The Alpine Redi-Reset-GC unit combines
the ease of testing/resetting and controlled automatic
closing with manual chain operation on
Alpine Fire doors.
Redi-Reset GC is designed with a combination
chain operator/controlled closing system
that eliminates the reliance of a complex spring
release mechanism and complicated reset procedures.
The door is held open by a locking mechanism
that is tied into a factory supplied padlockable
guide mounted test handle and fusible link
system. By using the test handle or melting the
fusible link will release the locking mechanism,
disengages the hand chain operator and engages
the adjustable governing mechanism, all of these
components are a part of a compact operating
and closing system.
The door will close at a controlled rate of descent not to exceed 9” per second. To reset for normal
chain operation, simply re-engage the test handle or replace the fusible link. The Redi-Rest-GC unit can
be tied into a fire alarm system or local detectors with the use of a release device. If the operator is activated
by an alarm asignal, simply reset the operator by re-inserting the draw bar at the release device.
The door is then ready for normal use or emergency automatic closing.
Redi-Rest-GC is also ideal for fire doors that do not require the convenience of a motor operator.
Resetting is quick and easily performed by facility personnel. Access to the hand chain is required especially
if the guides are recessed in a wall.
