Product Overview

The highly effective Exit Stopper can serve as an inexpensive security device and help stop theft by alerting you to any unauthorized exits or entries through emergency exit doors. If the protected door is opened when in exit alarm mode the electronic Exit Stopper emits an ear piercing, 105 or 95 dB, alarm for 30 seconds, 3 minutes or continuously (as preset by the user). When in annunciator mode it announces door entry with a set of 10 beeps. 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.
