The Commercial Contact with Leads is a surface mount magnetic contact with leads instead of terminals. It’s also a member of the series of commercial contacts.

All commercial 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’re regularly testing all of your commercial contacts, your property may not be protected if you’re using the wrong commercial contact and it’s installed outside. Use these commercial 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.

Unlike other contacts that use terminal screws for wiring connections, the Commercial Contact with Leads has a 6’ CLII cable lead with (2) wires which you would use to wire to your zone circuit (make sure to use a wire connector as well). The internal reed switch for the Commercial Contact with Leads is a Form A, SPST, normally closed contact.

This contact has many of the features found in other commercial contacts. In addition to the surge protection, it also has an epoxy sealed case to protect it from water or corrosion. Also, the Commercial Contact with Leads 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 this contact’s wide gap, you can be confident that all alarms triggered are real emergency events.
