Multiplexing and Monitoring Unit BKK-1


The mutiplexing and monitoring unit is designed for computer-aided ground operation test of the aircraft fire protection systems (for Tu-204, Tu-214, IL-96, IL-114, An-70) as well as for propagation and sending of emergency signals (in flight) from the fire protection system to the nominal on-board means of visual inspection and recording of emergency information.


In flight, the BKK -1 unit propagates and sends the emergency signals to the fire protection system’s panel, emergency flight recorder (“black box”), information systems, central signal light and voice alert system.
