When Would I Need a Honeywell Steel Door Contact?
If you have a door or window made from steel rather than your traditional wood, a lot of door and window contacts will not work properly. Oftentimes, they won't work at all. The solution is an extremely strong magnet such as the one included included in Honeywell's 947-75T sensor and magnet. The steel of the door makes less powerful magnets ineffective so that the system can't tell if the door is open or closed.
If you have a door like this, and can't figure out why your contacts aren't working, you may not need to replace the sensor altogether. A lot of times, all you will have to do is change out the magnet you are using and replace it with one of the magnets in the 947-75T, 947-75, MPS70WG, the 947 package.
Beware, however, if you have installed the 5800MICRA wireless door and window contact. For whatever reason, we have found that this sensor is finicky, and doesn't do well with the steel door magnets. If you would like a wireless contact that will work with these stronger magnets, we have found that the 5818MNL is a much better choice when trying to pair a wireless sensor to a strong, steel door magnet.
