Von Duprin 22 ALK Exit Alarm Kit

The 22ALK battery alarm kit is a simple yet effective way to monitor the use of an exit device. While still a means of egress, the unit contains an internal horn. When the touchbar is depressed the horn sounds to provide an audible means of signaling that the opening has been violated. The key switch uses a standard 1-1/4 mortise cylinder. The unit operates on one standard 9-volt transistor battery. When the battery is weak the horn will emit an intermittent signal. The 22ALK includes EMERGENCY EXIT ONLY. ALARM WILL SOUND decal for application on door.
