Alpines Redi-Reset® FDCL battery release system incorporates a fire door operator to provide automatic fire door closing while eliminating the difficulties of mechanical resetting.
The Redi-Reset FDCL systems are available for use with rolling fire doors and rolling fire counter shutters. Normally, Redi-Reset FDCL systems function as standard a motorized door 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® FDCL 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 FDCL battery release operator system will never need to be mechanically reset. The operator closes the automatic closing doors without releasing any spring tension or disengaging the motor operator from the unit. The Redi-Reset FDCL 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 of this motorized door is once again ready for normal or alarm activation.
All the above features of these automatic closing doors make the Redi-Reset FDCL 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.
