ABSTRACT:
An apparatus is provided for communicating to a transmitter or sender of an emergency message a response indicating that the message was received. The apparatus operates in conjunction with a portable transceiver alarm unit carried by the sender, a continuous-loop magnetic tape recorder-player unit, and a local CB radio (i.e., a CB radio located within the range of the portable transceiver alarm unit). In response to a signal from the portable alarm unit, the apparatus activates the recorder-player causing it to play a pre-recorded emergency message and to apply this message, in the form of a message signal, to the local CB radio. The local CB radio transmits the message to a listener at a remote CB radio station. In response to a selected acknowledgement message received from a listener via the local CB radio, the apparatus detects the acknowledgement message and transmits a signal to the portable alarm unit indicating receipt by a listener of the emergency message. The apparatus includes a transceiver, a power supply unit, an interface unit, and a listening circuit.
