Almaz-UPM Audio warning system
Audio warning system designed for automatic replaying of the voice messages, which were recorded into the internal memory preliminary, warning (informing) the crew and, if required, ground services on the emergency, dangerous and other situations in the aircraft.
Voice warning system provides:
- recording and non-volatile storage of the voice messages, grouped into the sets (dictinaries) with the specofied priority, urgency and sign of the message receiver for each message;
- receiving of the commands for voice messages replaying activation from warning signal transducers of from aircraft computers;
- receiving of the enabling commands for specifying the logic of the messages replaying;
- receiving of the control commands (the messages breaking, repeating, deleting;
- listening to the messages; selection of the dictionary, etc.)generating and replaying of the voice messages to the crew (via intercom)and to the ground services (via airborne radio);
- entering of A/C registration number and its replaying before the messages, transmitted to the ground services;
- generating of the commands control for controlling the intercom and airborne radio when voice messages are generated.
