Description

The Honeywell 7945 is a surface mount magnetic contact with leads instead of terminals. The 7945 is also a member of Honeywell’s XTP Series of commercial contacts. All XTP contacts are designed to protect against lightning strikes and power surges. As commercial contacts are often installed in outdoor buildings, power surges can be a major problem. If enough voltage runs through a contact, the internal reed switch becomes fused and the contact will never go into alarm regardless of whether the magnet is adjacent or not. Unfortunately, there is no way to supervise a fused contact. Unless you are regularly testing all of your commercial contacts, your property may not be protected if you are using a non-XTP commercial contact and it is installed outside. Use Honeywell XTP contacts so you don't have to worry about a surge fusing your contacts as they can withstand a power surge of up to 2400VDC.

The Honeywell 7945 comes in (3) colors. If you want a white contact , you should order the 7945WH. If you want brown, you should order the 7945BR. Finally, if you want a grey contact, you should order the 7945GY.

Unlike most Honeywell contacts that use terminal screws for wiring connections, the 7945 contact has a 6’ CLII cable lead with (2) wires which you would use to wire to your zone circuit. The internal reed switch for the 7945 is a Form A, SPST, normally closed contact. If you wanted a Form C, SPDT, normally closed or normally open contact, you should look at the 7945-2GY contact instead. The normally closed contact for the Honeywell 7945 is rated for 100mA at 28VDC.

The 7945 XTP surface mount magnetic contact has many of the features found in Honeywell commercial contacts. In addition to the XTP surge protection, the 7945 commercial contact has an epoxy sealed case to protect it from water or corrosion. Also, the Honeywell 7945 operates in temperatures between -40° F and 194° F. Finally, the contact has an extra wide magnet gap of 2.5” which makes it ideal for the more unique commercial applications. If your magnet gap is smaller than 1”, any door or opening you are trying to protect that may shift in the wind will cause false alarms. With the 7945 contact’s wide gap, you can be confident that all alarms triggered are real emergency events.

There are (3) different replacement magnets for the 7945 commercial contact depending on which color you choose. If you choose the white 7945WH contact, you should use the 7945WH-M magnet if you need a replacement. The 7945BR-M is a brown magnet to match the 7945BR contact and the 7945GY-M is a grey magnet to match both the 7945GY contact and the 7945-2GY contact.

Excellent Commercial Contact Sensor!
Submitted on 09/17/2019 Alarm Grid

The Honeywell 7945 is an outstanding commercial-grade contact. It is perfect for use on commercial, industrial, and overhead doors. It is an extremely tough and durable sensor, and its 2.5 inch magnet spacing gap is very impressive. We recommend this contact for anyone need an commercial-grade sensor. That is why we give it a 5 Star Rating.

A unique aspect of the Honeywell 7945 is that it uses leads for connecting a wire instead of terminals. This will work better for users in certain situations, and it definitely gives the Honeywell 7945 an important niche in the market. These leads are specified as 6' CLII cable leads. You connect the two (2) wires from the sensor to the hardwired zone terminals like you would do for pretty much any hardwired contact sensor. Please note that this is a Form A, Normally Closed (NC) sensor.

One of the best aspects of the Honeywell 7945 is its excellent durability. It is a rugged sensor that is prepared to withstand the challenges of being used in commercial applications. The sensor can withstand power surges of up to 2400VDC. This helps prevent the sensor from becoming permanently damaged due to a fused reed switch. This can sometimes happen if the sensor is used in an outdoor environment. But you will not have to worry about that with the Honeywell 7945.

The sensor also possesses an impressive magnet spacing gap rating, as it allows for up to 2.5 inches of spacing between the sensor and magnet when the door is closed. This makes the sensor perfect for use on commercial doors where a larger than average spacing gap is required. Our technicians have found that the Honeywell 7945 works very well in many applications. We give the Honeywell 7945 Contact 5 Stars for its great versatility. We recommend it for anyone needing a contact with a large spacing gap.
