Honeywell 944SP

The Honeywell 944SP is a recessed contact that you can connect to a wired alarm control panel to protect any door or window. Unlike the Honeywell 944T recessed contact which uses terminal screws to connect to the contact loop wire, the 944SP has wire leads which you must splice to your contact loop wire. Each 944SP recessed contact includes wire crimps to help with your wiring connections. Contrary to the picture, the 944SP brown version was discontinued by Honeywell and only comes in white (944SP-WH).

The 944SP door and window recessed contact uses an internal reed switch with a rating of 100mA at 28VDC. The internal reed switch is a Form A, SPST, normally closed contact that can be connected to any wired zone setup for a normally closed device. If you need a normally open recessed contact, you should look at the Honeywell 944-2GY instead.

Recessed door and window contacts require a more complicated installation than surface mount contacts. However, once installed, recessed contacts are much more aesthetically pleasing as you cannot see them when the door or window is closed. To install your Honeywell 944SP contact, you will need to drill a hole in your door or window and a corresponding hole in your door or window frame. The contact hole should be 3/4” diameter and the magnet hole should be 3/8” diameter. The 944SP recessed contact has a 5’ zip cord coming out of the backside with (2) wire leads. Once you have run your wire from your alarm control panel to the door or window to be protected, simply splice the wire connections and press the 944SP contact into the hole until the cap is flush with your door or window. Next, press the magnet into the magnet hole. Now, when you close your door or window, the contact should be directly across from the magnet. Ensure that the gap between the contact and the magnet does not exceed 3/4” otherwise you will not be able to get the contact loop to close and you will have a faulted zone.
