Liftmaster AFB120 Fire Switch Red Box

Product Description

The LIFTMASTER AFB120 is a fire switch housed in a red enclosure box, designed for use in access control and door operator systems. The red box designation provides quick visual identification for fire and life safety applications, a requirement in many commercial and industrial installations. This component is typically installed by licensed door system technicians or access control professionals working on automatic gate operators, commercial door operators, or similar powered access equipment. The unit ships as a single assembly, ready for field installation.

The AFB120 fire switch is intended for commercial access control applications where a dedicated fire safety input is required. In the event of a fire alarm signal, the switch interfaces with the door or gate operator to trigger the appropriate fail-safe response per local fire and life safety codes. It is well suited for commercial buildings, parking structures, loading docks, and similar facilities where automatic access equipment must integrate with fire alarm systems.
