We have a home alarm system, installed about 15 years ago, with an Acron control. About two weeks ago someone was working on the roof, and evidently the vibration caused the door magnetic sensor to fall out. We did not notice it, but now the door zone is always lit.
The sensor looks to be about 1/4" in diameter. The magnet is still in the door itself. It's hard-wired, not wireless, if that is not obvious. Can someone recommend me a source for online parts ordering? (I will just order two, one each normally open and normally closed, since the shipping is usually more than the items themselves.)
I can't locate the paperwork for the orginal installer, so that's out for the moment. I plan on replacing it myself, as the wire location is reasonably accessible in the attic.
Thanks in advance for any advice,
Hank Murphy
