7 Condensed Aerosol Generator Description
7.1 General Description of the Aerosol Generator Units
The range of condensed aerosol generators is shown in the appendix “B”.
The condensed aerosol generator is formed by the following main components:
7.1.1 The Solid Aerosol-Forming Compound FPC:
The solid aerosol-forming compound FPC is the originator of the condensed extinguishing aerosol
(generated by the FPC activation):
Upon actuation, the solid aerosol-forming compound FPC will undergo a combustion reaction
generating the fire extinguishing condensed aerosol.

7.1.2 The Ignition Device (Initiator):
FirePro Xtinguish
condensed aerosol generators are initiated by applying the appropriate voltage
across the electric wire terminals of the aerosol generator so that the solid aerosol forming compound
will be activated and transformed into the condensed aerosol (the extinguishing agent).
7.1.3 The Cooling Mechanism:
FirePro Xtinguish
condensed aerosol generators are equipped with a physical heat-absorbing
mechanism (the cooling mechanism). The generated aerosol will exit the generator via the cooling
mechanism, and the condensed aerosol will be cooled down before flooding the protected volume.
