The Honeywell MPS70WG is a recessed door contact specifically designed for installation in a steel door. The MPS70WG has a 3/4” diameter and is very similar to the Honeywell 947-75. Both steel door recessed contacts use wire leads to connect to the zone wiring from your alarm control panel. The MPS70WG also comes in white and brown just like the 947-75. If you order the white steel door recessed contact, you will get a MPS70WWG and if you order the brown version, you will get a MPS70BWG.

While recessed door contacts are desirable for their discreet look, steel doors have always posed a problem. The corresponding magnet that goes along with the recessed door contact must be installed into the steel door and therefore, the steel surrounding the magnet prevents the magnet from properly energizing the internal reed switch within the recessed contact. As the reed switch is never energized, the zone used to protect the steel door remains in fault and you cannot arm your security system. However, the MPS70WG recessed contact uses a special higher powered magnet that is not obstructed by the steel door. You can use the Honeywell MPS70WG to protect any door, but you maximize the value by using it in a steel door.

The MPS70WG recessed door contact uses a Form A, SPST, normally closed internal reed switch with a contact rating of 300mA at 30VDC. There are 12” leads coming out of the backside of the recessed contact and both the magnet and the contact have plastic casing which allows you to simply press them into your recessed holes for a snug installation. If you are installing the Honeywell MPS70WG in a steel door, you must not exceed a 5/8” gap between the contact and the magnet. If you use the MPS70WG in a non-steel door, you can use a maximum magnet gap of 1.25”. Both the contact and the magnet have a diameter of 3/4” so make sure to drill a proper sized hole.

You can choose which color suits your decor best when ordering the Honeywell MPS70WG recessed steel door contact. If you desire white contacts, you will get MPS70WWG contacts and if you would like brown contacts, you will get MPS70BWG contacts.

The Honeywell MPS70WG is a hardwired recessed door contact built for use in steel doors. However, you can still use it nicely in a wooden door frame if the situation calls for it. The fact that it is built for steel doors just refers to the fact that the magnet is a little bit stronger than average. In the case of the MPS70WG, the sensor has a 3/4" diameter, so you will need to drill the holes accordingly. The sensor is fairly unique in that it uses leads instead of screw terminals for connecting wires. Overall, the Honeywell MPS70WG is a very good sensor. We give it a 5 Star rating.

There are many things to like about the Honeywell MPS70WG. For one, it comes in two (2) different color options, these being white and brown. Although the color doesn't really matter for a recessed door contact, as you will never really see it unless you look at the side of the door frame with the door opened, it's still nice that a color option is available. The sensor and magnet allow for a decently large magnet spacing gap. This spacing gap is 5/8" in a steel door, or 1 1/4" in a non-steel door. The magnet is very strong and will ensure reliable and effective performance when installed properly.

There are not many downsides associated with the Honeywell MPS70WG. Like any recessed contact, holes will need to be drilled in the door and its frame. And since this is a wired sensor, a wire will need to be run from the panel to the sensor. This can be difficult for a DIY user, especially if they are not used to running wires. There is also the fact that this sensor is discontinued, and you cannot purchase it new. But if you find a used model, it should still work fine. All things considered, these downsides are relatively minor, and they do not stop us from giving the Honeywell MPS70WG a 5 Star rating.

Good: Two Color Options, Large Magnet Spacing Gap, Strong Magnet, Reliable

Bad: Holes Must be drilled, Running wires, Discontinued

Bottom Line: 5 Stars
