Modular automatic fire extinguishing units

Automatic water fire extinguishing modules YaTRV1Ex manufactured by ERVIST Company LLC and powder fire extinguishing modules Opan100 and Opan50 manufactured by Technomash LLC were used as automatic fire extinguishing units.

MPTRV of YauzaTRV1Eh consists of the tight steel casing filled with water with surfactant additive and two gas-generating elements established in special boxes in the case. In the lower part of the module body there is a flange on which a bursting membrane and a nozzle sprayer are installed, which includes five sprinklers and is equipped with a filtering element.

WFP Opan100 (50) consists of a cylindrical housing filled with fire extinguishing powder and a gas generating device located inside the housing in the powder thickness.

The units are designed in accordance with the requirements of sections 9, 12.4, 14 of SP 5.131302009.

MPTRV of YauzaTRV1Eh applies to fire fighting of classes A and B in accordance with GOST 27331, MPP Opan100 (50) - to fire fighting of the classes A, B, C, D, E, and are applied in automatic modular installations of fire extinguishing to protection of all area or local protection of production, warehouse, administration, archival premises, storages of museum values and exhibitions, mines, including dangerous on firedamp.

The project at the protected facilities provides a 100% supply of MPRV YaTVEx and fire extinguishing agent for WFP Opan100 (50).

Fire extinguishing modules with finely sprayed water are suspended on the roof in the center of the VM chamber.

Powder fire extinguishing modules are installed on the soil with mandatory rigid attachment in designated places.

Are established by PPKUP of "PPU4I" on the side surfaces of developments in the allocated places.

Remote start-up panels are installed at evacuation exits outside the protected area and serve for remote start-up of the unit.

To disable automatic control of fire extinguishing during the presence of people at the entrances to the protected areas, button posts "Disable automatic fire extinguishing start" are installed.

Fire detectors are installed on the working roof. In electric locomotive depots, the main factors of the fire are smoke release and flames. At the same time, in view of the content of dust particles in the air of underground structures, the use of optical (reacting to smoke or flame) detectors is not advisable. Thermal explosion-proof threshold detectors "IP1019A3/60 (P)" are used as detectors, performing the following functions:

detection of temperature threshold value;

low probability of false alarm;

continuous 24/7 operation.

As a means of warning about fire and fire extinguishing systems in the underground part of the protection object at the exit from the protected area, a light and sound annunciator and a light annunciator "Leave powder" are used; "Powder do not enter" and "Automation is off" light annunciators at the entrance to the protected area; in the direction of movement to the exits from the protected area - "Direction of movement to the exit" light-and-sound annunciators

Principle and operating modes of modular automatic fire extinguishing plants

In accordance with SP 5.131302009 "Fire protection systems. Fire alarm and fire extinguishing units are automatic. Design Codes and Regulations "automatic fire extinguishing plant control equipment provides the following functions:

sending a signal about the plant actuation to the control room of the mining dispatcher;

automatic monitoring of starter control trunks and starter circuits for short circuit and break;

remote start-up of fire extinguishing systems from the control room of the mining dispatcher;

Normal mode

"Normal" mode is the standby mode corresponding to the system state:

PPPCS power supply from the main power supply;

serviceability of loops;

alert condition of detectors.

In standby mode, the plant continuously monitors its operability, recharges built-in batteries and interrogates fire detectors.

Heating mode

The unit sets to "Heating" mode when one automatic fire detector is activated. The "Heating" signal is transmitted to the receiving control device installed on the protected object. The panel in the control room receives the signal "Heating" with the display of the protected object in which the fire detector was activated.

"Fire" mode

In the "Fire" mode, the plant switches over when two automatic fire detectors are activated, as well as when the remote launch panel installed at the entrance to the protected room (outside) is activated. Contacts of "Fire" relay are switched over. A signal "Fire. The panel in the control room receives a signal "Fire" with the display of the protected object in which the fire detectors worked. Light-and-sound annunciators of the warning and evacuation control system are turned on.

When "Fire" signal is received, PPKPC generates control pulse to start MPRV without delay, to MPP with delay of 30 s. At the same time, a sound signal is turned on in the protected camera.

In case of visual detection of fire, the duty personnel can remotely activate the fire extinguishing system from the PPU4I device or remote launch panel installed at the outlet outside the protected chamber.

"Emergency" mode

In "Emergency" mode, the unit sets to:

in case of a break or short circuit in the fire alarm loop;

receiving a signal about failure of controlled external devices;

if PPPKUP fails, at that further operation of the unit is blocked.

Contacts of relay "Emergency" are switched over.

"Manual start" mode

The unit sets to "Manual start" mode at pressing of "Stop automatic fire extinguishing start" button post. At the same time, the system continues to monitor the protected area for fire, as well as lines for a break and short circuit. When "Heating," "Fire" signals are received, signals are generated to the dispatcher console, and the warning system is activated. Fire extinguishing modules are not started.

Interconnection of automatic fire extinguishing systems with other systems and engineering equipment of facilities

The interconnection of automatic fire alarm systems and automatic fire extinguishing systems with other systems and engineering equipment of the facilities is provided in accordance with the requirements of s.14 SP 5.13130.2009.

Generation of signals for automatic control of fire extinguishing units is carried out when two fire detectors are activated, which are switched on according to logic "I." To implement this requirement, at least 3 automatic fire detectors are installed in each protected chamber, the distance between which is not more than half of the normative one. The distance is determined in accordance with the note to item 14.1 of SP 5.13130.2009.

When automatic fire alarm and/or automatic fire extinguishing units are activated, the following command pulses are output:

to start the warning and evacuation control system in case of fire;

for shutdown of process equipment.

For realization of command impulses contacts of the relay of the PPU4I device and ETPPSO remote controller 3.10 are used
