Fire alarm of a residential building

General Instructions

These working drawings of the automatic fire alarm system are developed on the basis of architectural and construction drawings of LLC Studio of Architecture and Design.

The work project has been completed in accordance with the requirements of:

- NPB 882001 "Fire Safety Standards";

- NPB 10403 "Design of fire warning systems for people in buildings and

weapons;

- NPB 11003 "List of buildings, structures, premises and equipment subject to

protection by automatic fire extinguishing and automatic fire fighting units

signalling ";

- SNiP 2.01.0189 "Residential buildings."

To detect the source of fire at an early stage, the project provides

installation of autonomous optoelectronic fire smoke detectors of type IP2¼ 0UB in living rooms, bedrooms and kitchens of apartments. In hallway apartments, on sites, in built-in

smoke optoelectronic detectors of type IP 21245M are installed in new premises for office and commercial purposes. Manual fire detectors of IPR-K type are installed along evacuation routes at exits from the floor at a height of 1.5 m from the floor level.

For the notification about the fire and designations of exits are used the light-sound boards of NBO2h1 "Exit" established on each floor at an exit to a ladder.

As equipment for receiving signals from detectors, receiving and control devices of the type "Signal20P" (for the residential part of the building) and "C20004" (for the premises of the 1st floor) were adopted.

Control is exercised by means of the C2000 remote controller, and events in a system are displayed on the block of indication "S2000BI". Signal-start units "C2000 SP1" are used to issue a command for control of smoke removal valves.

RS485 interface loops connecting devices of this system are executed

KPSVEV 2h2h0.5 cable. Address loops are made by 2x0.5 KSPV cable and are output

on KRTP10h2 boxes installed in floor SR. From boxes to control boxes

10x0.5 KSPV cable is laid for instruments.

Connection of light-sound boards is executed by a wire of ShVVP2h0.75.

For structural diagram of fire alarm refer to Sheet 2.

Power supply of the fire alarm system is carried out from the ~ 220 V network and

Skat2400R20 uninterruptible power supply units in an inhabited part of the building and "RIP12" in

a store and offices. Uninterruptible power supplies ensure system operation during

24 hours in standby mode and at least 3 hours in "Fire" mode.

Connection of the designed equipment to the ~ 220 V network is made in the EM package.

In an inhabited part of the building equipment ("Signal20P"", C2000"", S2000BI"", S2000-SP1"

"Skat2400P20") to be installed on the 1st floor in the cleaning equipment room. Indoors

store and offices location of equipment ("S20004," "S2000-SP1," "RIP12") to clarify

in place.
