BAGGAGE FIRE DETECTION SYSTEM - GENERAL
The purpose of the baggage fire detection system is to detect smoke in the
baggage compartment.
The system comprises a smoke detector installed in the baggage
compartment.
BAGGAGE FIRE DETECTION SYSTEM – MAIN
COMPONENTS
SMOKE DETECTOR
The smoke sensor is made by a photoelectric device that operates on the
light-scattering principle.
The detector alarms when the smoke concentration level exceeds a
predetermined level.
The device employs two light sensing and amplifying channels installed in
the baggage bay.
SMOKE DETECTOR – OPERATION
The reference channel senses the amount of light emitted by an internal
LED (Light Emitting Diode) source.
The smoke channel senses the amount of emitted light scattered by smoke
particles in the baggage.
The smoke detector alarms when the output from the smoke channel
exceeds a predetermined smoke concentration level.
