George Risk Industries Inc. 150MFTW Surface Contact

Product Description

The GEORGE RISK INDUSTRIES INC. 150MFTW is a surface-mount magnetic contact with integrated terminals, designed for use in security and alarm system installations. This type of contact operates as a switching element that detects the open or closed state of a door, window, or access panel. It ships as a single unit and is typically installed by security system technicians or electricians performing low-voltage alarm work. The terminal configuration allows for direct wire connections, simplifying field wiring during installation.

Surface contacts in this category are used in residential and light commercial security applications. They are mounted directly to the surface of a door or window frame and the corresponding moving element, eliminating the need for recessing into the frame. The 150MFTW is suited for new construction installations and retrofit projects where surface mounting is the preferred or required method.

Key Features

• Surface-mount design for straightforward installation on doors, windows, and access panels
• Integrated terminals for direct field wiring without additional connectors
• Compact 0.5 inch form factor fits standard low-voltage alarm applications
• Sold individually, allowing single-unit replacement or incremental installation

Compatibility

Designed as an OEM-style replacement or new-installation component for standard surface-mount contact alarm circuits in residential and light commercial security systems.

Installation Notes

Installation is typically performed by licensed low-voltage or alarm system technicians in accordance with local codes and NEC guidelines for low-voltage wiring. De-energize the alarm circuit and verify the panel is in a disarmed or bypass state before beginning any wiring work. Ensure the contact and magnet halves are aligned within the manufacturer-recommended gap distance for reliable switching. Secure all terminal connections and test the circuit for proper open and closed states before closing up the installation.
