An alarm system for a protected premises includes an alarm sensor for generating an alarm signal in the event of an alarm condition. A cellular-type radio/telephone transceiver is located at the protected premises and includes circuitry for generating and transmitting a unique identification number of the transceiver and a send signal for wireless communication with a cellular site. Structure is provided for connecting the alarm signal line to the cellular-type radio/transceiver such that upon receipt of the alarm signal, the cellular-type radio/transceiver will transmit the unique identification number and the send signal to the cellular site with no transmission of the telephone number of an alarm monitoring station to thereby enable the cellular site to transmit the alarm condition to the alarm monitoring station.
