Equipment for installation of security fire alarms. DIY fire alarm installation

At the moment, security and fire alarms have become quite common, which increase the level of protection of various objects. Thanks to its "many-sided" functionality and component composition, not only a fire is detected in a timely manner, but also a thorough control over the protected area is carried out. Such a device is quite complicated and expensive to install and maintain, but you will not find electronic device which is so reliable.

How does a fire alarm system work?

The fire protection system is a whole "set" of different technical devices that provide fire safety various kinds buildings, equipment, people, as well as material values. It includes two systems: notification of people in the building and fire alarm.

Due to the fact that the software and hardware dispatcher was installed, you will always see the source of ignition on the site plan. If semi-automatic mode was set on the alarm, then after an alarm signal is received from it, the security service must turn on the fire warning system for personnel and at the same time activate visual, voice, and voice messages.

When the fire alarm in the building is confirmed, the main signal will be transmitted to the ACS - the "message" system and thereby bring all the alarm elements into the emergency evacuation mode. Also, the signal will go to the control system of various engineering networks buildings, after which they will go into fire danger mode.

The automatic fire device performs the following functions:

• Identification of the fire zone;
• Detection of the focus after 2-time confirmation from the moment of registration;
• Network troubleshooting on short circuit, as well as a cliff with reference to the building plan;
• Detection of the focus at the initial stage;
• Management of different blocks with displaying the results obtained on the dispatcher workstation;
• Viewing the fire-prevention state of the areas of the building on the detailed, as well as general plan, which are displayed on the dispatcher console in text and graphic format.

Features of design and calculation

The design of the fire alarm system is the main stage on which the effective operation of the entire system depends. Such work should be done by professionals, since this is a complex scheme with a number of calculations, a significant number of devices and their location. However, since they are all interconnected by a loop, it is therefore necessary to design the trajectory of further laying. In addition, one must take into account possible nuances, which are being developed in the project to eliminate emerging threats.

However, the development of an FEA project is a subjective process, since each object must be carefully studied taking into account the characteristics of use, as well as plans. And you need to evaluate:

• The complexity of the design;
• The size of the rooms;
• Planning specifics.

Attention should also be paid to places with the most likely outbreak. The design of the fire protection system is carried out taking into account the PUE, as well as DSTU. The project includes a huge number of different works:

• Terms of reference, which takes into account all the wishes of the client;
• Study of premises;
• Creation of a standard project with all estimated estimates for the work performed;
• After agreeing on all the nuances with the client, all documents and estimates are signed;
• Installing and testing the operation of the OPS.

In the process of preparing for the installation of the alarm, it is necessary to carry out many calculations, thanks to which you can choose the most perfect look devices and at the same time avoid additional expenses, for example, with the maintenance of detectors or the installation of the system itself.

Most milestone calculations is to determine the ideal capacity for the energy source itself. In other words, it is necessary to decide which type of power supply is most suitable for connecting the detectors. Not only batteries, but also ordinary batteries can act as a source.

The required source capacity is usually indicated in the fire alarm operating instructions themselves. Therefore, it is necessary to check the value on the battery case with the available information in the instructions. If the power capacity is not enough, then buy a more powerful device. If you are connecting several batteries, then you need to make sure that they have the same voltage.

Also, specify the required wire cross-section for the OPS and pay attention to the characteristics of the battery capacity for different operating modes (alarms, standby). Next, you need to summarize these values, after which you will get the total battery capacity of your particular OPS.

Types of systems

To date, there are a huge number of different fire alarms of various levels of complexity. However, they all perform the same function - they control the protected object with the help of detectors. Most modern fire systems can transmit a signal to the main security console at a distance and even perform many other service functions. But their main task is the timely detection of fire on the territory of the facility or illegal entry. Depending on the method of determining the fire threat, systems can be divided into the following types:

• Non-address. Conventional sensors (manual, thermal, as well as smoke) are connected to the receiving and control devices, which display only the number of their loop. At the same time, they do not transmit the address of the room, as well as the number, to the main panel.
• The address system works according to the following principle - the control panel receives data from the detectors, due to which the exact area of ​​the fire is determined.
• Addressable analog signaling is a very efficient and reliable device, since the received information is sent to the main panel, and then it is analyzed by the main processor. To give an alarm or not, the software package decides, and not a specific detector.
• threshold system with radial plumes the most budgetary, however, its installation will be expensive. Wherein this species alarms can often give false alarms, so it will be necessary to duplicate the detectors, which will lead to an increase in costs.
• The modular threshold system is more advanced, since you can track any malfunction on the PC, which means that you can immediately take the necessary measures and troubleshoot. The disadvantage is the high price.

