Single Door Alarm

DA 100 series alarms overcome the inherent weakness in door mounted alarms or alarms integrated within the panic device or emergency exit lock. SDA alarms are installed above the door frame, not on the door, for maximum vandal-resistance. Employees cannot remove a 9volt battery to defeat the alarm. Emergency exits and other doors cannot be opened without sounding an alarm, unless shunted by use of the key switch.
