Alarm kit (ALK) 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 decibels.

The “EI” External Inhibit feature is standard on the ALK at no additional charge

The ALK includes a 6"x 20" decal for application on door “EMERGENCY EXIT ONLY. ALARM WILL SOUND.”
