The Exit Stopper is a unique and highly effective way to alert you to any unauthorised exits or entries through emergency exit doors. If the protected door is opened, the electronic Exit Stopper emits a powerful 95/105 dB warning alarm and a flashing beacon also alerts you to misuse. A key operated override will silence the alarm and allow authorised exits. A choice of 21 language warning labels are available and universal sound symbols mean the Exit Stopper is suitable for any door. The Exit Stopper is available in red or green.
