Connected wires, added protective cap nice touch then installed in minutes. The sensor comes in two parts that only have to be near each other to register lots of margin, can even be more than an inch apart! Now I get proper messages about status of garage door, with easier sensor install than Nexx sensor.

Couldn't be happier. I've got mine hooked up to an Good sensors. I'm quite sure most people aren't buying these for this reason, but it's a perfectly good application. If you ever need to close a circuit when two things come close together in proximity but not necessarily touch , then this will do the job. These were used as replacements when I had new windows installed. The original modules had yellowed, and were sufficiently old that I chose replacement.

Mounting was straightforward. Screws and covers are all included. I installed one alarm circuit at a time -- typically contacts.

For those, I taped a magnet to each contact, and queried the alarm system for all closed. This tested my wiring -- any opens would have been noted at this point. Then I installed each magnet for this circuit, and tested again. Finally, I opened each window to confirm the lack of short circuits which would have prevented an alarm from occurring when the window opened.

Following this methodology made the installation straightforward. These have been operating properly for several weeks with no issues. Prior experience indicates that failures are rare for properly installed new devices. I have had year old switches develop intermittent opens, resulting in false alarms different house , so periodic replacement -- every few decades -- is a good idea, if your technology still requires a wired window contact.

We replaced our back door and the alarm sensor never seemed to work properly again. Based on the low price, we decided to try this product. It is just what we needed! I gave up on installing this contact. My existing contact disappeared when workers replaced my door and frame. I had four wires red, black and twisted green and yellow coming out of the wall, but this contact only had places to attach two.

Then when I tried to experiment, I couldn't even get the screws to budge. So it was a fail. Go to Amazon. Back to top. Get to Know Us. Shopbop Designer Fashion Brands.
