Abstract

A communication system (1) provides a wireless path for transmission of alarm signals from subscriber alarms systems (2) to monitoring stations (4) without transmission of a telephony signal from the alarm systems (2). No modification of the monitoring station (4) is required as the system (1) generates the telephony signal which the monitoring station expects to receive, even though only a trigger signal is transmitted. The system (1) may be used with a wide variety of different existing subscriber alarm systems (2) by appropriate connection of terminals on an interface (5) to conductors in the control panel of the subscriber alarm system (2). An acknowledgement is transmitted back as a "MIN Page" to the interface (5).