The main types of sensors

Fire detectors or sensors are special devices that allow you to record certain properties of fire ignition with its initial detection and further prevention. Also, sensors are the main element of the entire alarm system, providing fire safety. The reliability of the detector determines, in general, the effective operation of the system, and they are divided into such types as:

Heat detectors

They react to changes in air temperature and can be divided into:

Use a heat detector only if heat is the main symptom of a fire.

Smoke detectors

They help detect the presence of smoke in the air, and they work on the principle of dispersion infrared radiation on smoke particles. The disadvantage of smoke sensors is that they are able to operate even with a significant amount of dust and steam in the room. But meanwhile they are very popular, although smoke detectors are not used in smoking rooms or heavily dusty rooms.

Flame detectors

They work only from an open flame or a smoldering hearth. They are installed mainly in rooms where fire is possible without the initial release of smoke. They can also detect fire initial stages, that is, in the absence of most factors, such as temperature changes and smoke. Flame detectors are used in industrial premises, characterized by significant heat transfer and dust content.

Gas leak detector

These sensors are suitable for different applications because they react to smoke, heat and even gas in the air. They operate on the principle of identifying a series of chemical reactions. These detectors contain particles of carbon monoxide, and the settings, working in automatic mode, can determine the ideal temperature of the monoxide, when the temperature changes, this is signaled.

Combined sensors

Able to detect signs of fire immediately in several ways. Basically, these are devices that have the functions of not only a smoke, but also a heat sensor, thanks to which it is possible to specifically identify signs of fire, and then notify people.

Installation and connection of fire and security alarms

1. You must define required amount detectors. And for this you need to know the height of the ceiling of the room, as well as its area. According to the documentation, with a ceiling height of more than 3.5 meters and 80 sq. m. area, you will need one detector, but safety regulations state that even in small room at least 2 sensors must be installed. Therefore, it is best to follow these rules.
2. Where the sensors will be installed, it is necessary to designate the place. The distance from the detector to the wall should be about 450 cm, while the distance between the sensors should be about 900 cm. This rule relevant for single-level ceilings With maximum height 350 cm. Wall detectors are installed at a distance of 200 mm from the ceiling.
3. At the initially marked places, it is necessary to fix the detectors, after which they are connected to a power source with 2-wire wires. Devices must be connected in series with each other. The resistor is installed in the block of the latest sensor.
4. After you connect the last detector, they must be checked for operability. To do this, it is necessary to hold a flame from a lit match or candle near the detector.

Where and how to install fire detectors

The standards for the installation of OPS detectors are quite liberal: between the sensors it is 9 meters, from the wall - 4.5 meters. However, this placement is done solely for the sake of comfortable configuration of a certain fire system. In this regard, we can conclude that the installation and location of the detectors is a more complicated matter.

When installing sensors on walls, the distance must be at least 200 cm, otherwise they will give a false alarm, as they will be in the “smoke pocket”.

The sensitivity of the detector depends directly on the distance of the source of danger and it does not survey the entire hemisphere. In an empty room, the area monitored by the sensor depends only on the ceiling height.

By flame:

• Up to 15 sq.m. - from 6 to 9 meters;
• Up to 20 sq.m. - from 3.5 to 6 meters;
• Up to 25 sq.m. - 3.5 meters;
• More than 9 meters - it will be impossible to control, because the ignition will become a fire, and the sensor itself will not work.

• Up to 85 sq.m. - it is up to 3.5 meters;
• Up to 70 sq.m. - this is from 3.5 to 6 meters;
• Up to 65 sq.m. - it is from 6 to 10 meters;
• Up to 55 sq.m. - from 10 meters.

However exact calculation The location of the detectors needs to be simulated on a PC or by a professional.

