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.
Claims18
A device comprising:
- a housing;
- a tamper switch supported at the housing;
- and
- an actuation arm supported at the housing, the actuation arm including an actuation column, the actuation arm being movable between a tamper switch engaged position and a tamper switch released position, wherein:
- in the tamper switch engaged position, the actuation column contacts the tamper switch, and the actuation arm and the actuation column are at a first angle relative to the tamper switch, and
- in the tamper switch released position, the actuation column is spaced apart from the tamper switch, and the actuation arm and actuation column are at a second angle relative to the tamper switch, the second angle being different than the first angle.
A method comprising the steps of:
- mounting a housing at a mounting surface, the housing supporting a tamper switch and an actuation arm, the actuation arm including an actuation column;
- and
- when mounting the housing at the mounting surface, changing an angle of the actuation arm relative to the tamper switch to move the actuation arm from a tamper switch released position to a tamper switch engaged position, wherein 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, and wherein 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 being different than the first angle, wherein changing the angle of the actuation arm further comprises changing an angle of the actuation column relative to the tamper switch, wherein in the tamper switch engaged position the actuation arm is at the first angle relative to the tamper switch, and wherein in the tamper switch released position the actuation arm is at the second angle relative to the tamper switch.
