- programming of parameters of signaling loops;

- 1224V voltage in each signaling loop;

- adaptation to the reactive resistance of the alarm loop;

- two-wire RS485 interface.

The standby power supply to the "Signal 20P SMD" receiver and control panel "S2000 M" is supplied from a separate uninterruptible power supply "BIRP12/4.0" with two automatic batteries with a capacity of 7 Ah.

Fire alarm devices and detectors are accepted in accordance with the "List of technical means of automatic fire extinguishing and fire alarm, having received certificates of compliance in GOST-R Certification Systems and certification of products and services in the field of fire safety"

The following types of fire detectors are used for fire detection:

- automatic smoke fire detector IP2donbass 1M;

- IPR-I manual fire detector.

Smoke detectors provide control in premises where smoke is the primary factor of the fire.

Smoke fire detectors, when installed on the ceiling, shall be located:

a) If the ceiling height is less than 3.5 meters:

- from wall to detector not more than 4.5 meters;

- between detectors not more than 9 meters.

b) At ceiling height from 3.5 to 6.0 meters:

- from wall to detector not more than 4.0 meters;

- between detectors not more than 8 meters.

IPR-I manual fire detectors are installed on escape routes at a height of 1.5 meters from the floor level, based on the condition that within 0.75 meters of it there are no other controls and objects preventing access to the detector, and the distance between detectors does not exceed 50 meters.

The distance from the detectors to the heat radiating devices shall not be less than 0.5 meters.

In case of parallel open laying, the distance from wires and fire alarm cables with voltage up to 60 V to power and lighting cables shall be at least 0.5 meters.

Wiring of alarm loops in the premises of the object is performed by wire KSPV 2 * 0.5 mm in PVC duct or corrugated PVC pipe D = 16 mm.

Warning and evacuation management system.

The fire warning system is designed to alert people about a fire and indicate escape routes. The audible alarm is started automatically when the fire alarm is triggered from the relay of the instrument "Signal 20P SMD." " The total number of sounders installed in the building is 8 pcs.

In the sound notification annunciators the okhrannopozharny sound "Svirel12" released by LLC AvroraBiNiB Volgograd are used.

Evacuation management system based on:

Light annunciator "BlikS12," produced by SvetlanOptoelectronika CJSC, St. Petersburg

Algorithm of the system operation.

The fire alarm system is on standby around the clock.

At operation of one smoke fire detector of alarm loop, "Signal 20P SMD" device transmits "Fire" signal. The corresponding information is transmitted and displayed on the graphical plan of the Automated Workstation, or on the C2000 M monitoring and control panel, after which the device "20P SMD Signal," by switching relay contacts, turns on the fire warning system.

When one manual fire detector is activated, the "Fire" signal is immediately transmitted and the fire warning system is activated.
