Abstract
An alarm system has an alarm unit in combination with a line seize module. The alarm unit includes a transmitter/receiver, a control panel function, a key pad, an input/output port connected to a telephone line and an auto dialer for normally communicating with a remote monitoring station over the public switched telephone network. The line seize module includes an input communication port connected to the telephone line, a signal transmitter and receiver for communication over telephone wiring with the alarm unit, control logic, a line seize arrangement and an automatic dialer. Control logic processing signals are received by the input port. The line seize module, upon receiving an alarm signal from the alarm unit, reports the signal to a remote monitoring station using the automatic dialer and the public switched telephone network.
