should be installed no more than 100 mm from the floor. Target position - 0.5 m horizontally from the detector projection on the floor. The tests are repeated several times, each time increasing the distance from the detector projection to the secondary standard target by 0.5 m up to the detector's maximum range.
To obtain the effect of transverse movement of an additional secondary standard target relative to the detector, it is necessary to ensure either the movement of the target relative to the fixed detector, or the rotation of the detector relative to the fixed target. In this case, the detector must rotate at a speed equivalent to the transverse travel speed equal to (1.0 ± 0.1) m/s.

Installation of technical means of security systems should be carried out using small-scale mechanization, mechanized and electrified tools and devices that reduce the use of manual labor.
Installation of security detectors
The choice of types of security detectors, their number, determination of installation locations and installation methods should be determined in accordance with the requirements of the current regulatory documents, the type and significance of the protected object, the adopted security tactics, the object interference situation, the size and design of the blocked elements, the technical characteristics of the detectors. In this case, the formation of invisible (“dead”) zones should be excluded.
Magnetic contact detectors are designed to block the opening of doors, windows, hatches, shop windows and other movable structures. They are installed, as a rule, in the upper part of the blocked element, from the side of the protected premises at a distance of 200 mm from the vertical or horizontal (depending on the type of magnetic contact detector) solution line of the blocked element. In this case, the reed switch of the detectors is preferably installed on the fixed part of the structure (plinth, door frame), and the magnet - on the movable part (door, window frame). When blocked internal doors magnetic contact detectors, depending on the type, must be installed on the inside of the doors, and, if necessary, on both sides with the inclusion of detectors in different alarm loops.
Travel limit switches are designed to block the opening of building structures with significant mass and linear dimensions (gates, loading and unloading hatches, etc.). Switches should be installed on the most massive parts of the interlocked structure on brackets. The enclosures or bases of the switches must be earthed. Mounting switches on grounded metal panels does not relieve the need to connect a ground wire.
Surface shock-contact detectors are designed to block glazed structures located no closer than 5 m from the carriageway of the street. The detectors should be installed from the side of the protected premises. The locations of the component parts of the detectors are determined by the number, mutual arrangement and the area of blocked glass cloths. The detectors are attached to the surface of the glass sheet with glue.
Blocking of glazed structures with aluminum foil is carried out in the presence of vibration or vehicle interference at the protected facility. The foil should be glued around the perimeter of the glass sheet to be blocked on the inside of the piping using oil paint, varnish or primer. Foil blocking should provide protection for structures both from glass breakage and from glass being removed from the piping (or turning in the piping) without breaking.
When blocking openings made of profiled glass or glass blocks, the foil should be glued through the middle of the glass block parallel to the contour lines of the opening with a step of no more than 200 mm. Gluing the foil to the glass surface should be carried out at positive ambient temperatures. The connection of the foil with the signaling loop should be carried out with flexible conductors.
After gluing the foil, paint must be applied to it, while the paint strip must protrude beyond the edges of the foil by at least 3 mm. U-shaped foil sticker (only the top and sides of the strapping) is not allowed. After completing all installation work on sticking the foil on the glazed structures, check its integrity with an ohmmeter.
When blocking non-capital building structures “for a break”, a PEL, PEV or similar wire with a diameter of 0.18 ... 0.25 mm should be laid on the inside of the structures over the entire area parallel to the contour lines and fastened with brackets with a fastening pitch of 200 mm. The distance between the long sides of the blocking wire for open or hidden laying should be no more than 200 mm.
With an open laying method, the wire must be silenced from mechanical damage with plywood, hardboard, plasterboard or other similar materials.
With a hidden laying method, the wire must be laid in strobes, followed by their sealing with adhesive putty and painting. The depth and width of the strobe must be at least two diameters of the wire being laid.
Barred openings should be blocked by double wrapping the pre-painted horizontal and vertical bars of the grille flexible wire to eliminate the possibility of shorting blocked sections.
Layed wires must repeat the configuration of the grid. After blocking, the wires and the grille are painted again.
The transition of the wire from one lattice rod to another should be carried out by tying the frame in a hidden way.
Installation of capacitive, radio wave, ultrasonic, optoelectronic and combined detectors should be carried out on rigid, vibration-resistant supports (solid walls,
columns, poles, etc.) using brackets or special stands and exclude the possibility of false triggering of detectors for this reason.
In the protected area, as well as near it at the distances specified in the technical documentation, there should be no foreign objects that change the sensitivity zone of the detectors. When installing several radio wave detectors in one room, it is necessary to use detectors with different frequency letters.
Installation of surface piezoelectric detectors designed to block ceilings, floors and walls of premises from a breach is carried out in places protected from mechanical damage and access by unauthorized persons at the rate of 75 ... 100% coverage of the protected area.
When installing detectors that block window and door openings in a wooden frame, their hidden installation should be used, as a rule (in strictly justified cases, deviations from this rule are allowed).
