Von Duprin 98/99 Series Exit Device Alarm Kit - 99ALK 4FT US28

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 horn is rated at 85 decibel.

The key switch uses a standard 1¹|4” (32mm) mortise cylinder with a straight cam (Schlage Cam reference B502-191). 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.

The ALK includes “EMERGENCY EXIT ONLY. ALARM WILL SOUND” decal for application on door.

Hardwire Installation: The new ALK assembly includes both a 24VDC input and External Inhibit feature. For continuous operation, the ALK is compatible using the popular PS-861 or other 24VDC power supplies. The External Inhibit provides remote arming and dis-arming.
