Wireless Exit Stopper by STI
The Wireless Exit Stopper sounds an alert if a fire or emergency door is opened.
It emits an ear-piercing alarm (95 or 105 dB) for 30 seconds, 3 minutes, or continuously when activated. A radio signal alerts a receiver up to 1,000 feet away that it has been triggered.
The alarm is also available in annunciator mode, which announces door entry with a set of 10 beeps and then resets. A key operated override will silence the alarm for authorized exits.
