Abstract
A closure latch or bolt monitoring device having a housing mountable in a closure frame which housing receives a latch or bolt. A pivotal rocker plate is normally biased to a rest position in which a flange portion of the rocker engages a switch connectable to an alarm system. When a latch or bolt is extended into the housing, the rocker plate is pivoted causing it to disengage from the switch providing an indication to the alarm system that the bolt or latch is properly engaged in the closure. An alternate embodiment allows separate monitoring of two lock components such as a separate bolt and latch.