How the notification system works

When the detectors detect a fire, the fire warning system automatically turns on. Warning systems according to their principle of operation, as well as composition are divided into:

The notification function is realized thanks to the output as well as the input interfaces. In order for the information to be displayed, alphanumeric and light indicators, as well as sound signaling devices, are used.

Possible malfunctions after installation

Improper prevention is the main cause of fire alarm failures. In other words, it is necessary to constantly carry out all preventive work. Smoke detectors often fail, as various particles and other debris enter their chamber. However, there are loop breaks or system errors that also cause malfunctions.

Considering the fire alarm system, the main problems are highlighted:

Often significant damage to fire alarms is caused by polluted and heavily dusty work areas, high humidity or high temperature. Also, banal reasons, for example, cable breakage, due to which the alarm can even squeak, flash, and so on, even without fire, become the cause of failure of the OPS. But the most serious cause of malfunctions is still the intervention of unskilled specialists, amateur performance, or the term of operation approaching completion.

How to remove the fire alarm yourself

If the alarm went off for no reason, then it can be completely turned off. The most elementary option is to remove power (battery) from the sensor or disconnect the control panel from the network.

Attention! AT this case the fire alarm will become useless and will not be able to warn you of a real fire.

In addition, many fire alarms are equipped with auxiliary power sources and a button located on the sensor on the front side, which will also need to be turned off. When you press the button, the device goes into alarm mode, and the sound signal is reset automatically.

Also, the fire alarm is turned off using a centralized control panel, but for this you need to know the password. If you cannot find out the cause of the device failure, then solve the issue radically - bite the wires that go to the sensor, but in this case the device will stop working altogether and will simply resemble a decorative element.

Video: how to connect an OPS with your own hands

Human safety is a top priority, regardless of whether it is at the workplace or at home. This can be ensured by installing the OPS in combination with other devices. But in order for the alarm to work as efficiently as possible, it is necessary to adhere to certain rules design, installation and operation.

In this article, we will talk about how correct installation and installation of fire alarms. We want to note right away that such an installation requires the mandatory presence of certain knowledge!

For convenience, we have divided the article into the following parts:

Proper fire alarm installation

First you need to develop a project that describes the main nuances during the installation of a fire alarm. First, the place where the control point is located is determined, and then the methods of conducting communications. You also need to familiarize yourself with the presence of fire extinguishing modules, types of sensors and other information. But be sure to take into account that the signal wires should in no case be located near a heat source. Control equipment and sensors should only be installed in positions where there is less chance of hitting them and causing damage.

Then you need to carry out the installation of equipment, so you need to decide in advance what the complexity of the fire alarm is. It depends on the level of fire risk in the room, which can be completely different. If the room has a small area, then you need to install non-address alarm systems, but if the object has a large area, then you need to install an address system. The fact is that the address system quickly determines the place where the fire occurred, so it is preferable. You do not have to spend a lot of time searching for the room in which the fire occurred.

The address-analogue system is the most popular in recent times. All this is due to the fact that special sensors make it possible to know the change in temperature and even the level of smoke in the room. In principle, each fire alarm system provides detailed information about the state of the room, because there are many sensors in the room that have a common connection using loops, which makes it possible to connect to a computer and configure. If the sensor finds a signal, then the light or sound alarm is activated. If the fire alarm has special modules that start fire extinguishing, then the control system will definitely activate it.

Features of installing fire alarm sensors

A smoke detector is a fire alarm sensor, it is an extremely simple device. It has a small size and is attached to the ceiling or wall in the apartment. There are two main types: photovoltaic and ionization. The photovoltaic is triggered if smoke passes between the photo and the LEDs. And the ionization is started due to the ingress of smoke into the current that passes between the wires. It is impossible to say for sure which of the options is preferable, since the ionization turns on due to a strong fire, and the photovoltaic due to huge amount smoke. Therefore, our online magazine site believes that the best option will use two sensors at once.

It is recommended to install sensors between places where a fire can start without any problems. For example, in the kitchen while cooking. It is also recommended to install in the living room, bedroom, corridor and other places. Keep in mind that extra protection never hurts. True, installation in the kitchen requires special installation, because the humidity there is steadily increased, so the sensor may work erroneously. Be sure to install the unit as far as possible from batteries and heaters, fluorescent lights, air vents, and so on.

