Abstract
The lock strike device is used with closable openings and is electrically connectable to an electrical monitoring circuit so that the presence or absence of a latch or deadbolt in the device can be automatically detected. The device includes a strike box having spaced sidewalls and a closed rear end. The first sidewall and adjacent portion of the rear end define an elongated cutaway portion through which an elongated blade trigger is spring biased into the strike space. The trigger is hinged at its front end to a box connected to the front of the sidewall. The rear end of the trigger is a head which urges a spring loaded lever arm of an electrical switch mounted on the exterior of the housing rear end into an open circuit position. A movable tab extends transversely into the space from the trigger. The tab senses the presence of a latch to provide a signal to an indicator.
