Potter Electric Signal Co. Us 4350052 Recessed Door Contact

Product Description

The POTTER ELECTRIC SIGNAL CO. 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.

This 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.

• 3/4 inch recessed body fits standard door frame bore applications
• Brown finish for a discreet, finished appearance on wood or painted frames

Compatibility

Installation Notes

Installation should be performed by a licensed fire alarm or low-voltage security technician in accordance with NFPA 72 and applicable local codes. De-energize the fire alarm or security panel zone before installing or replacing the contact to prevent false alarms or panel faults. A standard 3/4 inch drill bit is used to bore the mounting hole in the door and frame. Verify the operating gap between the magnet and contact body meets the manufacturer specification before closing up the installation.
