Abstract
An intrusion detector comprises a housing including a cover and baseplate mounting a circuit board. The cover and baseplate are removably mountable to a base. A motion sensor and bracket are mounted to the circuit board. The cover has a lower lookdown window. A lookdown enable/disable actuator extends from a rear side of the circuit board and is accessible through the baseplate. The actuator is operable to move a door pivotally mounted to the bracket between an on position to enable a lookdown function and an off position to disable the lookdown function. The detector is normally mounted on a wall by securing the base to the wall. The cover and baseplate can be removed from the base. A screwdriver can be used to turn the actuator. The cover and baseplate can then be remounted to the base.
Claims14
An intrusion detector comprising:
- a housing enclosing a circuit board having front and rear sides and a cover mounting the circuit board to cover the front side and to define an interior space, the cover having a lower lookdown window;
- a bracket mounted to the front side of the circuit board, the bracket having opposite side walls with one of the sidewalls having a pair of pivot tabs at a lower end defining an axis perpendicular with the circuit board and aligned with an opening in the circuit board;
- a motion sensor mounted to the circuit board between the bracket opposite side walls and aligned to detect motion visible through the lower lookdown window;
- a door hingedly mounted to the pivot tabs;
- and
- an actuator located at the rear side of the circuit board and operatively connected to the door through the opening, the actuator being operable to move the door between an on position to enable a lookdown function and an off position to disable the lookdown function.
