The semaphore unit provides a combination of socket output facility and fixed lighting by means of 2 x 2ft 40 watt safetylites mounted on adjustable arms on the rigid or adjustable centre pole fixed to the main enclosure.
All electrical components are housed within the sealed enclosure and all sockets are switched interlocked and circuit breaker protected. The semaphore units are supplied with power from the main distribution units, festoon boxes or other semaphore units via a 3 core PVD insulated screened cable and fused plug.
The service access is achieved by removing the unit from its stand and releasing the hinged base. The main advantage of the semaphore unit is when the aircraft cabin lights are inoperative or lighting is required around the landing gear or engine areas and general lighting is essential.
