Loheat Door Left Open Alarm DA2

 Coldroom doors left open for over-long periods increase energy costs significantly, so controlling door openings to reduce the flow of warm air and moisture will produce large energy savings, cut product deterioration and avoid Health and Safety problems such as door threshold icing. Our new Loheat ‘Speaking’ door open alarm is a very effective and inexpensive cost saving solution to these problems. The wall mounted steel alarm box is compact and easy to install and connect to the robust magnetic door sensor. It is suitable for sliding and hinged doors. The alarm is silent until activated by an over-long opening period via a variable time delay system. When activated the high visibility red flashing beacon is combined with a strong commanding voice instruction to close the door. This voice message is repeated continuously until the door is closed, when the alarm automatically resets. A green LED light confirms the power is on and the alarm is active.
The alarm also incorporates an externally readable counter which shows how many times the alarm has been activated. This provides useful management data and is easily reset to suit relevant timescales.
