    Video Transcript

    After undergoing some exciting changes STI are pleased to introduce the newly improved Exit Stopper.

    On and off text has been removed and replaced with their corresponding symbols. Users now have the choice of installing one of 20 additional language labels. The powerful audible warning alarm is now complemented by a visual flashing beacon. Both audible and visual warnings will alarm when the device is armed and activating as well as when the battery is running low. Universal sound symbols have been added to either side of the sounder for recognition globally. The text along the top of the Exit Stopper has also been updated.

    The new STI Exit Stopper, available now.

    How It Works

    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.
