Von Duprin 22 ALK Alarm Kit for use with 22 Series exit devices.

Specify 3’ or 4’

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 1-1/4" (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.

Also can be powered using the PS9 Power Supply. See PS9 for additional information.

Alarm kits are available with a choice of two switch kits, RX or LX. RX monitors the touchpad and is furnished standard. LX optional latch bolt monitoring is recommended for use with surface vertical rod exit devices. Specify ALK-LX. 

The ALK is available in two styles, 33A/99ALK, grooved cover and 35A/98ALK, smooth cover. 

The ALK includes “EMERGENCY EXIT ONLY. ALARM WILL SOUND” decal for application on door, or the SS push bar trim can be used instead of the door decal,specify SS push bar trim. 

The ALK is available with 2 optional circuit boards. External Inhibit (EI) allows for the use of external switch to be used to arm, disarm and reset the alarm. Auto Reset (AR) rearms the alarm after a preset time. AR is available in three factory set times – 1-1/2, 3 or 6 minutes.

When the ALK is used, standard dogging is removed. If cylinder dogging is required there are two choices. Special center case dogging is available or for 3’ or 4’ doors the ALK can be moved to the hinge side of the device and standard cylinder dogging can be added.
