What range does the remote control operate the door from?

Electric insulated garage doors work by sending an encoded radio signal from the remote control to the control box to tell it to open and close at the required time. The distance from which this can be done will vary depending upon if any objects are in the way or you are inside a building.

We recommend that the safest way to operate the door is to do so by line of sight. By this, we mean that it should only ever be operated when you have a clear view. This way, you can be certain that no objects or more importantly, children are near to it when it closes. As a large heavy moving object, a garage door has the potential to cause injury. It is therefore essential that children are not allowed to play with the remote.

How long does the courtesy light stay on for?

The control box will feature a courtesy light to ensure the homeowner accesses a lit garage space. This light will automatically switch on as the door opens and will stay on for a period of approx 90 seconds.

What space do I require to install insulated roller garage doors?

Please refer to the Technical Specification page.

When should I service my insulated roller door?

Roller doors should be serviced according to the manufacturer`s guidelines. Most times a 12-18 month service schedule is more than adequate.

Please be aware that automatic doors are classed as a machine and therefore must comply with specific legislation. If you plan on using an insulated roller garage door in a work environment, it is the law that you carry out regular inspections and keep a record to show you are compliant.

Do I need to lock an automatic roller door?

Most automatic doors do not have a key lock. Instead they feature auto-locks that actively engage when closed to prevent the curtain being forced from the bottom. In addition to this, the control box is fitted with a 94db ear piercing alarm that will sound should someone try to force entry.

Should I wash my garage door?

To keep the door in good order therefore prolonging its life, it should be cleaned every few months to remove any grime and dirt. Use only a mild household detergent and soft cloth or sponge. Also remove dust and debris from the mechanical parts inside the garage.

What happens if my automatic roller door closes and hits an obstruction?

We take safety extremely seriously here at Roller Doors Ltd. That is why we only supply insulated garage roller doors that feature a safety device along the bottom leading edge of the door. Known as a “safety edge” it is designed to stop the door the instant it comes into contact with an object.

All the doors we supply are fully compliant with the legislation relating to force limitation on roller doors fitted with a tubular motor.

Please note that the market is flooded with inferior quality products. Although such items may look like a great deal, they are more than likely only fitted with a single photo cell and cheap imported motors. Single photo cells alone do not comply with legislation as the full coverage of the path of travel cannot be achieved because it only sends out a narrow beam around 150mm from the floor. Legislation states the whole of the opening must be protected.

Can I operate the door in the event of a power failure?

In the event of a power failure, the door can be operated from inside using the manual release mechanism to crank the curtain open and closed. This is only possible from inside the garage unless an added external manual release is purchased.
