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.

For hardware applications

The assembly includes both a 24VDC Input and External Inhibit standard. The External Inhibit provides
remote arming and dis-arming.

The key switch uses a standard 1 1/4" (32mm) mortise
cylinder with a straight cam (Schlage 20-001, L583- 477 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.

Auto reset (AR) option is available with this kit. This kit allows the device to resume the alarm option after a
preset time. Preset times can be field selected at 1.5, 3, or 4.5 minutes.

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