FIRE EXTINGUISHER BOTTLES
Figure 1
WARNING: THE FIRE EXTINGUISHER BOTTLES ARE PRESSURIZED CONTAINERS AND UTILIZE AN
EXPLOSIVE CARTRIDGE. Extreme care must be taken when handling the fire extinguisher
bottle and cartridge assemblies to prevent accidental firing of the cartridge. Injury to personnel
and/or damage to equipment can result.
NOTE: The fire extinguisher bottles must be replaced at the interval specified in Chapter 4.
The fire extinguisher bottles are mounted forward of the respective engine firewall (Zone 581 left and 681 right).
Each 90 cubic-inch fire extinguisher bottle is charged with 3.00, + 0.25, - 0 pounds of Bromotrifluoromethane
(CBrF3) super pressurized with 600, + 0.25, - 0 psig of Nitrogen (N2) at 70°F. The fire extinguisher bottle is fired by
detonation of an explosive cartridge on the fire extinguisher bottle head. Once a fire extinguisher bottle cartridge is
detonated, the entire supply of extinguishing agent is discharged from the fire extinguisher bottle. A fill and safety
relief valve is located on the fire extinguisher bottle. The safety relief valve releases pressure from 1520 to 1700 psi
at 200°F. For components of the fire extinguishing test system, refer to FIRE EXTINGUISHING SYSTEM
OPERATIONAL TEST.
FIRE EXTINGUISHER ACTUATOR CARTRIDGE/SQUIB
Figure 1
WARNING: The cartridge/squib is a pyrotechnic device. Inadvertent detonation of the cartridge can cause
personnel injury. For safe handling, the electrical connector must be disconnected and a
plastic protection cap installed on the cartridge/squib electrical connector.
NOTE: The cartridge/squib must be replaced at the interval specified in Chapter 4.
The fire extinguisher actuator cartridge is electrically fired providing a method of controlling the release of the
fireextinguishing agent. When actuated, the cartridge produces high energy pressure to rupture the housing
assembly, removing the restraining force from the discharge valve plug. The pressurized extinguishing agent
unseats the plug, releasing extinguishing agent through the deployment tubes to the nacelle discharge ducts.