Almost all fire detectors use batteries to last, so it's a good idea to play it safe and check them as often as possible. You can check the sensor itself, it's easy to do - hold a lit candle directly near the sensor, and the fire will provoke its activation. Remember that dust on the sensor can dampen its performance, so wipe it down as often as possible.

Almost always, the fire safety sensor is mounted in the ceiling at a distance of 300 mm from lighting fixtures and walls. The wall model is installed at a distance of 200 mm from the ceiling so that there are no empty air spaces where the smoke stops circulating and the sensor can be activated. If the ceiling cross beams with a thickness of about 10 centimeters, then the sensor must be fixed to the base, and not between the beams. With a large thickness of the beams, if it exceeds 10 centimeters, contact a specialist.

Absolutely all floors should have sensors. The first is installed above the base of the stairs, the second in the middle of the hallway, the third on the ceiling in the bedroom, and so on. Then installation is carried out additional sensors in the hallway, living room, kitchen and other places where there are electric heaters.

What wires to use when installing a fire alarm?

Before choosing cables and wires, you need to study the requirements that apply to them in Russia. During the installation of a fire alarm, it is necessary to lay the loops in such a way as to automatically monitor their condition along the entire length. As a rule, loops have wires in which the cores are made of copper. If during installation you do not think about the fact that you will control fire extinguishing installations automatically or a smoke removal system with voice notification, then you can not allocate an additional communication channel. If such control is planned, then you must conduct a communication channel and connecting lines made in the form of telephone cables.

Connecting lines with telephone or control wires should have an additional margin of approximately 10% loops. It is also possible to connect radial loops directly to the fire appliance, but only if the information capacity does not exceed 20 loops. But if the alarm is of the ring type, then the end and the beginning are connected directly to the terminals that are in the control panel. It is impossible to allow laying in the corrugation box and hose if the wires are extremely high voltage. If the parallel strip has a voltage of about 60 volts, then there should be a distance of about 0.5 m to lighting and power devices. Do not forget that it is advisable to divide the cables into segments and use junction boxes. The installation is best carried out in an accessible place at a suitable height, especially for a device installed at the end of a loop, because it allows visual control during operation.

Fire alarm installation rules

Control devices, together with receiving and control devices, must be installed in the territory where duty personnel are located daily. Of course, unmanned on-site installation is sometimes quite affordable if there is a reason for it. For example, if there are no employees who are on duty every day for 24 hours, but there is another point that receives information about what is happening at your facility. That is why in the room where you install the sensors, you need to make sure that the fire department and security alarm worked correctly, and unauthorized access was denied.

The number of capacitance in the control panels and the number of loops that are needed to work with fire notices should be about 10 pieces and 10 percent. Control and reception devices must be mounted on walls, structures and partitions that do not contain combustible materials. The installation of such equipment is quite realistic on structures that are made of combustible materials, but only if they are covered with steel sheet with a thickness of about 1 mm or other non-combustible sheet material with a thickness of about 10 mm. It is very important that the material protrudes beyond the contour of the mounted equipment by about 10 centimeters.

Do not forget that the distance from the upper edge of the control panel used to the ceiling of the room, which is made of non-combustible materials, should be about 1 meter. With the adjacent position of control panels in the amount of several pieces, as well as control devices, it is necessary that there is a distance of about 50 millimeters between them. You also need to take care of sufficient height, since control panels set in such a way that the distance to the operating controls is about one meter.

A room with personnel or a fire station should be located on the basement or first floor of the building. You can arrange a room above the first floor, but on condition that the exit is in the corridor or lobby. Also, the exit should be adjacent to the landing, so that there is a quick exit to the outside of the building. The distance from the premises of the fire post to the room with personnel who work daily for 24 hours must be at least 25 meters. It is very important that the room meets the necessary characteristics:

1. Minimum area 15 square meters, preferably more.


2. The air humidity is 80% and the temperature is about 18-25 degrees Celsius.


3. artificial and daylight should be comfortable. Make sure you have emergency lighting.


4. Illumination should be as follows: natural - 100 lux, artificial (fluorescent lamps) - 150 lux.

How can I get a fire alarm license?

