Rixson FM-972U Overhead Door Release Mechanism

Rixson FM-972U Overhead Door Release Mechanism is a 24V DC, aluminum-finish release designed for overhead doors in commercial and industrial settings. UL-listed as a substitute for fusible links, it supports overhead-door applications such as overhead rolling doors, guillotine doors, fire dampers, and self-closing windows where a certified electrical release is required. This unit is part of Rixson's electromagnetic door holder/release family and is installed in the overhead door hardware to provide a controlled release in safety-critical or access-control installations, with a durable aluminum finish that withstands high-cycle usage. Documentation for overhead installation, including FM-972U/FM-973U installation instructions, guides proper mounting and wiring to ensure reliable performance. Typical applications include fire-rated door assemblies and other overhead door systems in warehouses, retail facilities, and service environments that require a code-compliant, UL-listed release solution.
