How It Works N/A If the protected door is opened, the electronic Exit Stopper® emits an ear piercing alarm for 30 seconds, 3 minutes or continuously (as preset by the user). A key operated override will silence the alarm and allow authorized exits. The unit can be set for a 15 second delay before arming or tripping. Exit Stopper® “Always Active” allows the key holder to reset the alarm, but does not allow the alarm to be turned off. Exit Stopper® is fitted with a 9 VDC alkaline battery. It is available in red or green for almost any type of door, mounting or installation, including remote placement of the alarm (not for outdoor use).
