Liftmaster LM21AFCB 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 to be used with manual doors or motorized doors incorporating a reversing electric safety edge to create an automated door closing system, and is also used in conjunction with a temperature fuse link system.
