Centurion RDO II Roll-Up Garage Door Motor
A compact 24V DC roll-up garage door operator with battery-driven operation, electronic collision sensing and CENTURION code-hopping remote control.
The RDO II is designed for domestic roll-up garage doors where quiet operation, backup power and a compact side-mounted operator are important.
A Dedicated Motor for Domestic Roll-Up Garage Doors
The RDO II is not a general-purpose sectional-door motor. It is intended for domestic roll-up garage doors and should be selected after the door size, balance and condition have been checked.
RDO II Technical Data
The values below are based on CENTURION manufacturer literature for the RDO II. Final installation suitability still depends on the actual roll-up door.
Features That Matter in Everyday Roll-Up Door Use
Battery-Driven Operation
The RDO II is designed to continue operating when mains power is unavailable, subject to the condition and charge of the installed battery system.
24V DC Motor
The high-torque DC drive is intended to provide smooth, quiet operation for domestic roll-up garage doors.
Electronic Collision Sensing
The operator detects abnormal resistance during travel and can stop and reverse when an obstruction is encountered.
Code-Hopping Receiver
CENTURION code-hopping technology changes the transmitted code to reduce the risk associated with simple fixed-code copying.
Auto-Close Capability
Auto-Close can be configured where the installation and safety equipment are suitable. Safety beams are strongly recommended.
Made for Roll-Up Doors
The operator is designed around the roll-up door system rather than requiring the long ceiling rail used by many sectional-door motors.
Battery Backup Is Useful — Correct Door Setup Is Essential
A garage door motor should automate a door that already moves correctly. It should not be used to force a stiff, damaged or badly balanced roll-up door.
Power During Outages
The RDO II is battery driven and charged from the mains supply. That means normal operation can continue during a power interruption while usable battery capacity remains.
Safety Before Automation
The roll-up door should travel freely before the motor is installed. Safety beams are recommended where Auto-Close or automated closing is used.
Useful RDO II Accessories & Controls
The final accessory combination depends on how the garage is used and which functions are needed.
