3.3. Purpose and operation principle of APCP and CO unit.

Automatic installation of powder fire extinguishing is designed to detect the source of fire (fire) when temperature rises and smoke occurs in the premises of the building and to output the corresponding information to the panel of the SondSI PPKOP control and reception device to the duty room located on the ground floor.

In the event of a fire in the protected premises of the garage complex, heat or smoke fire detectors are triggered. Also, a fire signal may be received when the manual fire detector is activated.

Signal on detector actuation is transmitted via wired lines of signalling loop to MSS8 module serving eight signalling loops (SBS), and then via cable to panel of receiving and monitoring floor-by-floor devices "SondSI" installed in the duty room on the 1st floor with round-the-clock stay of duty personnel.

Panel of PPKOP "SondSI" receiving and control device provides actuation of fire warning system through relay on power supply module (MP), provides disconnection of supply and exhaust ventilation and actuates Tungus-6 powder fire extinguishing module in the corresponding direction.

Each MSHS8 module has two relay outlets, one of which controls the ventilation fire valve (from the smoke protection system) installed on the floor where the MSHS8 module is installed. Actuation of these systems is carried out when the detector in the loop is activated twice, which is accordingly provided by the installation programming.

Based on the characteristics of the rooms equipped with automatic fire alarm, the type of fire load and the use of substances and materials, the fire hazard category of the rooms, the design provides for the protection of machine boxes and all other rooms (offices, utility rooms, locker rooms, etc.) with thermal and smoke detectors, which are an effective means for detecting the fire center.

On the escape routes on each floor near the staircases or directly at the exits from the floor, manual fire detectors of the IPR 5132 type are installed at a height of 1.5 meters from the floor level.

The area controlled by one fire detector, as well as the maximum distance between the detectors, as well as the detector and the wall, comply with the requirements of NPB 882001 * "Fire extinguishing and alarm installations. Design Codes and Regulations. "

In accordance with the requirements of NPB 10403 "Warning and Evacuation Systems for Fires in Buildings and Structures," in the corridors of each floor of the garage complex building, a sound and light warning system for people in case of type 3 fire is provided. The number of alerts, their arrangement and power provide the necessary audibility in all places of possible stay of people.

The fire warning system is activated when the automatic fire alarm is triggered. At the same time, sound annunciators are activated on all floors of the building when fire detectors are triggered or a manual fire detector is activated. Electrical evacuation indicators "Exit" are installed on the escape routes according to the design of electrical lighting of the building, which, according to the requirements of paragraph 3.13 of NPB 10403, are in the ON state together with the main lighting devices of working lighting.