To obtain a license for the maintenance, installation and repair of automatic fire alarm devices, as well as automatic fire extinguishing systems, you need to fill out Required documents and spend a lot of time. For example, if you are registering your company or want to keep staff in an office where there is an increased risk of fire, then you first need to decide on the system itself. Perhaps a certain automatic fire extinguishing system will suit you better than another. Next, issue a certificate in which you indicate the material and technical base and write down all the mechanisms and machines with the nomenclature and the full volume that will be needed to carry out the work. Highly important nuance is that it is necessary to evaluate and check the material and technical base during the preparation of the act, which demonstrates the assessment of compliance with the conditions, requirements and license as a whole.

Next, think over a system that controls the work and determines its quality. Here you will need to provide a copy of the manual for the use of devices, a certificate from production, where control forms will be demonstrated, and so on. Forms of control can be output, input and operational. After that, you need to write an application and submit it to the authority that issues the license. When filling out the application, it is very important to take into account the legislation of Russia in relation to the activities of your organization.

An important role is played by the operating personnel and their qualifications, so you must provide data on the qualifications of all employees who will provide services on this equipment. To check the qualifications of your staff who will service and install new equipment that guarantees safety from fire in the room - check their education, for example, check their skills on tests or just look at the very presence of secondary, higher or special education. Experience and work experience are also very important, since, according to the law, only people who have worked in the Russian Emergencies Ministry for at least five years can be engaged in the maintenance of such equipment. Obtaining a license depends on how conscientiously the employees got a job, and if experience and education are faked, new staff will have to be recruited.

Any organization needs a fire alarm and additional equipment that can fix the location of a fire. You should not save on equipment and maintenance, because in the event of an unfortunate set of circumstances, you can lose absolutely everything.

Before you install a fire alarm, you need to understand the types of such systems and choose exactly the type that suits your specific requirements. You can install the system yourself, but it's better to call a special team. If desired, the owner of the system can register it with the State Fire Supervision Authority.

Types of systems

All types of fire alarm systems can be divided into several types.

1. Threshold systems with radial plumes.
2. Threshold systems having a modular structure.
3. Combined system.

Threshold systems with radial plumes

Threshold systems equipped with radial loops are popular for one reason only - they are very cheap. At the same time, the installation of such equipment will be quite expensive. Such a system has a lot of shortcomings that are difficult to notice immediately after installation.

In particular, the control panel may give false signals. The number of such false notifications here is an order of magnitude higher than in any other devices. At least about two detectors should be installed in one room, and this leads to an increase in costs. While the equipment is very economical, installing it and spending extra on detectors will add up to a very significant overall cost.

With an abundance of sensors, it will be impossible to track them from one computer.

Also, a certain threshold is set in the gearbox, at which a signal is given. The serviceability of the alarm is almost impossible to check; if it breaks down, the sound may not be heard. PKP is highly dependent on the human factor.

In a word, such a system has much more disadvantages than advantages. When installing an alarm for serious purposes, it is better to choose something else.

Threshold systems having a modular structure

Such systems are inexpensive, like the previous type of alarms. They have almost the same drawbacks: expensive installation, a certain threshold for signaling, and dependence on the human factor.

However, this type of alarm can be freely controlled from one remote control or computer. In addition, two units can be mounted simultaneously here.

Such a system has a fundamentally different structure than the previous two. She works differently. All sensors in it are combined into a common unit, while they are regularly checked from the control panel. Signals from sensors can have four responses: "normal", "fire", "malfunction", "absence".

The disadvantage of this type of alarm is that they detect and report a fire too late. Other than that, it's a very good system.

This system has an optimal ratio of price and quality, with the help of a polling panel you can always detect a malfunction in the sensors in time, as well as get a lot of useful information.

Up to two hundred sensors can be included in one loop of such an alarm. To appreciate all the advantages of this system, you need to understand how this type of fire alarm works. It assumes the presence of twisted pairs, this is its main advantage and at the same time a disadvantage. When leaving any sensor standing, the system itself remains fully operational.

Sensors do not have any specific signal threshold. They simply register the atmosphere at their assigned point and send the data to the control panel. This allows you to quickly identify the source of ignition. In addition, such a device of the system allows you to find out in time about all the malfunctions in the network.

