LiftMaster LM21AFCB Advanced Fire Control Release Device

The LiftMaster Fire Control LM21AFCB Release Device is a UL/ULC-listed normally energized, fail-safe device incorporating state-of-the-art electronic control circuitry.

This release device is designed for manual doors or motorized doors incorporating a reversing electric safety edge to create an automated door closing system, and in conjunction with a temperature fuse link system.

The high-performance control panel responds to emergency conditions generated from an automatic initiating device. Upon activation, the device will then automatically close a motorized door or mechanically release a door in the absence of motorized operation.