Installation of fire detectors
Placement and installation of automatic heat, smoke, light and manual fire detectors must be carried out in accordance with the project, the requirements of NPB 88-2001 *, technological maps and instructions.
The number of automatic fire detectors is determined by the need to detect fires throughout the controlled area of the premises (zones).
If the fire alarm system is designed to control automatic settings extinguishing, smoke removal and fire warning, then in order to form a control command in the protected room or zone, there must be:
at least three fire detectors when they are included in the loops of two-threshold devices or in addressable loops, or in three independent radial plume single-threshold devices;
four fire detectors when they are included in two loops of single-threshold devices, two detectors in each loop.
Smoke and heat detectors should be installed, as a rule, on the ceiling.
If it is impossible to install detectors on the ceiling, they can be installed on walls, beams, columns. It is also allowed to suspend detectors on cables under the ceilings of buildings with light, aeration, antiaircraft lamps. In these cases, the detectors must be placed at a distance of no more than 300 mm from the ceiling (including dimensions detector).
Smoke and heat fire detectors should be installed in each compartment of the ceiling, limited by building structures (beams, girders, plate ribs, etc.) protruding from the ceiling by 0.4 m or more. If there are protruding parts on the ceiling from 0.08 to 0.4 m, the area controlled by the detector is reduced by 25%.
If there are boxes on the ceiling in the controlled room, technological platforms with a width of 0.75 m or more, having a solid structure and spaced at a lower mark from the ceiling at a distance of more than 0.4 m, it is necessary to additionally install fire detectors under them.
Automatic fire detectors must be installed in each compartment of the room formed by stacks of materials, racks, equipment and building structures, the upper edges of which are 0.6 m or less from the ceiling.
Automatic fire detectors of one fire alarm loop should control no more than five adjacent or isolated rooms located on the same floor and having exits to a common corridor (room).
With automatic fire detectors of one fire alarm loop, it is allowed to control up to 10 in public, residential and auxiliary buildings, and with a remote light alarm from automatic fire detectors and installed above the entrance to the controlled room - up to 20 adjacent or isolated rooms located on the same floor and having exits to the common corridor (room).
The number of automatic fire detectors included in one fire alarm loop is determined by the technical characteristics of the receiving and control equipment.
Installation of control panels, signaling and starting devices and annunciators
The requirements of RD 78.36.003-2002, RD 78.145-93, NPB 88-2001* must be taken into account when placing control panel devices, control panels and other technical means of security systems (hereinafter referred to as devices).
Installation of devices of small information capacity (up to five alarm loops) should be carried out:
in the presence of a specially allocated room - at a height convenient for maintenance;
in the absence of a specially allocated room - at a height of at least 2.2 m.
Installation of devices in places accessible to unauthorized persons, for example in trading floors trade enterprises, should be carried out in lockable cabinets, the design of which does not affect the performance of the devices.
If, according to fire safety requirements, it is not allowed to install devices directly in a room equipped with signaling devices, then they are installed outside the room in lockable metal cabinets or boxes that are blocked for opening.
Installation of devices of medium and large information capacity should be carried out in dedicated rooms: on a table, wall or a special design, at a height convenient for maintenance, but no less! m from floor level.
It is not allowed to install devices:
- in combustible cabinets, at a distance of less than 1 m from heating systems;
explosive premises;
dusty and especially damp rooms, as well as those containing vapors of acids and corrosive gases.
Placement of fire control panels at facilities without personnel on round-the-clock duty
Objects that do not have round-the-clock stay of duty personnel on their territory in Russia a large number of, and in the regulatory framework, this situation in the context of the placement of fire control panels (FACP) is described, in our opinion, not unambiguously. But it is the PPKP that is the heart and brain of the entire system. The convenience and transparency of the functioning of the entire fire alarm system depends on its correct placement. It is noteworthy that the possibility of the absence of personnel on duty at the facility around the clock was considered in the recently adopted amendments to SP 5.13130.2009 (SP5). In accordance with the order of the Ministry of Emergency Situations of Russia dated 06/01/2011 No. No. 274, in paragraph 13.14.4 of SP 5, a whole paragraph appeared on this topic: “... In the absence of personnel on duty at the facility, fire notifications should be transmitted to the fire departments via a radio channel allocated in the established order or other communication lines in automatic mode.... ". Obviously, we will talk about small objects, such as schools, or office buildings, often with several tenants, etc.
Paragraph 13.14.5 of SP 5 reads: “ Control and reception devices and control devices, as a rule, should be installed in a room with a round-the-clock stay of personnel on duty. In justified cases, it is allowed to install these devices in rooms without personnel on round-the-clock duty, while ensuring separate transmission of notifications about a fire, malfunction, condition of technical equipment to a room with personnel on round-the-clock duty, and ensuring control of channels for transmitting notifications. In this case, the room where the devices are installed must be equipped with a security and fire alarm and protected from unauthorized access.”.
