Alpines Redi-Reset FDC system incorporates a Fire
Door Operator to provide automatic fire door closing while
eliminating the difficulties of mechanical resetting. The
Redi-Reset FDC systems are available for use with
Rolling Fire Doors and Rolling Fire Counter Shutter
Doors.
Normally, Redi-Reset FDC systems function as standard
motorized doors with push button activation and are capable
of closing the door in the event of a fire emergency.
Central alarm systems or local fire detectors can be wired
directly to the Redi-Reset FDC operator in order to signal
the door to close when in alarm eliminating the need for
an external mechanical releasing device.
Doors are
designed to automatically close by : power failure; high
temperature detection at the opening from fusible links or
electrical thermal sensors or by an active alarm signal.
Operator units that utilize back-up battery support can
remain open and fire ready during prolonged power outages
and can still close the door in the event of an alarm
signal or high temperature detection. Due to the automatic
closing feature of these systems, a bottom bar sensing
edge is required for detection of an obstruction in the door
opening.
The Redi-Reset FDC operator system will never need to be mechanically reset. The operator closes the fire door without
releasing any spring tension or disengaging the motor operator from the unit. The Redi-Reset FDC operator closes the door
electrically or mechanically at an average rate of speed of not more than 9” per second.
These operators are fail-safe by design
which means they are capable of responding to an alarm signal to close the door even in the event of a power failure. If any of
the following alarm conditions are present - restoration of power, cleaning the alarm signal, replacing the fusible link or resetting
the thermal sensors - simple activation of the “open” control station at floor level resets the door. The operator is once again
ready for normal or alarm activation.
All the above features make the Redi-Reset FDC operator system an ideal choice when used for larger size fire doors, fire-rated
units in recessed applications, units in areas susceptible to frequent power outages or any application where mechanical testing
and resetting is not practical.
