Abstract

A device includes a housing, a tamper switch supported at the housing, and an actuation arm supported at the housing. The actuation arm includes an actuation column. The actuation arm is movable between a tamper switch engaged position and a tamper switch released position. In the tamper switch engaged position, the actuation column contacts the tamper switch and the actuation arm is at a first angle relative to the tamper switch. In the tamper switch released position, the actuation column is spaced apart from the tamper switch and the actuation arm is at a second angle relative to the tamper switch. The second angle is different than the first angle.
