Raynor FireHoist™ fire door operators are UL listed for use with Raynor FireCoil™ fire-rated doors, as well as for retro-fit applications where existing fire doors require new operators. Available in a variety of horsepower options, Raynor offers helical, spur and planetary gear drive systems. All models are c-UL-us listed and housed in a NEMA I enclosure.
All operators feature an internal release device and governor system to control the automatic closing of the door. The compact low profile design ensures that no additional clearance above the top of the door coil is required, saving space. If an approved monitored reversing device is not connected, the operator will require constant pressure on the close button, to close the door.
