Alarm emitter with signalling activating trigger - has alarm wire(s) activating signalling on tear or short circuit

摘要

The alarm emitter has at least one wire (5), activating the signalling device on tearing or short circuiting. The wire is provided in a closing or hinge region of a container or room to be protected on a wall, or on parts to be mechanically secured. At least one screw (10) or a bolt, serving anchoring of the closing or hinge region and/or the container wall, is supported at a rated breaking point (4) fitted with the alarm wire. Between the rated breaking point and the two parts, coupled by the screw or bolt, a gap (3) can create free play upon breaking of the rated point of the screw. USE/ADVANTAGE - Burglar alarms, with reliable and fail-safe protection.
