Von Duprin 22ALK.RX.SP28 Alarm Kit | Relcross Door Controls

Exit Alarm - Retrofit Kit

Use with 22 Series Exit Hardware Only.

The ALK Alarm Kit is a simple yet effective way to deter unauthorised use of an opening. When the touch bar is depressed, a horn signals that the opening has been violated. The alarm kit can be armed or disarmed by a key, allowing the exit device to be set in an armed or disarmed mode. The horn is rated at 85 decibels.

The assembly includes both a 24VDC Input and External Inhibit as standard. The External Inhibit provides remote arming and disarming
The key switch uses a Schlage 20-001.114.C.626 | Mortice Cylinder (20-001) w. L583-477 Straight Cam, which is included with the kit.
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 (but not supplied) with this kit. This kit allows the device to resume the alarm option after a pre-set time. Pre-set times can be field-selected at 1.5, 3, or 4.5 minutes
Alarm kits are available with 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 or when an alarm needs to sound from both the exit device and trim side of the door. Specify ALK-LX

The ALK includes a decal for application on the door 'EMERGENCY EXIT ONLY. ALARM WILL SOUND'

Designed specifically for use in areas where frequent abusive treatment can be expected, the 22 series is constructed from a heavy gauge rolled steel section and has the proven heavy-duty touch bar mechanism that has been used so successfully in all architectural-grade Von Duprin touch bar devices. It is best suited to heavy-duty situations on perimeter and internal doors where safe egress in panic emergencies is required.
