George Risk Industries 55F-12-W-BA Mini Flange Contact

Product Description

The George Risk Industries 55F-12-W-BA is a mini flange surface contact designed for use in security and access control wiring applications. Surface contacts are electromagnetic or mechanical sensing devices mounted at door and window frames to detect open or closed states and transmit that status to an alarm or access control panel. The 55F-12-W-BA features a white finish and a mini flange form factor, making it suitable for installations where a low-profile, clean appearance is required. Installation is typically performed by security system technicians or licensed electricians working on low-voltage alarm circuits.

This surface contact is intended for residential and light commercial security system applications. It mounts directly to the surface of a door frame or window frame without requiring a routed recess, simplifying installation on finished trim and hollow-core doors. The white finish blends with standard painted door and window trim commonly found in residential settings. It ships as a single unit.

Installation Notes

Surface contacts are installed by licensed security system technicians or low-voltage electricians in accordance with applicable local codes. Disconnect or power down the alarm panel before wiring the contact leads to avoid nuisance alarms or damage to the control board. Align the contact and magnet components according to the manufacturer data sheet to ensure reliable actuation at the specified gap distance. Follow all applicable NFPA 70 (NEC) low-voltage wiring requirements for the jurisdiction.
