Description
Fire protection for the baggage compartment consists of an electronic smoke detector that
interfaces with the EICAS to provide aural and visual warnings.

smoke density reaches a predetermined level, the smoke detector produces a fire warning
signal, which causes the following aural and visual warnings to occur:
• SMOKE BAGGAGE BAY warning EICAS message is displayed;
• MASTER WARNING switch/lights illuminate flashing; and
• “SMOKE” aural warning sounds.
The aural warning can be silenced by pressing either MASTER WARNING switch/light.

EICAS to provide aural and visual warnings, and an independent fire extinguisher that operates
automatically in the waste container.
Components and Operation
Smoke Detector
The aircraft is equipped with a smoke detection system in the lavatory. When the smoke density
reaches a predetermined level, the smoke detector produces a signal to the EICAS to alert the
crew, and sounds an aural alarm in the lavatory. The lavatory smoke warning signal causes the
following aural and visual warnings to occur:
• SMOKE TOILET warning EICAS message is displayed;
• MASTER WARNING switch/lights illuminate flashing; and
• “SMOKE” aural warning sounds.
The aural warning can be silenced by pressing either MASTER WARNING switch/light.
However, the EICAS warning message will remain displayed until the unit resets itself.
Automatic Fire Extinguisher
In the event of a fire in the lavatory waste container, automatic fire extinguishing is provided.
The bottle is mounted on a bracket beside the waste container. Once the temperature reaches a
predetermined level, two heat-sensitive capsules melt, and release Halon 1211 into the waste
container (individual aircraft installations may vary, consult Completion Center documentation
for aircraft-specific information).
