What should I know about battery backup and safety upgrades in Newton Mearns?

The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.

How does it work in Newton Mearns?

On the day, the upgrade is fitted and the door is tested. If anything else needs attention, the parts are quoted before they're fitted.

An electric door needs a power supply near the roller box. Part P does not apply in Scotland, but electrical work must meet BS 7671 and the Scottish building standards where it forms part of building work.

Battery backup and safety upgrades in Newton Mearns: questions

Will you fix the door on the first visit?

A fault can sometimes be found and put right on the first visit, but we never promise it. If a part needs ordering, we quote for it first, make the door safe where we can, and confirm the return date in writing.

Do you repair roller doors you did not fit in Newton Mearns?

Yes. We repair roller garage doors of any make in Newton Mearns and across G77, G76 and G46, where parts are available. If a part is no longer made, we tell you what will fit instead, or price a replacement door if that is the better option.

Can I get a price for Newton Mearns without anyone visiting?

Yes. The guide price tool takes four steps and gives a range for your opening and door type. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.

What should I do while I wait for a visit in Newton Mearns?

If the door is stuck part-open, keep people, pets and cars clear of it and switch off the power at the isolator if it is safe to reach. Do not force the curtain or open the roller box. Your Newton Mearns visit date is confirmed in writing.

How many times will a battery backup open the door?

It depends on the unit, the motor and the size and weight of the door. A battery backup is designed for a limited number of cycles in a power cut, not for running the door for days. If you need the door after the battery runs down, use the manual override as the manufacturer's instructions describe.

Do I still need the manual override if I have a battery backup?

Yes. A battery unit covers a limited number of cycles, and it can run down during a long power cut or as the battery ages. Keep the override handle somewhere you can find it in the dark, and make sure everyone who uses the garage knows where it is and how it works.
