George Risk Industries 1100A-12-W Surface Mount Contact Switch

Product Description

The George Risk Industries 1100A-12-W is a surface mount magnetic contact switch wired in a closed-loop configuration and finished in white. Magnetic contact switches of this type monitor the open or closed status of a door, window, or access panel by detecting the presence or absence of a paired magnet. When the magnet separates from the switch body, the loop opens and triggers the connected control circuit. This switch is suited for low-voltage alarm and access-control wiring work and is sold as a single unit.

Surface mount magnetic contact switches are installed on the stationary frame of a door or window, with the magnet mounted on the moving sash or door edge. The closed-loop wiring configuration means the circuit is normally closed at rest and opens upon separation, which is the standard fail-safe topology used in intrusion detection, access control, and building automation panel wiring. The white finish allows the switch to blend with standard interior door and window trim in residential and light commercial installations.

Key Features

• Closed-loop wiring configuration for fail-safe intrusion detection and access control circuits
• Surface mount design simplifies installation on door frames and window casings without routing
• White finish suits standard residential and light commercial interior trim
• Sold as individual unit for single-point replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-installation component for surface mount magnetic contact switch applications in residential and light commercial door and window alarm or access control systems.

Installation Notes

Installation is typically performed by licensed alarm technicians or low-voltage electricians in accordance with applicable local codes and NFPA 72 requirements where intrusion detection is involved. De-energize the control panel circuit before connecting or disconnecting switch wiring. Mount the switch body to the fixed frame and the magnet to the moving door or sash, aligning the two components within the manufacturer-specified gap for reliable operation. Verify loop continuity at the panel before returning the system to service.
