ABSTRACT:
A smoke detector unit with a fan that creates an airstream which flows through a smoke detector. Both the fan and the smoke detector are located within a housing that is mounted to the fuselage of an airplane. The smoke detector generates an output signal that is provided to an indicator when a threshold level of smoke is detected. The output signal is typically latched by a relay that is also located within the housing.
