The engine fire loop elements send their information to the FIDEEX control unit. The FIDEEX control unit in turn, sends information to the DAU. In the event of a fire, the DAU will signal the applicable engine fire DISCH handle to illuminate. The DAU reports the status of the detection system to the IAC which provides warning conditions to the EICAS and audio control panel.

FIRE PROTECTION
APU COMPARTMENT FIRE DETECTION
The APU fire protection system provides a means for detection of a fire condition within the APU enclosure. The APU uses the left or right fire bottle located in the aft fuselage section. Pulling the APU fire handle will signal the APU FADEC unit to initiate APU shut down. Turning the handle will discharge the selected fire extinguisher bottle.
On the ground, the FADEC will automatically shut down the APU if a fire signal is received for at least 5 seconds and the APU fire handle is not pulled. Although the APU will automatically shut down if a fire is detected, there is no automatic discharging of the fire extinguishing agent. Therefore, the APU must not be left unattended for ground operations.
The APU fire detection is self contained within the APU compartment. The detection system consists of the following:
.
Fire loop elements inside the compartment for fire detection.
.
Flight deck indication (red) through the fire handle and shut down signal to the APU FADEC.
.
Aural fire warning on the flight deck.
.
Automatic APU shut down on the ground, if necessary.
DUAL LOOP SENSING ELEMENT
STRUT SENSING ELEMENT
GF0910_017
The APU fire detection is provided by a dual loop system; each loop consists of sensing elements. Two element pairs are mounted directly to the airplane structure and the other element is mounted to a support tube.

APU COMPARTMENT FIRE DETECTION (CONT'D)
The APU compartment is protected by a two shot fire extinguishing system. Each discharge is independently directed by the pilot, with provision to guard against accidental discharge of both extinguishers into the APU.
APU LOCK RELEASE PIN
DISCH 12
PULL
GF0910_018
On the APU fire handle assembly, there is an additional lockout release pin located on the front panel. This release pin must be moved in conjunction with twisting the handle in order to discharge a second shot into the APU. The additional step for the APU is deemed necessary to preserve one shot for possible engine fire.
