Seco-Larm SM-226LQ Overhead Door Mount N.C. Magnetic Contact w/Pre-Wired Leads

I have not installed this one.The last one works well.It can get stuck below Zero degrees. If this happens wave a stronger magnet over it. This wakes it up.

Awesome no need to have it fraction of an inch away from each other, works very well

Worked just like it should. No problems.

Installed on my garage door easily. Functions flawlessly. Using this with my Insteon ISY994i via an EZIO8SA analog input port.

I owned the model ODC-59A shown in the picture and wanted the same one to match for my garage doors. However, a different model was shipped. While it works fine, it is deceptive business. Would have cost me to ship it back.

Great product

I purchased this for use in my garage to serve both as an alarm contact and as an LED indicator switch. Beware of the inaccurate description (at the time of this review). This product has only two wires, even though the current description says it has three. I have another two wire Seco-Larm switch like this and it's worked flawlessly. That's why I ordered this item. Unfortunately, the description was incorrect. For the three wire version (NO/NC), order the Seco-Larm SM-226L-3Q also on Amazon. I am returning this item.

I had to make a second purchase of the same item because the first, from china, the one on mars. had failed me, so i believed. thesecond one arrives in 7 days, from good ol USA.