The last suggestion gives the designers the idea to hide the control panel in some closet, locked and equipped with burglar alarm sensors. However, this often goes against common sense, for such facilities as, for example, small schools, shops, where there are on-duty personnel at the facility during working hours. In this case, it is advisable to mark the control panel in the room in which the latter was in full view of the duty personnel in order to control its performance. However, what about the requirement "... In this case, the room where the devices are installed must be equipped with a security and fire alarm and protected from unauthorized access."? The current practice of clarifying disputed issues at VNIIPO with the help of letters provides some food for thought on this matter. Curious is the letter, which indicates that protection against opening and unauthorized access in the device is an alternative to a security alarm and does not contradict the requirement of clause 12.48 of the then main document NPB 88-2001 *, regulating the placement of the control panel. At the moment, almost all control panels have a built-in tamper sensor. In addition, the requirement to have protection of the controls of the control panel from unauthorized access by unauthorized persons is mandatory in accordance with subparagraph d of clause 7.2.1.1 of GOST R 53325-2009.
Such, at first glance, a harmless question, as the height of the installation of the control panel, is also not obvious. In accordance with paragraph 1 of Article 151 of the Law of July 22, 2008 No. 123-FZ (Technical Regulations), from the date of its entry into force until the date of entry into force of the relevant technical regulations, the requirements for objects of protection established by regulatory legal acts of the Russian Federation and regulatory documents of federal executive bodies, including the above-mentioned ones, are subject to mandatory execution to the extent that they do not contradict the requirements of this Federal Law. Therefore, we use the provisions of SP 5, as well as all the remaining ones that do not contradict the latter.
At present, the installation height of receiving and control devices in the field of fire safety is regulated by several conflicting documents in Table. 2:

|
|
SP 5.13130.2009 clause 13.14.9. |

|
When analyzing the above height requirements, it is clear that their simultaneous fulfillment is impossible when using a control panel that combines a control and indication device, which is typical for small objects. Moreover, in RD 78.145-93 and the "Manual" to RD 78.145-93 we are talking about the height of the installation of the device, in NPB 88-2001 * - about the height to the operational controls, and in SP 5.13130.2009 - about the height to the operational controls and indications. It is possible to trace the trend of specification of height requirements: the height of the instrument placement - the height to the controls - the height to the controls and indications. What is noteworthy, for our case, RD 78.145-93 and "Manual" to RD 78.145-93, in the absence of a specially allocated room, devices of small capacity must be placed at a height of at least 2.2 m, and devices of medium and large information capacity - at a height convenient for service, but not less than 1 m from the floor level (RD 78.145), and at a height of not less than 1.5 m from the floor level, the “Manual” to RD 78.145 explains to us. Obviously, the placement of the device at a height of 2.2 m was done for reasons of restricting unauthorized access to it.
Here is an explanation from VNIIPO regarding the height of the location of the control panel: “ Priority in application is given to the provisions of regulatory documents of a later release ... the provisions of NPB 88-2001 * took precedence in relation to RD 78.145 (1993) and the "Manual" to RD 78.145. The provisions of RD 78.145 (1993) and the Guidelines for RD 78.145 are mostly related to burglar alarms. The provisions of NPB 88-2001 * directly relate to fire automatics. It should also be taken into account that the provisions of clause 12.52 of NPB 88-2001 * on the placement of devices are consistent with the requirements of clause 9.1.1, trans. 8) NPB 75-98 on the presence of mandatory protection of the controls of the control panel from unauthorized access by unauthorized persons. At present, the requirements of the Federal Law of July 22, 2008 No. 123-FZ "Technical Regulations on Fire Safety Requirements" should be complied with and the provisions of SP 5.13130.2009 should be used.
Therefore, it remains to find out the ergonomic requirements for the placement of operational controls and indications and figure out how they correspond to the requirement that controls be located at a height of 0.8–1.5 m.
Workplaces differ depending on the position in which the activity is carried out - sitting or standing. The requirements for the location of controls and information display facilities are given in Table 3 for the case of emergency controls and rarely used information display facilities (rarely - no more than two operations in 1 hour) for men and women.
Table 3

When performing work sitting in accordance with GOST 12.2.032-78 |
When performing work while standing in accordance with GOST 12.2.033-78 |

|
|
Placement of information display facilities |
can be placed in a vertical plane at an angle of ±60° from the normal line of sight |
the average height of the information display means for men and women should be 1365 mm |
It can be seen that the location of the controls at a height of 0.8–1.5 m fits into the requirements only when performing work while standing, and rather resembles the intersection of the requirements for performing work while sitting and standing.
As a generalization of the above, if there are on-duty personnel at the facility during working hours, it is advisable to install the control panel in rooms convenient for its control, using the built-in protection of the device for opening and using the possibility of protecting the control panel from unauthorized access to the controls as an alternative to the security alarm in the room. The control panel should be placed in accordance with the requirements set out in Table 2, however, when organizing a standing workplace, the controls should be placed at a height of 0.8–1.5 m.

