Von Duprin 22ALK 4FT SP28 Alarm Kit

Von Duprin 22ALK 4FT SP28 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. Standard Hex Key dogging not available when using an ALK. 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. Alarm kits are furnished standard with a RX-request to exit switch. Optional LX-Latch bolt monitoring, or RX2-double request to exit monitor switch are available. LX latch bolt monitoring is recommended for use with surface vertical rod exit devices.

The ALK includes “EMERGENCY EXIT ONLY, ALARM WILL SOUND” decal for application on the door. The ALK is available with two 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. Auto Reset is available in three factory set times, 1¹|2, 3 or 6 minutes. The ALK can also be hard wired and powered using a PS9 power supply. See PS9 on this page for additional information.
