Design solution. Fire extinguishing in manual and autonomous start-up modes
Structure of the system:
|No.||Modifications of UPSP||Use|
|1||Generator of fire extinguishing aerosol GEA «Doping-2.160p»||
|2||Manual start button PATS||
In the fire-hazardous compartments (engine compartment, heater compartment) of the vehicle, GEA «Doping-2.160p» is installed. Starting wires are laid in the driver’s cab and displayed on the start button of the PATS.
GEA «Doping-2.160p» can trigger itself from the thermo-start cord (self-service mode), or when the PATS button is pressed by the driver, in case of visual detection of a fire.
Limitations on the functionality of the kit:
- visual detection of a fire by the driver (only by external signs). GOA «Doping-2.160p» in this situation will fire one at a time, as the fire spreads. Since «Doping-2.160p» is a means of volumetric quenching, a single operation of GOA, if installed more than one, may not create the necessary extinguishing concentration and not extinguish the fire that has arisen;
- there is no constant control of the start loop of GOA «Doping-2.160p». If the starting wires are disconnected from the PATS button to GOA, when the driver’s start button is turned on, the «Doping» will, of course, not be started.
Recommended area of application:
- engine compartments of cars, minibuses, PAZ buses, etc. Objects on which a fire arises in the immediate vicinity of the driver. Accordingly, the automatic fire detection and extinguishing system is redundant in this case.