The cost of installing an analog addressable system itself will be inexpensive, but the equipment will cost decently. Probably the only drawback of this signaling is that the protocol requires the presence of a twisted pair cable.

Combined systems

Combined fire alarms are the most powerful. They allow the installation of several thousand sensors and devices. They have a very wide range of accessories.

Fire alarm systems and devices of this type are controlled from a single control point, which greatly facilitates security monitoring. There are practically no disadvantages to a combined fire alarm, except that it can cost a decent amount.

Installation and dismantling

Installation of an alarm system requires compliance with special rules that are prescribed in normative documentation. It is advisable to install such systems with the help of professionals if the owner of the premises does not have the skills to work with such systems.

Some owners ask if it is possible to create a fire alarm with their own hands, that is, to assemble the device itself at home. Yes, this is quite possible, but within certain limits. Complex systems cannot be created independently. The master can only make the simplest devices, and no one can guarantee that they will function properly.

Sometimes the fire system works without any ignition. Frightened owners do not know how to turn off the fire alarm. The sound of this system is very specific and hardly anyone will like it. To restore silence and order, you must do the following.

1. First you need to find out the reason why the alarm went off. There may have been smoke or a small fire. You need to ventilate the room immediately.
2. If, nevertheless, the system worked for no reason, then you need to decide on its type. The simplest alarm with sensors is simply turned off. To do this, just remove the power source from the sensors themselves. With a more complex alarm device, you need to go to the control panel. The system is often disabled only after the appropriate code has been entered.
3. A radical way to eliminate noise is to bite the alarm wires. In case you need to restore it, you will have to carry out a number of works.

A fire alarm system is a complex system in which different types of devices interact in an orderly manner: control panels, sensors, warning elements, communication lines, autonomous power supplies, peripheral equipment. Installing equipment is not easy - you need to know the features of installing a fire alarm.

According to the current legislation, industrial enterprises are required to have on their territory fire protection. Many owners of private houses and apartments also prefer to use precautionary measures. Experts recommend: before installing fire alarm systems, it is necessary to determine their type.

Simple and complex equipment

Fire alarm systems differ from each other in their configuration and functionality.

They are different:

1. Threshold equipment equipped with radial loops has become widespread due to the low cost of its components. The name is based on the principle of operation of the device. The main control device serves sensors with an individual sensitivity threshold. Fire alarm installation involves the use of several units of detectors per room. The main disadvantage installed equipment is elevated level false signals.
2. Threshold signaling with a modular structure is similar to the previous scheme. The difference is that one control panel simultaneously controls the operation of communication lines, and installation and operation are designed for the use of two units.
3. Address-interrogating devices have a different structure compared to the previous versions. The operation of the sensors is monitored by a module with an annular loop, which allows you to filter out unnecessary information. The alarm circuit is reliable and easy to design.
4. The address-analogue line is a modern device. Each detector has an individual address where it sends a signal about its operating status. The sensors are twisted pairs. If any element fails, the system will continue to function.
5. The combined system is installed indoors and outdoors. It is powerful, has a ring circuit using threshold and analog devices.

Regulations governing the installation of fire alarms

Fire alarm installation is carried out in accordance with GOST. Regulatory papers regulate the drafting of a fire system, the parameters of its elements and installation, including construction aspects. The basic rules are specified in the document on the means of fire and security alarm systems.

According to the regulation, design and installation should be focused on ease of maintenance, repair and protection from damage. Installation of alarm systems is carried out in each room using at least two sensors, except for stairwells, bathrooms. A number of documents contain special rules for different types devices.

Substation installation/assembly rules

The installation of a fire alarm system depends on the area of ​​the room and the height of the ceiling structures. For each device there is an individual instruction for installation and operation.

