LAVATORY FIRE PROTECTION SYSTEM
LAVATORY SMOKE DETECTION
The lavatory smoke detection system consists of a smoke sensor
installed in the lavatory ceiling and a Smoke Detector Panel located
near the forward galley.
Upon detection of smoke inside the lavatory, the smoke detector
signals the panel to activate a red alarm light and a horn. In addition, a
warning message is presented on the EICAS. The smoke sensor is
less sensitive to smoke from cigarettes.
The EMB-135 has an additional horn, installed in the aft cabin section
on the ceiling panel, right in front of the lavatory door.
LAVATORY FIRE EXTINGUISHING
A single fire extinguisher bottle is installed for fire protection of the
lavatory waste container.
The bottle discharging tube outlets are fitted to the waste container,
and are provided with temperature sensitive heads. Discharge of the
extinguishing agent is accomplished by sensitive heads melting under
high temperatures, which opens an outlet passage.
No warning is provided in the cockpit when the waste container
extinguisher bottle is discharged.