FGU VNIIPO EMERCOM of Russia. Letter dated 29.10.2009. No. 12-4-02-5100. On the application of the provisions of regulatory documents for installation.
Light and sound annunciators, as a rule, should be installed in places convenient for visual and sound control (inter-window and inter-showcase spaces, exit door vestibules).
It is allowed to install a sound annunciator on the outer facade of a building in a metal casing or a special version at a height of at least 2.5 m from the ground level.
If there are several control panels at the facility, the control panel, the light annunciator is connected to each device, and the sound annunciator can be made common.
Installation of other technical means of security systems is carried out in accordance with the project documentation, the requirements of regulatory and technical documents and the technical
product documentation.
Alarm installation
The alarm system must be made "without the right to turn off" and displayed on the internal security console of the facility or directly on the monitoring station of private security or on duty at the internal affairs body.
The choice of the method of switching on and installation locations of hand and foot alarm devices is determined by the conditions for ensuring maximum safety and ease of use, while the installation sites must be hidden from observation by unauthorized persons.
For the same purposes, mobile alarm devices operating via a radio channel (radio buttons, radio key fobs) are used.
It is forbidden to install magnetic contact alarms in close proximity (less than 200 mm) to sources of magnetic fields and large masses of ferromagnetic materials.
Installation of technical means of perimeter security and television
Technical means for protecting the perimeter and territory of the facility must provide:
- predetermined security mode;
reliability in operation and the absence of false alarms from the effects of meteorological factors and other interference;
the impossibility of overcoming the security system;
simultaneous reception of alarm signals from any blocked area with determination of the place of violation.
To protect the perimeter and territory of the facility, the following should be used: technical means of detection for the perimeter, means and systems for access control and management, security lighting, sound annunciators, and, if necessary, security television systems, radio and telephone communications.
It is also recommended to include technical devices for graphic display of the perimeter of the object (computer, light panel with a mnemonic diagram of the protected perimeter) in the technical means of protecting the perimeter, which should be located in the security room.
To control the passage of workers and employees, as well as the passage of vehicles to the protected area of the facility, depending on the number of employees and the regime of the facility, turnstiles or other automated blocking devices should be used. Placement and installation of automated access control devices at the facility must ensure compliance with the requirements of SNiP 2.01.02-85.
Perimeter security means can be placed on the main fence, building, structure or in the exclusion zone.
Security detectors must be installed on solid foundations, special poles or racks, ensuring the absence of vibrations and vibrations. The perimeter of the territory (with gates and wickets included in it) must be divided into protected areas (zones) with their connection to the receiving equipment by separate loops. The length of the section is determined based on the tactics of protection, specifications equipment, external barrier configuration, line-of-sight conditions and terrain, but not more than 200 m for technical operation and prompt response.
When installing the means of protecting the perimeter of objects, the following should be taken into account: types of alleged threats, interference conditions, terrain, length and engineering and technical
the strength of the perimeter, the type of fencing, the presence of transport routes along the perimeter, the exclusion zone and its width.
Power wires and signal cables to the technical means of perimeter security systems should, as a rule, be laid in a hidden way.
Technical means of closed-circuit television should be placed around the perimeter in accordance with the working drawings of the project. When placing cameras, the following conditions must be met:
- television cameras are placed around the perimeter within the line of sight of the observed area of the perimeter of the object and the neighboring camera so that direct illumination of an extraneous light source (sun, perimeter illumination, etc.) does not fall into the field of view of their lenses;
there should be no large magnetic masses and strong sources of electromagnetic fields near the camera;
to television cameras and other devices of the transmitting side, free and safe access to service personnel should be provided.
The receiving part of CCTV systems is located in the security room in accordance with the design documentation in compliance with the requirements of the manufacturer's technical documentation. The security lighting network along the perimeter should be carried out separately from the outdoor lighting network and divided into independent sections.
Security lighting should provide:
- the necessary uniform illumination of the perimeter (rejection zone) with the expectation that the light points from the lamps overlap and form a continuous strip 3 ... 4 m wide;
possibility automatic start lighting in one area or the entire perimeter when an alarm is triggered;
the ability to control lighting - the inclusion of any area or the entire perimeter.
Security lighting fixtures should be installed in close proximity to the fence line inside the territory in places that are convenient and safe for maintenance.
Calls, howlers, sirens, amplifiers, loudspeakers should be used to transmit powerful sound signals when the technical means of perimeter security systems are triggered.
Horn loudspeakers should be used to ensure directionality of commands.
The equipment of radio notification and telephone communication devices must be installed according to the location and bindings specified in the project.
