Von Duprin 22 ALK KIT x 3215 SP28 Alarm Kit with Keyed Mortise Cylinder for 22 Series Exit Device, C Keyway, Sprayed Aluminum Finish

The Von Duprin 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 kit 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 (furnished). 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 ALK is furnished with RX switch kit. The RX (Request to Exit) feature is used to signal the use of an opening. This device is equipped with one internal SPDT switch which monitors the push pad. The device can be connected to a security console, or may be used as a single door alarm when used with a horn and power supply. The ALK includes a 6" x 20" decal for application on door "EMERGENCY EXIT ONLY. ALARM WILL SOUND." It allows fast and accurate onsite monitoring and diagnostics. Ideal for use on perimeter doors in restaurants, libraries, retail stores and many other commercial business applications.
