Abstract
A system for transmitting data between a subscriber site and at least one monitoring station, comprising a sensor circuit for generating data responsive to an event at the subscriber site, a first transmission circuit responsive to said sensor circuit and being operable to transmit data in a first format from the subscriber site to the monitoring station over an RF telecommunications network, a second transmission circuit responsive to said sensor circuit and being operable to transmit data from the subscriber site to the monitoring station over a second telecommunications network. A programmable converter module converts between an alarm signal format and an RF cellular technology format.