The electrical wiring of the linear part of the technical facilities along the perimeter is a complex consisting of cable lines and electrical wires, connecting and connecting devices, metal structures and ducts laid and fixed on the elements of the fence, buildings and structures, devices for their fastening and protection against mechanical damage. Installation of the linear part must be carried out in accordance with the project and taking into account the requirements of Ch. 2.1, 2.3 PUE, SNiP 3.05.07-85, RD 78.145-93, VSN-600-81 "Instruction for the installation of structures and devices for communication, broadcasting and television."
All equipment that is part of the perimeter security system must be tamper-evident.
Installation of electrical wiring of the linear part of the alarm
Alarm loops, trunk and distribution networks are made of wires and cables specified in the project (inspection report). It is allowed, in agreement with the customer and the relevant organizations, to use for this purpose the communication lines of the GTS, departmental communication lines at the facility and existing integrated networks.
With open parallel laying of wires or cables for signaling and electrical wiring, power supply and lighting, the distance between them must be at least 0.5 m. Wiring routes must be chosen as short as possible, taking into account the location of electric lighting, radio transmission networks, water and gas mains, as well as other communications.
On the walls inside protected buildings, wires and cables should be laid at a distance of at least 0.1 m from the ceiling and, as a rule, at a height of at least 2.2 m from the floor. When laying wires and cables at a height of less than 2.2 m from the floor, their protection against mechanical damage should be provided.
The laying of the wires of the alarm loops connected to the detectors is carried out covertly and openly in accordance with the project (survey report).
Electrical wiring passing along external walls at a height of less than 2.5 m or through rooms that were not subject to protection must be made in a hidden way or in metal pipes.
When crossing power and lighting networks, cables and signaling wires must be protected by rubber or PVC tubes, the ends of which should protrude 4 ... 5 mm from each side of the transition. When crossing, cables of a larger capacity should lie against the wall, and cables of a smaller capacity should bend around them from above. Cables of smaller capacity may be passed under cables of larger capacity when laying them in strobes.
Depending on the length of the parallel laying of signaling circuits and the radio broadcasting network, the distances between them must be at least: 50 mm with a parallel laying length of 70 m; 30 mm with a length of up to 50 m; 25 mm with a length of up to 30 m; 20 mm with a length of up to 20 m; 15 mm with a length of up to 10 m; less than 15 mm with a parallel laying length of up to 7 m.
It is not allowed to lay distribution cables with a capacity of more than 100 pairs along the walls.
In the case of hidden wiring in the floor and floors, the cables must be laid in channels and pipes. Seal of cables in building structures tightly is not allowed. An act is drawn up for laying hidden wiring. In places of a turn at an angle of 90 ° (or close to it), the bending radius of the laid cables must be at least seven cable diameters.
Cables and wires must be fastened to building structures using scrapers or staples made of thin-sheet galvanized steel, polyethylene elastic staples. Fasteners should be installed using screws or glue.
The wires from the detectors should be fastened:
- - steel nails, provided that the diameter of the nail head is not greater than the distance between the cores of the wire (for wires with a separate base type TRV, TRP);
- with brackets, in the places where the wire is attached, an uncut PVC tube with a length of at least 10 mm should be placed under the brackets (for wires without a dividing base of the NVM, PMVG, PKSV types).
The fastening step for horizontal laying is 0.25 m, for vertical - 0.35 m. Splicing and branching of wires of TRP, TRV (and similar) brands should be done in boxes by soldering or screwed.
Several wires laid along the same route can be placed close to each other. Nails and staples securing the wire are placed in a checkerboard or sequential order (mutually shifted along the length of the wire by 20 mm). When the wire moves from horizontal to vertical and vice versa, the distance from the beginning of the bend to the nearest nail or staple should be 10 ... 15 mm.
In the case of laying wires on concrete or other durable material, it is recommended to use special clips (brackets) that are attached to the surface by gluing. When attaching the wire with nails, holes are drilled along the wire laying route, wooden or plugs are driven into the holes, to which the wire is attached with steel nails or glue.
Wires and cables are fixed with nails or staples at the input to the devices and junction boxes at a distance of 50 ... 100 mm from them. For ease of maintenance in the device or junction box, a supply of wire 50 ... 100 mm should be provided.
Distance from cables and insulated wires laid openly, directly over the elements building structure the premises to the places of open placement (storage) of combustible materials must be at least 0.6 m.
Laying electrical wiring in pipes
Steel pipes may be used to protect electrical wiring only in cases specifically justified in the project and in the inspection report. Applicable for electrical wiring steel pipes must have an inner surface that prevents damage to the insulation of the wires when they are pulled into the pipe.
Steel pipes laid in rooms with a chemically active environment, inside and out, must have an anti-corrosion coating that is resistant to the conditions of this environment. Insulating sleeves should be installed at the points where the wires exit the steel pipes.

- 1.7 m for pipes with a diameter of 50 mm.
