The Honeywell 940 is a magnetic door contact and window contact that can be used with any wired alarm control panel. The 940 contact used to be available in (2) colors, but Honeywell discontinued the 940BR brown contacts so you can only get the 940WH white contacts.
The 940 is a surface mount magnetic contact that you can use to protect your home’s door and windows. You can even use the 940 contact to protect other openings like a liquor cabinet or an office drawer with important documents inside. When the magnet is close to the contact, the alarm control panel is in a normal, ready to arm state. When you open the door or window protected by a 940 contact while your security system is armed, an alarm will be triggered. You will not be able to arm your alarm control panel if you have open windows or doors. Your alarm keypads will display a fault when any of your 940 contacts are separated from their magnet.
The Honeywell 940 contact is very small so it is ideal for homes or offices where decor is a concern. The aesthetically pleasing cover even hides all unsightly mounting screws and terminals screws. Each 940 includes spacers and mounting screws to go along with the contact and magnet. You can use adhesive tape or the mounting screws to secure the contact and magnet to your door or window. The spacers are used for unusual door and window frames so that you can get the contact flush with the magnet when the door or window is closed. The magnet gap is 3/4” so you must ensure that the contact is within 3/4” of the magnet when the door or window is closed. The 940 contact uses a Form A, SPST, normally closed internal reed switch that has a rating of 100mA at 28VDC. If you choose to use an end-of-line resistor (EOLR) to supervise your contact loop, you can install the EOLR under the cover of the 940 contact or you can put it at the wired zone within the alarm control panel.
The 940 is super small. The exact dimensions are 1.52 inches in length by 0.53 inches in width by 0.47 inches in height.
