Coldroom Door Left Open Alarm
DA1 Standard Door Open Alarm with Magnetic Switch
The alarm is triggered by the door being left open for longer than the time delay is set for. Once activated, the red flashing light is combined with a 80db pulsing sounder to warn that the door has been left open. Once the door is closed the alarm will automatically reset
Leaving a cold store door for a longer period than necessary causes several problems. Not only does it increase operating costs (often by a significant amount) as the refrigeration plant has to work harder, it can also result in ice forming around the threshold and on the entrance floor (leading to poor door closure, sealing issues and a potential slip hazard).
