Von Duprin 4ft. Alarm Kit with Internal Horn for 99 Series Exit Device

4′ Alarm Kit with Internal Horn for 99 Series Exit Device

The ALK battery alarm kit is a simple yet effective way to deter unauthorized use of an opening. While the exit device is still a means of egress, the ALK kit contains an internal horn. When the touch bar is depressed, the horn sounds to provide an audible means of signaling that the opening has been violated. The alarm kit can be armed or disarmed by key thus allowing the exit device to be set in an armed or disarmed mode. The key switch uses a standard 1-1/4″ (32mm) mortise cylinder with a straight cam. The unit operates on one standard 9-volt alkaline battery. When the battery is weak, the horn will emit an intermittent low battery alert signal.

Over the years, Von Duprin has been an innovator in many new concepts to the industry. Currently, Von Duprin manufactures the widest range of exit devices and outside trim operations, all designed to meet the needs of architects and building owners.
