The Von Duprin ALK battery alarm kit is a straightforward yet effective way to deter unauthorized use of an opening. Even as the exit device is still a means of egress, the ALK kit comprises 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 may also 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 an ordinary 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 usage of an opening. This device is equipped with one internal SPDT switch which monitors the push pad. The device may also be connected to a security console, or can 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 to be used on perimeter doors in restaurants, libraries, retail stores and plenty of other commercial business applications.
