Main Design Solutions

The adopted technical solution is based on an integrated approach to fire protection of the residential part of the building. Automatic fire alarm provides early detection of a fire in apartments, in out-of-apartment corridors, in halls, in the garbage collection chamber and sends address signals to the systems: alerts and evacuations of people, smoke removal and other engineering systems that ensure the safe presence of people in the building in emergency and extreme situations.

In each room of apartments, autonomous smoke fire detectors are installed in accordance with NPB 66, taking into account the closure of the area by one detector of no more than 20m2 IP 21243M, in the design on floor plans the detectors are not shown, they are taken into account in the specification.

The residential part of the building is equipped with automatic fire alarm:

public places (MOS) - halls, out-of-apartment corridors, smoke fire detectors IP 21249AM;

front apartments - heat fire detectors IP 1035/21A and manual fire detector IPR-I (addressing of 2 apartments);

by escape routes in PC box - IPR-I address manual fire detectors;

installation of ISP UOS2k on fire cranes (addressing of the floor crane);

concierge room (smoke fire detectors);

garbage collection chamber (smoke fire detectors);

on the ground floor there are light-and-sound fire alerts "BlikZS24" FIRE ";

AC24 sound fire annunciators are located on each floor.

Detectors designed for automatic actuation of fire-fighting automation are located according to the backup system in accordance with NPB 882001 *.

Signal for actuation of "FIRE2" automatics is generated in the following cases:

Automatically:

actuation of at least two automatic fire detectors in the front apartment;

actuation of at least two automatic fire detectors in out-of-apartment corridors;

actuation of at least two automatic fire detectors in the concierge room;

Remotely:

actuation of the manual fire detector in the fire crane cabinet on each floor;

actuation of the manual fire detector installed in the apartment.

When the signal "Fire 2" is received, the SCP generates address control signals to the fire automation control system (using pre-programmed logic) due to the control modules and relay of the device, namely:

switching on smoke removal systems (opening of smoke removal valves and switching on smoke removal fans) on floors and sections separately;

lowering elevators to the first landing floor ;

activation of fire warning and evacuation systems in the section;

actuation of air pressure systems;

"Fire" signal on the ODS;

"Fire" signal to PCP.

When smoke removal and air overpressure systems are switched on, a signal is transmitted to the ODS about automatic switching on sections separately;

Generation of signal for starting of fire-fighting water supply pump is output at opening of floor fire valve automatically from ISP US2k.

When automatic detectors are triggered on different floors, automation is not activated.

If no PCP is used, relay 3 and 4 of the device shall be programmed to "Fire 2" to transmit "FIRE" signal to the ODS in the second section.

Principle of Fire Protection Automation Operation and Interaction of AUPS with Other Systems

When smoke occurs in out-of-apartment corridors, halls in the residential part of the building, or when the maximum temperature in the apartments is reached, automatic fire detectors are triggered. When one detector operates in the protected room, the device generates a signal "Fire 1." The LCD display shows "FIRE" and the exact fire location "1 section 5th floor," ″ Apartment No. 17 ″ or "2 section 8th floor," ″ Out-of-apartment corridor. " Fire control is not activated.

When two automatic heat detectors are switched on in the apartment or two automatic smoke detectors in the out-of-apartment corridors, as well as when IPR-I is turned on in the apartments or in the PC cabinet, the device generates a signal "Fire 2." At generation of "Fire 2" signal "FIRE" is displayed on LCD, the exact place of fire is indicated and the set time count for fire automation start is actuated.

In case of "FIRE 2" event on the corresponding floor, MA-U provides the command to open the AP. When the valve is opened, the end contacts (valve position control) are opened and the signal about the KDU opening is transmitted to the instrument. Information is displayed on the PCB display (DD valve 1 of floor 2 section is open).

The second signal is supplied to the MCU, which operates for alert control. Relay is closed in constant mode and 24 V is supplied to all AC24 annunciators.

The device sends the following commands to turn on the smoke removal system, air overpressure, and lowering the elevator.

When smoke removal and air overpressure systems are switched on, a signal is transmitted to the ODS to start automation in this section.

Relay 1 and relay 3 of the device are switched on and the "FIRE" signal is transmitted to the PCP and to the ODS.

If any fault occurs, contacts of relay 2 and relay 4 are opened and "Fault" signal is transmitted to PCP.

When opening the crane in the cabinet, the SCP outputs a signal indicating the exact floor where the signal came from and gives the command to switch on only the ECM, which sends the signal to the pumps.

Actuation of signal on ODS

To output the general signal "Fire" and "Fault" to the combined control service, connect the signal lamp installed in the control room to relay 1 and relay 2 of the device with 2x1.5 VVP cable.

The subtime of air and smoke removal are provided to remove signals of inclusion of systems from inclusion of PD and VD through HEY MA7TK and to transmit through MA-U a signal of turning on of automatic equipment in a certain section. The installation locations are shown in the equipment layout.

The above signals shall be generated by monitoring the open position of the intake valve, the air overpressure system and the operation of the fan starter of the smoke removal system. Signals about actuation of systems are output separately in the form of light warning in the control room.

Activation of fire pump

Generation of signal for fire pump activation is performed automatically from ISP US2k. Address tag of MA7TK, having accepted a signal from the announcer of SP UOS2k, transmits a signal of "POZhAR2" to PKP. The device gives the command of the UIA, which works to turn on the fire pump, to turn on the relay.
