Abstract
An alarm is operatively associated with a movable frame and a stationary frame of a sliding door assembly. It has a plunger engagable with one frame or the other, which plunger is urged outwardly and activates a signal if the alarm is removed from its position. The alarm includes a case in which a modular component can be inserted with the component including a source of power, contacts, and a signal which can be an audible signal or a sending signal which activates a remote burglar alarm. The case of the alarm has a locking pin which can lock the plunger in place when the alarm is removed by the occupant. The alarm is also designed with a gravity-operated block which prevents the plunger from being pushed back into the case to turn off the alarm unless the alarm is turned upside down.