However, there are general rules mounting:

• The selection and configuration of the central control unit is carried out in accordance with the instructions. In simple models, there are several input connectors for connecting sensors. Output lines allow you to turn on devices that signal danger. Complex circuits additionally have a security function. For simplified installation, you can purchase a wireless fire alarm system kit. It has everything necessary components including fasteners.
• The laying of communication lines must be carried out in accordance with the requirements of SNiP. Only wires with copper conductors and heat-resistant winding are used. For internal installation corrugated pipe must be used. Each loop has a specific marking. Wires are subject to control along the entire length. For sensors, it is better to use two-wire and four-wire options. Installation of the fire alarm system assumes a 10% supply of loops. According to the rules, the laying of connecting wires with power cables is not allowed. The distance between the signal wires must be at least half a meter.
• Fire detectors control a certain sector, therefore they are mounted in places where open fire. According to the norms, they should be at a distance of 9 m from each other, not more than 4.5 m from the corners of the walls, not less than 0.2 m from the ceiling. Thermal sensors are located where the temperature rises sharply, with the exception of places where heating devices are used. Linear type sensors must be installed on opposite sides of the room.

After measurements and selection of locations for sensors with a central control unit, a fire and security alarm is installed.

How to install - do it yourself or through a contractor?

Proper installation of security and fire systems ensures the safety and security of property. According to the law, the design and commissioning works in the complex are carried out by specialized organizations that have permits from the Ministry of Emergency Situations. They conclude a contract with the customer for the maintenance of fire and security alarms.

Installation of systems is carried out on the basis of approved documentation. Specialists in a short time are able to install a fire alarm system with an extensive network of devices and logic circuits. People who are versed in electrical engineering can do a simple installation of fire systems with their own hands. A well-designed scheme is easy to legitimize.

Before you install fire and security systems with your own hands, you need to select and buy a certain type of alarm. If financial possibilities do not allow this, then the device can be made independently.

In this case, the alarm signal will be sent to the owner's phone, and not to the central control panel of the Ministry of Emergency Situations. You will have to call the fire department separately. Fire alarms in the home require consideration of some of the nuances:

1. the use of a multi-core cable in the winding to connect the sensors;
2. the use of sealed or chip sensors that are installed on door or window openings;
3. placement of sensors in accordance with the design of the ceiling according to established standards.
4. connect the system according to the instructions.

Recommendations for choosing a contractor - what to look for?

Installing and maintaining a fire alarm requires a serious approach. Such work should be carried out by highly qualified and experienced specialists. When choosing an executing company, you need to consider:

• having a license;
• stages of the organization's activities: study of the features of the premises, determination of the type of alarm system in relation to the object, design, cost calculation, installation;
• whether the company is a member of the National Association of Self-Regulatory Organizations of SROs or not.

How much will the installation cost?

Fire alarm calculations depend on its configuration and effective work constituent elements. High-quality equipment quickly responds to the appearance of primary signs of a fire.

Unreliable settings often result in false signals. Each licensed organization determines the scope of work and forms the total cost.

Payment depends on many factors:

1. area of ​​the premises;
2. type of system installed at the facility;
3. its level of complexity;
4. branching;
5. control method: automatic or manual;
6. electro characteristic installation work;
7. additional material costs.

Conclusion

Installation of fire alarm elements has its own characteristics. Before you start installing the system, it is important to determine its type and complexity of design. This depends on the equipment and equipment costs. These types of work are performed by licensed organizations employing qualified designers and engineers.

At home, you can independently mount a simple fire alarm. Any installation of the system is carried out in accordance with the regulations and requirements of GOST.

Functions and tasks of the OPS

A modern security fire alarm system is a highly efficient single system that operates offline. Installation of APS (automatic fire alarm) allows you to solve a whole range of security tasks a separate room or the whole building.

• Fire detection- the system, according to specific criteria, establishes the fact of a fire.
• Collection of information - the OPS collects the necessary data and records the processed information.
• Alarm generation- the system generates signals designed to notify everyone in the building about a fire.
• Turning on fire extinguishing systems– formation of commands for the activation of automatic means to eliminate fire and smoke.

Elements of the security and fire alarm

The OPS includes many high-precision instruments and technical means, combined into a single warning system. Depending on the type and purpose, the signaling may include various elements, however, the main functional units can be distinguished in each of them.

• Control system- this is the "brain" of the OPS, a central computer with specialized software. It is from this control panel that the settings of the entire system and the management of its elements are carried out.
• Sensors, annunciators and sensors– highly sensitive devices that capture control information various types. They record the fact of a threat (fire, unauthorized entry into the territory, etc.) and transmit the received data to the appropriate nodes.
• Data acquisition and processing equipment- points to which the primary information from the detectors arrives.
