With the SDO4, that experience begins the moment that you open your garage door.
With whisper-quiet operation and movement, the SDO4 garage door operator for tip-up and sectional doors lets you know you’re home.

An SDO4 to suit your door
The SDO4 comes in two different models, making it suitable for virtually any size domestic garage door. Choose the T10 for smaller doors up to 12 square metres, or automate your bigger door with the powerful T12 model.

Battery-driven – ALWAYS on
You need to be somewhere in a hurry. The power goes out. You’re going nowhere.
Unless you have the SDO4, that is. The SDO4 switches seamlessly between mains and battery power in the event of a power outage, so it’s always on. You can even use solar power to charge the system.

Reliable DC motor
Our 24V geared DC motor provides enough power to move even the largest door quietly and reliably.

Adaptive anti-crushing control
The SDO4 was designed with safety in mind! The built-in anti-crushing circuitry will cause the door to stop and reverse if an obstruction is detected, helping to prevent serious damage or injury.

Ease of installation, adjustment and setup
Ready. Set. Go! The drive unit slides into the rail and the control box slots into position at the back, it’s as simple as that. Additionally, the built-in LED display and colour-coded buttons together make it a delight to configure settings and toggling between the operator’s many unique features couldn’t be easier.

Total security at the press of a button
The hand that rocks the cradle is the hand that rules the world… and so is the hand that controls Holiday Lockout Mode! This onboard high-security feature allows you to electronically lock your garage door by pressing one of the Wireless Wall Switch or remote control buttons, giving you total control of who gets in.

Lock in any position
For increased security, the Manual Override can be disengaged and then re-engaged in any position. If you’re going away on holiday you can also electronically lock your SDO4 so that not even a learned-in remote control can operate the door.

Autoclose
Look, Ma, no hands! If you forget to close your garage door, your SDO4 will do it for you – if you’ve activated the Autoclose feature. Or maybe you’re moving stuff out of your garage and need the door to remain open – overriding Autoclose is as easy as pressing a button!

Onboard receiver with code-hopping security
A home security system that fits in your pocket. Our four-button code-hopping remote control utilises the same technology found in top of the range vehicle security systems and can control your SDO4, home alarm system, automatic gate motors and whatever else you need to feel safe. Rest easy, knowing there’s a CENTURION standing guard.

Door Service Monitor
Using adaptive load sensing technology, our Door Service Monitor keeps an eye on things and a courtesy lamp will flash and a buzzer will sound when your door springs are worn out and need maintenance.
