Patent Application 20070290845 December 20, 2007
Abstract:
A tamper
detection mechanism in a sensor device comprising a body and a mounting
base. The sensor device includes a substantially central resilient
element/plunger attached to the mounting base. The body houses a printed
circuit board includes a surface for mating to the resilient element to
create a circuit. The mounting base may be removably affixed to a
structure such as a wall or ceiling. When the mounting base is screwed
into the structure and the body is coupled to the mounting base, the
plunger is compressed and exerts a continuous pressure on the printed
circuit board surface to complete the tamper circuit. If the sensor
device is uncoupled and/or removed from the structure, the circuit is
opened and a tamper indication signal is produced.
