The AD913 allows communication between a Tecpro wired system and a simplex radio system, typically a pair or more of Walkie-talkies. It allows audio on the wired comms system to be transmitted to remote radios, and replies from these remote units to be heard by parties on the wired system circuit.
The unit provides a mic level output for connection to a transmitter and has a phone level input to accept a receiver. In addition it has arrangements to provide a push-to-talk (P.T.T.) or transmit on switching, operated by the signal lamp of outstations on the wired circuit to which the AD913 is connected. Any outstation can activate a radio transmission by depressing the signal lamp switch. The system signal lamps on other outstations will light in the normal way, and the speech on the wired circuit will be sent to the transmitter and the necessary transmit will be activated. All stations will hear incoming calls when the signal is off.
