Review on 🚫 Honeywell Transmitter: Limited Stock Alert - Discontinued Model by Honeywell by Jimmy Jefferson

I have a wired system and when it was installed almost 50 years ago I had built in magnetic sensors wired in series. Everything worked well, but eventually had to fail. I left them in place (hidden) and installed new Honeywell 5800 mini sensors on each window. one doesn't work. They are small and unobtrusive and almost invisible with curtains etc. The best way to go.
