Sometimes referred to as a door screecher, the DorWatcher is an alarm unit used to prevent doors being left open for extended periods of time. Typically used to alarm kitchen doors in student accommodation, the alarm is activated if the kitchen door remains open for more than 1 minute prompting people in the vicinity to close the door thereby preventing smoke from cooking drifting into corridors and causing fire alarm activations. Once activated the alarm is automatically reset as soon as the door is closed.
