ASOTP “Needle-TPN” PA2
The automatic system for detecting and extinguishing fires “Igla-TPN” RA2 was developed for automatic detection and extinguishing of fires on traction rolling stock.
The peculiarity of this system is its flexibility in the configuration and the ability to work with various types of sensors and extinguishing means with an electric start, which makes it possible to apply it on one-, two- and multi-section vehicles using a powder, aerosol or combined fire extinguishing method. It is possible to duplicate communication lines to increase the survivability of the system and to enter an additional second stage of extinguishing. The system is successfully used on rail buses RA-2.
On each car are allocated protection zones. In the zones, fire alarm sensors and extinguishing agents are installed. Sensors and extinguishing means via communication lines are connected to the address local control unit (LBK), which monitors the fire-hazardous situation and the state of the equipment in the zone. If the protection zone is controlled by several LBK units, then they are combined into one zone.
LBK units are connected by wire communication lines to the intermediate control and monitoring unit (BKU), which in turn is connected to a dedicated train line to exchange information about the state of the system between the cars of the train. Block BKU in the event of a fire situation produces a signal to turn off the equipment on the car.
In the driver’s cab, the head cars of the train consist of control and display units (BKI). Block BUI is intended for delivery of the address information messages on a condition of system on structure, management of system and storage of archive of events in system.
The system is powered by the on-board network of the car with a voltage of 24 V.
