Essential Info

This additional sensor for the Chamberlain Garage Door Monitor is used for homes with multiple garage doors. It mounts on the garage door and signals the receiver inside the house. The unit is battery powered (included) and requires the Garage Door Monitor receiver to operate.


More Info

The Universal Garage Door Monitor works with any overhead garage door. Mount the sensor to the back of your garage door with the included Velcro strip. When the door opens, the sensor moves into the horizontal position and sends a signal to the monitor that the door is open. The monitor then provides simple, visual cues to indicate your garage door's status: When the light flashes red, the door is open; when the green light is on, the door is closed.

This is a simple but usful device. I always got upstairs and wondered if the garage doors were shut, now have this next to my bed and no more trips downstairs.

Works great and is a great value purchased through your company
Fred R. -- Colorado   12/12/2011
This device works great, until it doesn't and IMHO it should work a lot longer than it does. My third one, and last one, just stopped working. In none of these cases did the reset button work. Great product while it lasted, but not a quality product. Needs some work on longevity.

does not work. sometimes says door is open when it is not
CARLOS -- rockledge, FL   4/28/2011
This system works like a charm. Had to get an extra sensor because I forgot to get the old one when I got the garage door replaced. Easy to program to the receiver. It just works.
