The Alpine Redi-Reset-NF operator provides high quality automatic fire door closing control and eliminate the hassles of mechanical resetting. This operator system is available for both Fire doors and Counter Fire doors. The Redi-Reset-NF never needs to be mechanically reset. The operator will
close the fire door without releasing spring tension or disengaging the motor operator. Fire door closing speed will not exceed 9”
per second.
Redi-Reset-NF operator systems utilize a fusible link release device which is connected to a sash chain. Because of this automatic closing feature, a sensing edge is required to react to a possible obstruction in
the opening. After the alarm systems are cleared and power is restored the resetting of the operator is completed at floor level with
the touch of the “open” button on the control station. The fire door is now ready for both normal and or emergency operation.
A key benefit of the Redi-Reset-NF operator system is that it can be activated by a fusible link or thermal sensors, fire alarm systems or smoke detectors without the need for a mechanical release device. Door operator testing is completed quickly and easily.
