DESCRIPTION AND OPERATION

1. Purpose

A. The fire extinguisher stores fire extinguishing agent under high pressure. When the sensors indicate smoke, the pilot operates a control switch sending an electrical signal to the cartridge mounted in the discharge outlet (see Figure 1). This causes the cartridge to detonate, which fractures a rupture disc and releases extinguishing agent to extinguish the fire.

2. Description

A. The fire extinguisher is a spherical, stainless steel container (see Figure 2). Its primary components include:

• Container weldment

• Fill fitting

• Pressure gauge and switch

• Two rupture discs

• Two discharge outlets

• Two cartridges

B. The weldment is an all-welded stainless steel shell, which includes mounting lugs and fill, discharge, and switch bosses. The fill fitting and rupture discs are welded to their bosses.

C. The fill fitting is used to fill the weldment with the extinguishing agent. The fill fitting incorporates a stainless steel disc that acts as the primary safety relief device.

D. A pre-stressed stainless steel rupture disc is welded inside each discharge boss. The rupture disc fractures to release the extinguishing agent when the cartridge is detonated.

E. The discharge outlet is a flow path for the extinguishing agent and the mounting bed for the explosive cartridge. A screen inside the discharge outlet keeps the cartridge debris from entering the discharge line. The discharge outlet is safety wired to the weldment for a secure installation upon installation on the aircraft.

F. The explosive cartridge is the detonation force necessary to fracture the rupture disc. The cartridge is safety wired to the discharge outlet and caution tagged for safety.

G. The pressure gauge and switch permit monitoring of the charge pressure to determine if extinguishing agent has leaked from the weldment or if the fire extinguisher has been discharged.

H. The fire extinguisher is shipped with protective caps to cover the discharge outlet and the fill fitting. The protective cap, installed on the cartridge, shields the firing circuit from electromagnetic interference.

26-22-30 Page 1May 01/14


3. Operation

A. To release the extinguishing agent, the pilot operates a control switch, applying 18 to 36 VDC, 3.5 amperes current (for P/N’s 33700002 and 33700006-1) or 17 to 36 VDC, 3.5 amperes current (for P/N 33700005) to the cartridge connector pins. The current detonates the explosive charge in the cartridge. The explosion creates a shock wave, which fractures the rupture disc and releases the extinguishing agent into the discharge line.

B. The pressure gauge and switch should be checked regularly to make sure that the fire extinguisher is charged.
