Abstract
A method and system for responding to security system inoperability due to damage of a telecommunications line interconnecting the security system to its central monitoring service system requires origination of a wireless telephone call. A wireless unit is interconnected to the security system and originates an emergency call upon detection of telecommunications line abnormalities. Upon establishing a call connection between the wireless unit and the central monitoring service system, the wireless unit relays dual tone multifrequency (DTMF) signals which identify the security system affected by the breach so that appropriate authorities may be dispatched. In alternative embodiments, the wireless unit is programmed to place calls to other designated telephone numbers.
