George Risk Industries 185-12-G Door Open Loop Contact

Product Description

The George Risk Industries 185-12-G is a steel door open loop contact designed for use in security and alarm systems. This surface-mount magnetic contact monitors the open or closed status of a door and signals the connected control panel when the circuit state changes. Constructed from steel, the 185-12-G is built for durability in light commercial and residential applications. It is sized at 3/4 inch, making it compatible with standard door frame installations. Security installers and low-voltage alarm technicians are the primary trade professionals who specify and install this contact type.

This contact is suited for residential and light commercial security system installations where reliable door monitoring is required. It is typically mounted on steel doors where a surface-mount form factor is appropriate. The open loop configuration integrates with standard alarm control panels that monitor normally closed or normally open zone circuits. Installers working on perimeter zone coverage commonly use contacts of this type for entry and exit door points.

Installation Notes

Installation is typically performed by licensed low-voltage security or alarm technicians. De-energize the alarm control panel zone circuit before making or breaking any wiring connections. Follow local low-voltage wiring codes and the alarm panel manufacturer wiring guidelines when integrating this contact into a zone circuit. Verify proper gap alignment between the contact and magnet after mounting to confirm reliable circuit actuation.
