Abstract
A security system backup device which provides a system that recognizes when an outdoor telephone line near the building has been severed and provides a means by which a distress message can be sent over the operable part of the outdoor telephone lines. The system utilizes a signal generator connected to a phone line inside of the building and a signal detector connected to the outdoor phone line outside of the building in a discreet and hard to reach location. When the signal no longer appears on the line, a telephonic calling unit, which is located with the signal detector, places a distress call.
