Exit Stopper® Multi Function Door Alarm with Remote Horn

If the protected door is opened, the electronic Exit Stopper emits an ear piercing alarm from the main unit and remote horn for 30 seconds, three minutes or continuously (as preset by the user). A key operated override will silence the alarms and allow authorized exits. Another option is annunciator mode, in this mode it announces a doors opening with a set of 10 beeps and then resets. Exit Stopper is fitted with a long life 9-VDC alkaline battery. It is available in red or green for almost any type of door, mounting or installation.
