FIRE SUPPRESSION
The fire extinguishing system is made up of a fire extinguishing cartridge and
associated delivery tubing and wiring. A pressurized fire canister with a pyrotechnic
discharge cartridge is installed in each engine pylon.
Figure 116. Fire Extinguisher Canister Location
The fire extinguishing system delivers the PhostrEx™ extinguishing agent to the
engine by a tube and nozzle located inside the nacelle and aimed to provide
maximum dispersion.
The fire extinguisher is a single shot system, dispersed by an electrical charge that
activates an explosive squib in the fire extinguisher canister releasing the agent
under pressure. Rigid tubes convey the suppression agent to the nacelles, where it is
injected via nozzles located on the firewalls. The agent eliminates oxygen in the
nacelle and extinguishes the fire. Each fire canister is controlled independently from
the other and has a dedicated switch/indicator.
The fill level should be in the green band indicated on the canisters which can be
seen through clear windows in the top of each pylon.