Polyethylene and polypropylene pipes should be connected by welding or in sockets by hot casing in sockets. To connect vinyl plastic pipes, it is necessary to use couplings and sockets, followed by gluing. To connect electrical wiring laid in polyethylene pipes, plastic junction and branch boxes should be used. The pipes must be connected to the boxes by a tight fit of the ends of the pipes on the branch pipes of the boxes, as well as using couplings. Vinyl plastic pipes must be connected to vinyl plastic boxes by gluing the end of the pipe to the box nozzles.
The direction of the protective pipes is changed by bending. When bending pipes, as a rule, normalized angles of rotation - 90, 120 and 135 ° - and normalized bending radii - 400, 800 and 1000 mm should be used. As flexible inserts in protective pipes in the presence of complex turns and angles of transition pipes from one plane to another and for the installation of temperature compensators, flexible metal hoses should be used.
Wires and cables in pipes should lie freely, without tension, the total cross section calculated from their outer diameters should not exceed 20 ... 30% of the pipe cross section. Combined laying of power cables and an alarm loop in one pipe is not allowed. When laying wires in one pipe, their number should not exceed 30.

Connection, branching and termination of conductors of wires and cables must be carried out by crimping, welding, soldering or using clamps (screw, bolt, etc.). In places of connection, branching and connection of cores of wires or cables, a reserve of wire (cable) must be provided, which ensures the possibility of reconnection, branching or connection.
The connection and branching of wires and cables, with the exception of wires laid on insulating supports, must be carried out in junction and branch boxes, inside the housings of technical equipment. Do not use screw connections in places with high vibration or humidity.
Fire-resistant seals (asbestos, slag wool, sand, etc.) must be provided in places where wires and cables for power supply of technical signaling equipment pass through walls or ceilings.
The laying of cables in underground sewerage structures must be carried out in accordance with the project and drawn up by an act.
Requirements for the installation of technical means of signaling in fire hazardous areas
Technical means of signaling, operating from the AC mains, as a rule, should be installed outside fire hazardous areas. When installing technical means of signaling openly on fireproof vertical building bases and in a closed fireproof cabinet, natural heat exchange must be ensured. Ventilation openings are made in the form of blinds.

The gaps between the wires or cables and the pipe at the passage point must be tightly sealed with an easily pierced composition of non-combustible materials.
Special requirements for the installation of technical means of signaling in hazardous areas
Installation of technical means of signaling in hazardous areas should be carried out in strict accordance with the project of a specialized design organization and the requirements of the PUE.
Technical means of signaling (with the exception of detectors included in intrinsically safe circuits) intended for installation in hazardous areas must (depending on the classes of hazardous areas) be designed to meet the requirements of Ch. 7.3. PUE. At the same time, explosion-proof technical means of signaling must correspond to the explosion protection category and group of explosive mixtures that can form in the zone, and have the appropriate explosion protection marking.

Start-up and adjustment works during installation of OPS installations
To carry out commissioning works, the customer must: agree with the installation and commissioning organization on the deadlines for performing the work provided for in the general schedule; ensure the availability of sources of electricity; ensure general terms and Conditions labor safety.
Prior to commissioning, individual tests (adjustment, adjustment, adjustment) of control panels, signaling and starting devices, detectors, etc. must be carried out during the installation process. in accordance with technical descriptions, instructions, PUE.
Commissioning works are carried out in three stages:
- - preparatory work;
- adjustment work;
— complex adjustment of technical means.
At the stage of preparatory work, the operational documents for the technical means of signaling should be studied, the workplaces of the adjusters should be equipped with the necessary inventory and auxiliary equipment.
At the stages of commissioning and complex commissioning, adjustments to the previously carried out adjustment of technical means should be made, including:
- - bringing the settings to the values at which the technical means can be used in operation;
- bringing the equipment to the operating mode;
- checking the interaction of all its elements in the "Alarm", "Fire", "Fault", etc. modes.
Commissioning works are considered completed after receiving the parameters and modes provided for by the project and technical documentation that ensure stable and stable operation of technical means (without false alarms).
Labor safety requirements
Installation and adjustment work should be started only after the implementation of safety measures. Work with technical means of signaling must be carried out in compliance with the EMP, current regulatory requirements and instructions for labor safety.
When working at height, use only ladders or ladders. The use of improvised means is strictly prohibited. When using ladders, the presence of a second person is mandatory. The lower ends of the ladder should have stops in the form of metal spikes or rubber tips.
When installing, adjusting and maintaining technical means of signaling, it is also necessary to be guided by the safety sections of the technical documentation of manufacturers, departmental safety instructions for installing and adjusting control devices and automation equipment.
More detailed information for safety regulations for installation and commissioning of security systems, see.
A complete list of instructional materials is provided as part of the information base for installers and designers of security systems.
RD 78.36.003-2002 provides for requirements for security alarm systems.
Protection of the perimeter of the territory and open areas.
The technical means of perimeter security alarms should be selected depending on the type of perceived threat to the object, interference situation, terrain, the length and technical strength of the perimeter, the type of fence, the presence of roads along the perimeter, the exclusion zone, its width.
