ABSTRACT:
An alarm and bolt apparatus for a building opening closure panel hingedly mounted within a perimeter frame in a building opening includes a bolt assembly having a bolt and a mechanism for extending and retracting the bolt, a bolt receiving housing fitted into the closure panel frame, the housing having a forward wall portion with a bolt receiving opening, a side wall portion and a rearward wall portion, an alarm circuit within the building, and a lever switch with a switch lever for operating the switch and electrical switch terminals connecting the switch within the alarm circuit, the switch lever extending within the bolt receiving housing, where the housing is sized in depth relative to the throw of the bolt so that when the bolt is fully extended from the bolt assembly, the bolt extends into the housing to an extent that the bolt is positioned laterally adjacent to the switch lever, so that when the closure panel is moved toward an open position, such movement drives the bolt laterally against the switch lever and thereupon pivots the switch lever to operate the switch and thereby complete the alarm circuit to cause an alarm to sound.
