The Redi-Reset-MC Chain operator is designed
for use on Alpine Fire Doors and they safely
control fire door closing speeds and eliminate
the dangers associated with resetting spring tension
as with a conventional chain or crank operator.
Brake release activation allows the door to close
while routinely testing the governing closing system.
Normal or automatic closing speed of the
door is safely controlled and will not exceed 9”
per second. The fusible link activation is standard,
Alarm activation with the use of a fail-safe
release device is available as an option.
The Redi-Reset-MC Chain operator is available
for fire doors up to 30’ wide by 24’ high. This
operator is highly recommended for fire doors
that are installed and have exposed guides. The operator will safely stop the door curtain at any position
and will not backwind. Costly power wiring to the opening is not required.
A major benefit with the Redi-Reset-Chain operator is that after the fire door closes upon receipt of a signal
from a fusible link or an alarm activation there is no need to adjust the spring for the spring tension is never
released.
Any downtime associated with the testing of this operator is minimal. The fire doors are easily
reset to the open position within minutes by facility personnel.
Note: The Alpine Redi-Reset II Manual Chain Operator is compatible with Alpine’s Auto Fire-Tite,
Auto Fire-Shut, Auto Smoke Fire-Tite, Auto Fire-Tite Hi-Rise, and Auto Fire-Storm Model Doors.
