Cargo Compartment Fire Extinguishing
[Option – 180 min protection]
Five fire extinguisher bottles are installed for cargo compartment fire
extinguishing. Pushing the FWD or AFT CARGO FIRE ARM switch (ARMED
visible) arms the extinguishers.
[Option – 180 min protection]
In flight, a fire warning from the cargo fire detection system causes the immediate
total discharge of two extinguisher bottles into the affected compartment. After a
15 minute time delay, the remaining three extinguisher bottles discharge at a
reduced flow rate into the affected compartment. If the airplane lands within the
15 minute time delay, only one of the remaining bottles discharges at the reduced
rate on touchdown.
In flight, pushing the CARGO FIRE DISCHARGE switch also activates the
extinguishing system.
On the ground, if a CARGO FIRE DISCHARGE switch is pushed, three
extinguisher bottles discharge simultaneously into the selected compartment, with
the third bottle discharging at a reduced flow rate.
When cargo fire extinguisher bottle discharge is initiated and the first two
extinguisher bottles begin to discharge:
• the CARGO FIRE DISCHARGE switch light illuminates
• the EICAS advisory message BOTTLE DISCH CARGO is displayed
