PROTECTION SYSTEM
BAGGAGE COMPARTMENT SMOKE DETECTION
SYSTEM
A smoke detection system is provided in the baggage compartment.
The system consists of two smoke detection modules installed on the
compartment ceiling.
A warning message is presented on the EICAS to indicate smoke
detection inside the baggage compartment and this message
disappears when the smoke is no longer present.
The smoke sensor resumes normal operation when the fire is
extinguished, the smoke has been cleared or the smoke sensor is
reset. On airplanes equipped with JAMCO (PN PU 90-431R1)
detector, the smoke sensor may also be reset through the power-reset
button, located on each smoke detection module.
Flight crew inspection of the baggage compartment is possible for
airplanes equipped with an optional sight glass in the rear lavatory
partition. For some airplanes a switch is available to turn on the lights
in the baggage compartment (Refer to 2-06-15 − Lighting).
BAGGAGE COMPARTMENT FIRE EXTINGUISHING
SYSTEM (OPTIONAL)
Two fire extinguishing bottles are installed in the rear electronic
compartment for baggage compartment fire protection.
The High-Rate Discharge Bottle is designed to instantaneously fill the
baggage compartment while the Metering Discharge Bottle provides
the required level of fire extinguishing agent concentration for at least
50 minutes.
Two smoke detectors are installed in the baggage compartment. Upon
smoke detection inside the baggage compartment, either one or both
smoke detectors send a signal to deactivate the baggage
compartment fan and illuminate the baggage fire extinguisher button
on the Fire Detection/Extinguishing Panel. When smoke is no longer
present, the baggage compartment fan is reactivated and the baggage
fire extinguisher button light turns off.