The security alarm of the perimeter of the object is designed, as a rule, as a one-line one.
To strengthen security, determine the direction of movement of the intruder, block vulnerabilities, multi-line security should be used.
Perimeter security alarm technical means can be placed on the fence, buildings, structures, structures or in the exclusion zone. Security detectors should be installed on walls, special poles or racks, ensuring the absence of oscillations, vibrations.
Medium and large-capacity control panels (hubs), SPI, automated notification transmission systems (ASPI) and radio notification transmission systems (RSPI) can be used as internal security consoles. Internal security consoles can operate both with direct round-the-clock duty of personnel on them, and autonomously in the "Self-protection" mode.
Installation of security detectors on the top of the fence should be carried out only if the fence has a height of at least 2 m.
At the checkpoint, in the security room, technical devices for graphic display of the protected perimeter (computer, light panel with a mnemonic diagram of the protected perimeter and other devices) should be installed.
All equipment included in the perimeter alarm system must be tamper-proof.
Open areas with material assets on the territory of the facility must have a warning fence and be equipped with volumetric, surface or linear detectors of various operating principles.
Protection of the building, premises, individual items. All premises with permanent or temporary storage of material assets, as well as all vulnerabilities of the building (windows, doors, hatches, ventilation shafts, ducts, etc.), through which unauthorized entry into the premises of the object is possible, should be equipped with technical means of security alarms.
Objects of subgroups AI, AII and BII are equipped with a multi-line alarm system, objects of subgroup BI - single-line.
The first line of the security alarm, depending on the type of alleged threats to the object, is blocked by:
wooden entrance doors, loading and unloading hatches, gates - for "opening" and "destruction" ("break");
glazed structures - for "opening" and "destruction" ("breaking") of glass;
metal doors, gates - for "opening" and "destruction",
walls, ceilings and partitions that do not meet the requirements of this Guiding Document or behind which the premises of other owners are located, allowing for hidden work to destroy the wall - for "destruction" ("break"),
shells of storages of values - for "destruction" ("break") and "impact";
grilles, blinds and other protective structures installed on the outside of the window opening - for "opening" and "destruction";
ventilation ducts, chimneys, input / output of communications with a cross section of more than 200x200 mm - for "destruction" ("break");
Protection of staff and site visitors.
For the prompt transmission of messages to the central security console (CSC) and / or to the duty department of the internal affairs bodies about illegal actions against personnel or visitors (for example, robbery attacks, hooligan actions, threats), the object must be equipped with alarm devices (TS): mechanical buttons, radio buttons, remote controls, pedals, optical-electronic detectors and other devices.
The alarm system is organized "without the right to turn off".
TS devices at the facility should be installed:
in vaults, pantries, safe rooms;
in the premises for the storage of weapons and ammunition;
at the workplaces of cashiers;
at the workplaces of personnel carrying out operations with narcotic drugs and psychotropic substances;
in the offices of the management of the organization and the chief accountant;
at the main entrance and emergency exits to the building;
at guard posts and premises located in a building, structure, structure and in a protected area;
in corridors, at doors and openings through which valuables are moved;
in a protected area at the main entrance (entrance) and emergency exits (exits);
in other places at the request of the head (owner) of the facility or on the recommendation of a private security officer.
The hand and foot devices of the vehicle must be placed in places as inconspicuous as possible for visitors. Managers, responsible persons, owners of the facility, together with a representative of the private security unit, determine the places for the hidden installation of buttons or alarm pedals at the workplaces of employees.
The management of the facility, employees of the security and guard services should be equipped with mobile devices of the vehicle operating over a radio channel (radio buttons or remote key fobs).
Places for storing money, precious metals, stones and products made from them (tables of cashiers, metal cabinets or safes, cash registers, shop windows, trays, sales counters), in addition, must be equipped with special technical means (traps) that form alarms without the participation of personnel when an intruder tries to take possession of valuables. These technical means should be included in the alarm loops of the facility.
Organization of the transmission of information about the alarm. The transfer of notifications about the operation of the security alarm from the object to the ARC can be carried out from the small-capacity control panel, the internal security console or the devices of the terminal notification transmission system (SPI).
The number of security alarm lines displayed on the ARC by separate numbers is determined by a joint decision of the management of the facility and the private security unit based on the category of the facility, risk analysis and potential threats to the facility, the possibilities of integrating and documenting the control panel (internal security console or terminal device) of incoming information, as well as the procedure for organizing the duty of security personnel at the facility.
The minimum required number of security alarm lines displayed on the ARC from the entire protected facility should be for a subgroup.
BI - one united frontier (the first is the perimeter);
AI, BII - two united borders (the first is the perimeter and the second is the volume).
In addition, if there are special premises at the facility (subgroup AII, safes, weapons rooms and other premises requiring increased security measures), the boundaries of the security alarm of these premises are also subject to the ARC.
