FirePro Xtinguish Initiator (electrical activator)
The initiator is connected to the activation power circuit (minimum current required 0.8 A for 3 - 4
seconds) by heat resistant wires. The activation power will heat up the electric coil (4) thus the
(5) solid aerosol forming compound (FPC) will initiate an exothermal reaction. The heat developed
will transfer through the cylinder (7) outlets starting the exothermal reaction of the (9) FPC, thus
the thermal energy will be sufficient to start the reaction of the whole mass of FPC contained
inside the aerosol generator, transforming the FPC into a particulate aerosol and carrier gases.
