Abstract (en)

A security alarm system (10) has a fine trip wire (12) and a continuity monitor (14) for monitoring continuity of the trip wire. If the trip wire is broken then a trigger signal is provided by the continuity monitor and activates an alarm (16) such as a rocket or flare. The continuity monitor may monitor the continuity of the trip wire continuously, or at periodic intervals.
