To discharge the APU bottle, the handle must be turned fully and held (at least one second) to overcome the spring force of the handle; counterclockwise (bottle 1) or clockwise (bottle 2). This action will send redundant commands to discharge the selected fire extinguisher bottle into the armed zone.
To discharge a second extinguisher bottle in the APU, the lockout release pin must be slid to the opposite position, to allow the handle to be rotated past the centre position. When a handle is turned fully in the opposite direction, the remaining bottle will be discharged.

FIRE EXTINGUISHER ASSEMBLY
The designated fire zones are left engine, right engine and APU. There are two fire extinguisher bottles on each airplane attached to the left rear fuselage structure. Each fire extinguisher bottle incorporates a hermetically-sealed pressure vessel filled with Halon 1301. The forward fire extinguisher bottle is designated as bottle 1 and the aft fire extinguisher is designated as bottle 2.

Fire Extinguisher Discharge Squibs
A fire extinguisher discharge squib (electro-explosive device) is installed in each fire extinguisher discharge port. Each of the three discharge squibs per extinguishing bottle is assigned to each of the three fire protection zones. The zones have two circuits, each of which is capable of firing the squib. One of the circuits is wired to channel A and the other to channel B of the FIDEEX control unit.
GF0910_009
A pressure alarm gage displays fire extinguisher pressure at the extinguisher and includes a pressure switch. The pressure alarm gauge automatically signals the FIDEEX control unit when the fire extinguisher pressure drops below the minimum operating pressure.
If one of the circuits detect a fault, it will report to Central Aircraft Information Maintenance System (CAIMS) and no EICAS message will be posted since there is no loss of bottle discharge capability. If both circuits to a squib are detected to be nonfunctional, a squib advisory message will be posted for the affected system.
