Works the same as G.R.I. products
Works exactly as intended for pool alarms or door alarms.Magnet activated switch operates at the same clearance as the name brand reed switches.I’ve already purchased two more sets to replace worn out door contacts.MAKE SURE you know if you need “normally open” or “normally closed” switch PRIOR to install!

It worked great, and helped me out of a jam with my alarm company!
One of my alarm zones failed and when the alarm company came out to fix it they told me I had to abandon my wired connection and replace it with a wireless sensor. They said the wired sensors weren't available any more. Well, they are, and these were a great solution to my problem. They are easy to work with and they work just fine. Thanks to the vendor for proving my alarm company wrong!

Works great - very pleased
Replaced a faulty door alarm switch. A perfect replacement for the one installed by SST in Sun City Festival.

Worth the money!
Worked great, just like the original ADT sensor but much cheaper.
