How Do I Replace A Door Sensor’s Magnet?
To replace a wireless door or window sensor, users can use the Honeywell 5899 magnet.
The 5899 magnet was designed for the Honeywell 5816 wireless door, window sensor, but is compatible as a replacement magnet for other wireless door and window sensors as well. The 5899 magnet’s dimensions are 1.5” long, 1/2” wide and 1/2” deep which is slightly larger than a typical magnet and can be used without the case if needed. Install the magnet no further than 1/2” from the contact when the door or window is closed, making sure to align the magnet along the long side of the wireless contact that has the magnet alignment marks etched in the plastic case. In addition to the magnet alignment marks on the side of the 5816 contact, the mounting plate for the 5816 also has a plastic strip that can act as a guide for installing the magnet. The 5816 transmitter has an internal reed switch that is positioned on the side with the alignment marks. If the magnet is installed on the wrong side, the wireless transmitter will not function properly and the zone programmed for that particular transmitter will remain faulted until the magnet is properly aligned. A plastic spacer is included with the Honeywell 5899 magnet, which can be used to properly align the magnet with the corresponding sensor when the door or window frame is not flush with the door or window.
To replace a hardwired contact, users can use the Honeywell 945-M which is a surface mount magnet that is compatible with many surface mount door, window contacts. Install the Honeywell 945-M magnet within 1.125” of the installed contact. If using the Honeywell 945-M magnet with any other hardwired surface mount door, window contact, please check the magnet spacing gap before mounting the magnet to ensure proper spacing.