If there is an internal security console at the facility with round-the-clock duty of its own security service or a private security institution, the ARC displays:
one common signal that unites all the boundaries of the security alarm of the object, with the exception of the boundaries of the special premises of the object;
security alarm boundaries (perimeter and volume) of special premises.
At the same time, registration of all incoming information from each security line of premises on the internal security console should be ensured.
From protected objects, "auto redial" should be carried out by two or more telephone numbers.
In order to exclude access of unauthorized persons to detectors, control panels, splitting boxes, and other security equipment installed at the facility, measures must be taken to mask and covertly install them. The covers of the terminal blocks of these devices must be sealed (sealed) by an electrician of the security guard or an engineering and technical worker of the private security unit indicating the name and date in the technical documentation of the facility.
Distribution cabinets intended for crossing alarm loops must be locked, sealed and have blocking (anti-tamper) buttons connected to individual numbers of the internal security console "without the right to turn off", and in the absence of an internal security console - to the ARC as part of the alarm system .
When developing a fire alarm project, it is necessary to take into account the requirements of NPB 88-2001 - “Norms and rules for the design of fire extinguishing and alarm installations”.
The building of a medical institution belongs to administrative buildings, therefore, when using automatic fire alarms, its premises should be equipped with smoke fire detectors.
Smoke fire detector - a fire detector that reacts to particles of solid or liquid products of combustion and (or) pyrolysis in the atmosphere.
At least two fire detectors should be installed in each protected room, since the height of the premises of the object does not exceed 3.5 m, the maximum distance between the detectors is not more than 9 m, the distance from the detector to the wall is not more than 4.5 m.
the main factor in the occurrence of a fire in the initial stage is the appearance of smoke;
the presence of people is possible in the protected premises.
Such detectors should be included in a unified fire alarm system with the output of alarm notices to a fire alarm control device located in the room on duty. A fire alarm control device is a device designed to receive signals from fire detectors, provide power to active fire detectors, issue information to light, sound annunciators and centralized monitoring panels, as well as the formation of a starting impulse for launching a fire control device.
Manual fire detector - a device designed to manually turn on the fire alarm signal in fire alarm and fire extinguishing systems.
Manual fire detectors should be installed on walls and structures at a height of 1.5 m from the ground or floor level in corridors, halls, lobbies, on landings, at exits from the building.
But an effective fire alarm system must necessarily include a fire warning system for people.
Warning and evacuation management system (SOUE) is a set of organizational measures and technical means designed to timely inform people about the occurrence of a fire and (or) the need and ways of evacuation. The SOUE must function for the time necessary to complete the evacuation of people from the building.
The building of the object in question belongs to the second type of SOUE, therefore, it must be equipped with light annunciators "Exit" and sound annunciators (siren or tinted signal).
To ensure clear audibility, the audio signals of the SOUE should provide a sound level of at least 15 dB above the permissible sound level of constant noise in the protected room.
A combined sound and light annunciator should be placed on the outer wall of the building in front of the entrance.

The detector should issue an intrusion alert when the standard target moves within 3 m of the start of movement. Moving a target to the detector at a distance of up to 0.2 m should not cause an intrusion notification to be issued.
The tests should be carried out at target speeds of approximately 0.3; 1 and 3 m/s or the highest and lowest speeds of movement, if the technical specifications for detectors of specific types set a wider range of detected speeds.
6.2.3 Recovery time of the detector to standby mode
The standard target should be located in front of the detector at the edge of the detection zone and move towards it at a speed of approximately 1 m/s. When the detector issues an alarm notification, the distance from the detector to the target is recorded. After that, the standard target returns to the border of the detection zone.
The target is then replaced by an object or person other than the standard target, which moves towards the detector before it issues an alarm notification. After that, the movement stops. Not earlier than 10 s from the boundary of the detection zone, the standard target begins to move at a speed of approximately 1 m/s. The distance from the detector to the target at which the alert is issued must not differ from that measured in the first part of the test by more than 10%.

The standard target should be located in front of the detector, beyond the mark corresponding to the selected range, and move towards it at a speed of approximately 1 m/s. The distance from the detector to the target is fixed when it issues an alarm notification.
After at least seven days of operation of the detector in standby mode, the tests are repeated under the initial conditions. The distance again fixed during the second test should not differ from the distance measured in the first case by more than 10%.
6.2.6 Tamper evident
If there are means to protect the detector from opening, its housing must be opened using the tools commonly used for these purposes in such a way as to gain access to the controls and adjustments of the detector.
Before such access is obtained, the tamper-evident means must sound an alarm.
The test should be repeated using a knife or screwdriver in an attempt to bypass the tamper-evident devices without damaging the detector.
6.2.7 Trunk security
6.2.8 Range of detected speeds
The standard target is placed in front of the detector at the boundary of the detection zone on its center line and moves towards the detector. The detector must issue an intrusion alert when the standard target moves within 3 m of the start of movement.
Tests are carried out when moving a standard target at speeds of 0.3; 1 and 3 m/s.
