US 4350052 is a recessed magnetic door contact switch used in fire alarm and security detection systems. Designed around a Form C contact configuration, it provides both normally open and normally closed switching in a single unit, giving installers flexibility in circuit design. The 3\/4 inch recessed form factor allows it to be mounted flush within door frames or door edges, keeping the device concealed while maintaining reliable gap sensing. This contact is sold as an individual unit and is a standard component installed by fire alarm technicians and security system integrators.\u003c\/p\u003e\n\u003cp\u003eThis recessed door contact is suited for residential and light commercial fire alarm and access control installations. It is typically installed in wood or hollow-metal door frames where a low-profile, concealed switch is required. The brown finish allows it to blend with common door and frame finishes. It is appropriate for use in supervised fire alarm loops or security zones where Form C switching is specified by the system design or by the authority having jurisdiction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eForm C contact configuration provides both normally open and normally closed output in one device\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch recessed body fits standard door frame bore applications\u003c\/li\u003e\n  \u003cli\u003eBrown finish for a discreet, finished appearance on wood or painted frames\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging for individual replacement or new installation\u003c\/li\u003e\n  \u003cli\u003eClassified as a fire accessory for use in supervised alarm circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style recessed door contact switch for use in fire alarm and security system applications requiring a 3\/4 inch Form C recessed magnetic contact.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed fire alarm or low-voltage security technician in accordance with NFPA 72 and applicable local codes.
