Honeywell 950W - Wide Gap Commercial Contact Reviews
Submitted on 08/21/2019 Alarm Grid
We strongly recommend the Honeywell 950W as a wide gap hardwired door and window contact sensor. The sensor is great for use in commercial and industrial locations where a wider-than-average magnet spacing gap is needed. The sensor is easy to install and program, but you will need to run a wire from the sensor back to the panel. This is an extremely versatile sensor, and it serves its purpose well. That is why we give it a 5-Star rating.
Door and window contacts are some of the easiest sensors to understand. These devices consist of a sensor and a magnet. The sensor is mounted on the door or window frame, while the magnet is mounted on the moving portion of the door or window. For proper operation, the sensor and magnet should be as close as possible when the door or window is closed. In fact, many users will have the sensor and magnet in direct contact. This is how these sensors earned the nickname of "contacts".
With most door and window sensors, the magnet spacing gap is about one-half inch. But there are many doors and windows where achieving this small of a magnet spacing gap is simply not feasible. That is why they make wide-gap contact sensors. The 950W is one of these sensors, and it will still report that the door or window is closed when the sensor and magnet are slightly further away. With the Honeywell 950W, you can have a maximum magnet spacing gap of 2.25 inches and still expect the sensor to work reliably. Our technicians have tested this sensor and found that it works as advertised.
Please note that there are other industrial contacts that offer an even larger spacing gap. Also note that the Honeywell 950W is a Form A sensor, so you need to use a Normally Closed (NC) Series wiring configuration. But there are many users who will find that the 950W meets their needs perfectly. It is great for use in warehouses and other industrial locations where a large magnet spacing gap is needed. For that reason, we feel that it is worthy of 5-Stars.
