A housing for an alarm includes a base adapted for mounting on a wall, a cover detachably connectable to the base and a sabotage detector for triggering an alarm signal in the event of unauthorized removal of the cover or forcible removal of the alarm from the wall. The base includes a breakaway portion which can be formed as strip-shaped region bordered by weak points. A number of screw insertion points extend through the breakaway portion for fastening the breakaway portion to a wall with one or more screws. A web projects from the breakaway portion and towards the cover such that when the housing is closed, the web engages a contact switch mounted in the cover. In the event of the housing being ripped off the wall, the strip-shaped region is broken off the base and remains on the wall, thereby opening the contact switch. The web is also disengaged from the contact switch in the event of unauthorized removal of the cover from the base.
In a housing for an alarm, having a base intended for fastening to a wall and a cover detachably connectable to the base, the improvement comprising:
A wall mountable housing for an alarm component comprising:
The housing according to 16, wherein the cover assembly is fixed to the base by a screw, and wherein the cover further comprises a flap for covering said screw.
