DETAILS
The highly effective Exit Stopper® can serve as an inexpensive door alarm and help stop theft by alerting you to any unauthorized exits or entries through emergency exit doors. The emergency exit door alarm can also serve as an inexpensive security device and help prevent theft as well. If the protected door is opened, the electronic Exit Stopper® emits a powerful 95/105 dB warning siren. A key operated override will silence the alarm and allow authorized exits.
