The CLDM1 open door monitor simply attaches to your tilt or panel door and the monitor can be left in a place where you can see it, be it in the kitchen, study or wherever it would be handy to know if you have closed the garage door or not.
The red light indicates that the door is open and the green light tells you that it is closed. No more running out to the garage to check! Just one glance and you'll know.
for use with all sectional and tilt garage doors
