Raynor FireHoist FGH fire door operators offer 1/2 hp, 1 hp, 1-1/2 hp, 2 hp and 3 hp in line gear reducer option providing for an integrated fire door system. Resetting of the operator is as easy as reconnecting the fusible link release cable and then activating the open control to reset the door. The FGH models are also available for retro fitting existing fire doors by eliminating all the components that typically fail with an operator. Other release devices can be added to the system for detector/alarm inputs and loss of power.
