Von Duprin ALK Alarm Kit

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. The horn is rated at 85 decibel. The assembly includes both a 24VDC input and external inhibit. The external inhibit provides remote arming and disarming.

Features:

• The key switch uses a standard 1-1/4" (32mm) mortise cylinder with a straight cam (Schlage 20-001, B502-191 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.
• The alarm can be re-armed with a 1-1/2, 3 or 4-1/2 second time delay.
• 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, 99ALK, grooved cover and 98ALK, smooth cover.
• The ALK includes a 6" x 20" decal for application on door "emergency exit only."
• 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
• Standard cylinder dogging
• Note: For latch bolt monitoring on a 98/9975 with ALK, specify a SS7500 lock. LX switch not available for 98/9975 devices.
