Product Description: Von Duprin Exit Device Battery Alarm Kit: Aluminum 

Series: 99

For: 48" Door 

Finish: Aluminum 

The ALK is available in two styles, 99ALK, grooved cover and 98ALK, smooth cover. 

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.

The horn is rated at 85 decibel.
