Deadbolt Electric Bolts
A compact unit designed to fit narrow stile doors. This lock comes complete with keepers which makes it simple to install on all types of doors or windows whether single, pair, double acting or overhead - either inswinging or outswinging. The the lock is aligned with the keeper to bolt projects into the keeper thus locking the door. The bolt is retracted and the door unlocked by means of a remote switch, a key switch, time programmer or other electrical contact which interrups the power. Ideally suited to programmed locking and unlocking of laundromats, lobby doors of public buildings, or other unattended areas. Use of a lighted push button switch at the door (Alarm Lock Model 191) assures that people inside the building can exit after lock-up time; the door will relock automatically after exit. May be tied in with smoke detectors or fire alarm system for automatic unlocking in a fire emergency.
