| The 22ALK exit alarm kit is a simple yet effective way to monitor the use of an exit device and deter unauthorised use of an opening. While still a means of egress, the unit contains an internal horn. When the touch bar is depressed, the horn sounds to provide an audible means of signalling that the opening has been activated. The key switch allows you to arm and disarm the alarm. The unit operates on one standard 9-volt battery. When the battery is weak, the horn will emit an intermittent signal. An “EMERGENCY EXIT ONLY. ALARM WILL SOUND” decal for application on the door is supplied as standard and requires use a 32mm mortice cylinder which is ordered separately |
