Tools and Hardware Reviews of Chamberlain CLDM1 Clicker Garage Door Monitor
Customer Review: Installation considerations
Summary: 5 Stars
I'm really pleased with this purchase. I live on a very busy street and over a couple of decades I've lost an expensive bicycle, a drill set, and a heat gun due to accidentally leaving the garage door open.
I just installed the Chamberlain Monitor so I can't comment on longevity, but I was concerned about the many reviewers who have reported bad installation experiences.
After installing mine, I suspect that one of the most common causes of problems is poor placement.
Attach the sensor to the garage door at the highest possible point where the sensor is still in a vertical position. That way, the garage door will have to be completely (or very nearly completely) closed before the sensor will be vertical. (Otherwise, the garage door could be partially open and the sensor would still be horizontal and register "closed.") Also, in this position the sensor will be as high as possible for ideal reception by the receiver.
Place the sensor on the garage door as close as possible to whatever direction the receiver is going to be in. That is, minimize the distance between the sensor and the receiver as much as possible.
But also be careful to position the sensor so that there are no metal or other super hard materials in the line of sight between the sensor and the receiver. Be particularly careful to consider the metal rails and rollers at the edge of the garage door - metal will obstruct the signal.
The sensor operates on a round lithium 2032 battery but the receiver must be plugged into an AC outlet - it comes with a transformer and a 5' cord.
Place the receiver in your house as high as possible and in a position that is likely to have the most unobstructed line of sight between the sensor and the receiver. A 9" relatively stiff wire antenna is attached to the receiver. It comes coiled - stretch it out carefully, removing any kinks so it will be as long and as straight as possible. Position the antenna so it extends straight up from the receiver.
My receiver is positioned on a wall in the kitchen about 7' high and about 35' from the sensor. There is a workout room and a clothes washer/drier between the garage and the kitchen so I was careful to position both the sensor and the receiver so the signal wouldn't be obstructed by heavy stuff. One of my walls used to be the stone exterior of the house so I couldn't get around that - but the signal seems to be making it through just fine anyway.
I first taped both the sensor and the receiver in position so I could test the setup a few times before permanently installing them.
One final note: A small piece of Velcro comes with the sensor for attaching it to the garage door. I'm not convinced that this is going to be a permanent solution since we often have 100+ degree days in our town and the Velcro adhesive may not last long. If it doesn't, I may just reattach it with a dot of super glue to the adhesive side of both pieces of velco - we'll see.
That's it - hope this helps.
Description of Chamberlain CLDM1 Clicker Garage Door Monitor
Sometimes you just forget to close the garage door. But if "sometimes" is closer to "usually" for you, you may run the risk of having your garage emptied out by opportunistic passers-by, and you will certainly pay more to heat your house. Chamberlain's Clicker Garage Door Monitor helps you minimize the likelihood that you'll leave the biggest door in your house open. The device mounts easily without tools to your garage door via a Velcro strip; if your door is open, the sensor sends a signal to the monitor, causing a red light to flash. The monitor may be plugged in anywhere in your house where you're likely to notice the flashing light. Depending on your garage-door habits, this device could help prevent theft and lower your heating bills. Includes lithium battery.--Josh DettweilerWhat's in the Box
