Item Description

If you are a person who usually forgets to close the garage door, the Chamberlain Universal Garage Door Monitor is a great fit for you. The Chamberlain garage door sensor notifies you if your garage door is open or closed no matter which corner of the house you are in. The best thing about this wireless door alarm system is that it works with every garage door and can monitor up to four doors. The mechanism of the device is quite simple. When you leave your garage door open, the sensor automatically sends a signal to the monitor, and a garage door alarm flashes a red light indicating that the door is open. You can plug this device in any convenient location in your house and installation is minimal.

Chamberlain Universal Garage Door Monitor:
  • Works with any garage door
  • Monitors up to 4 garage doors (with additional sensors - CLDM2)
  • When light flashes red, door is open
  • Fast, easy installation; no tools needed

    Rated 4.5 out of 5★ by 43reviewers.
    Rated 4 out of 5★ by Works well Good product works well. However, I purchased two of these Chamberlain Universal Garage Door Monitors thinking I could use one monitor downstairs for both doors and have the other one upstairs, since you can purchease additional Sensor mount. It seems the senor only works with one monitor. 09/04/2011
    Rated 5 out of 5★ by Works great! I hate the feeling of waking up in the morning and realizing I forgot to close the garage door. This device is great! Put the small wireless side on the garage door. It runs on a watch sized battery. When the garage is open the base unit indicator flashes red and is located at the other end of my home. It's plugged into the wall about 60 feet away. When the garage is closed it shows a steady green light. I wish I had purchased this YEARS ago! Great product for a great price! 09/14/2012
    Rated 5 out of 5★ by works Works great except it could use better double sided tape. 09/15/2013
    Rated 5 out of 5★ by Great product. This is my second unit. Adds an extra an extra sense of security. Very easy to install 02/08/2010
    Rated 4 out of 5★ by This product works well My garage door is an insulated, metal front and back door. I have a metal fire door leading into the garage. These metal surfaces may diminish the signal so the range isn't as great as I had hoped that it would be. I can get about about 50 feet of reliable distance between the sensor and the monitor. I was going to get an additional sensor for my second garage door but don't feel it could reach the location where the existing monitor is currently located. 01/07/2011
    Rated 4 out of 5★ by Range 25 feet with antenna folded under unit - 50 or 60 feet with antenna straighted out.(this is tested through one outside wall).If you install the sensor at about 40 degree angle on door it tells youwent the door is open about 9 inches or more.( I did this on my door so I know it's open a little for venting in the summer).If installed straight up and down as per the manual, it will tells you went the door, is about half way open or more.other notes:1* if you quickly unplug and plug it in,you sometimeshave to have it relearn the sensor, as per the manual info.2* inside unit draws about a 1 to 1.2 watts.3* you could wire in a reed switch with a magnet on the door.( if you want to know if door is open 1 inch or more, I may do this next summer) 12/11/2012
    Rated 5 out of 5★ by garage door monitor This product is great. My family chooses to come in through the garage door instead of the front door. Sometimes the door gets left open. I posted this monitor by my bed. Just before going to bed if I see the green light all is good. No more leaving the garage door open all night. ! 03/28/2010
