The systems of combined fire extinguishing with remote start control

The systems of combined fire extinguishing with remote start control consist of two independent lines:

powder line with remote start control, intended for electric remote start control or for manually activating of actuation mechanism of gas cylinder, and solution line. These lines can be switched on separately or simultaneously.

The fire extinguishing systems with remote start control 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.

Activation of powder line is conducted by a operator. The operator turns on actuation mechanism on a gas cylinder with a pressing of electric start button on the remote board, or on an external remote start control, or with slap of the palm on hand-operated button of actuation mechanism. The solution line is driven manually.

.

I - the remote board; II the powder line; III - the solution line;

The remote board implements:

  • alarm of presence of electric power supply in the circuit;
  • light alarm malfunction of circuit of the external remote start control and the circuit of generating start element (GSE);
  • activation of the powder line with pressing an electric start button on the control board, or pressing it on the external remote control, or with the button of hand start which is located on the shut-off control head.
