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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteel construction for durability on metal door applications\u003c\/li\u003e\n\u003cli\u003e3\/4 inch form factor fits standard surface-mount door frame installations\u003c\/li\u003e\n\u003cli\u003eOpen loop contact configuration for zone circuit integration\u003c\/li\u003e\n\u003cli\u003eSold individually as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation contact for residential and light commercial door security and alarm systems requiring a 3\/4 inch steel surface-mount open loop contact.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed low-voltage security or alarm technicians.
