The systems of combined fire extinguishing СКП-А with automatic power-on
The systems of combined fire extinguishing СКП-А with automatic power-on consist of two independent lines: powder line with the device of automatic activation, intended for automatic electric switching or for manually activating of actuation mechanism of gas cylinder and solution line. These lines can be switched on separately or simultaneously. СП-А fire extinguishing systems with automatic activation are composed only of the powder line.
Powder line is designed for extinguishing in the engine compartment or another part by the throw of fire extinguishing powder in the points through the holes in the distribution pipe. Solution line is used for extinguishing fires outside the zone of protection of the powder lines, and for secondary fires by extinguishing solution in the fire.
The system automatically activates the actuation mechanism of the powder line when a heat detector reaches the temperature of activation in the protected area. At fire detection, switching of powder line as well could be activated by the operator with a pressing of electric start button on the board of the device of automatic activation, or on remote board, or with slap of the palm on hand-operated button of actuation mechanism. The solution line is driven manually.
I - the device of automatic activation; II - powder; III - the solution line
The device of automatic activation implements:
- light alarm of presence of electric power supply in the circuit;
- light alarm of malfunction of heat detectors, circuit of remote board and the circuit of generating start element (GSE);
- protection of device of automatic activation when short-circuit and over-voltage of external power source (the onboard circuit of the vehicle);
- backup power supply of automatic transfer switch for up to 5 days when disconnected from an external power source;
- control of changes of the temperature range in the area of heat detectors;
- sound and light alarms when the temperature reaches 100o C of the specific heat detector, and "(ПОЖАР)FIRE" upon reaching a critical temperature;
- automatic activation of powder line system upon reaching a critical temperature;
- emergency activation of the powder line with pressing an electric start button on the control board, or pressing it on the remote board, or with the button of hand start which is located on the shut-off control head.
