Featuring a loud 105dB alarm, UV-stabilized polycarbonate housing, and versatile mounting options, it installs quickly on virtually any door.

## Description

The Exit Stopper is a unique and highly effective way to alert you to any unauthorised exits or entries through emergency exit doors. It can also serve as an inexpensive security device and help prevent theft. It is available in red or green and can be mounted or installed on almost any type of door, including remote placement of the sounder. The highly visible ‘STOP’ sign discourages unauthorised use of emergency doors. 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 facility will silence the alarm and allow authorised exits. When the door is closed, a number of reset options are available including an automatic function. A variety of alarm durations and setup features are available (see User Programmable Features chart overleaf). The Exit Stopper is fitted with a 9V PP3 alkaline battery.
