In this case, when determining the number of detectors, the combined detector is taken into account as one detector.

13.3.16. Floor-mounted detectors can be used to protect the area below a perforated false ceiling if the following conditions are met simultaneously:

The perforation has a periodic structure and its area exceeds 40% of the surface;

The minimum size of each perforation in any section is at least 10 mm;

The thickness of the false ceiling is no more than three times the minimum size of the perforation cell.

If at least one of these requirements is not met, the detectors must be installed on the false ceiling in the main room, and if it is necessary to protect the space behind the false ceiling, additional detectors must be installed on the main ceiling.

13.3.17. The detectors should be oriented so that the indicators are directed, if possible, towards the door leading to the exit from the room.

13.3.18. The placement and use of fire detectors, the procedure for the use of which is not defined in this set of rules, must be carried out in accordance with the recommendations agreed upon in the prescribed manner.
