ABSTRACT:
A security arrangement includes a mounting device having an upstanding wall. The mounting device is mounted to a surface of a structure such that the wall is oriented substantially perpendicular to the surface. A security sensor senses an event that occurs outside of the security arrangement. A tamper detector is attached to the security sensor and includes an optical emitter, an optical receiver, and a slot disposed between the emitter and the receiver. The emitter transmits optical energy that is received by the receiver through the slot. The wall of the mounting device is received in the slot when the tamper detector is coupled to the mounting device to thereby block the transmission of the optical energy from the emitter to the receiver. A controller is communicatively coupled to the receiver and produces a tamper signal in response to the receiver receiving the optical energy.
