What should I know about battery backup and safety upgrades in County Down?

The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
Where a door has never had photocells, any extra wiring needed is priced before we come out.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.

Rules that apply in Northern Ireland

Powered door safety

Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and CE marking, which is the marking that applies to machinery placed on the market in Northern Ireland.

Electrics

An electric door needs a power supply near the roller box. Part P does not apply in Northern Ireland, but electrical work must still meet BS 7671 and be carried out by a qualified electrician.

Questions about battery backup and safety upgrades in County Down

Can I get a price without anyone visiting?

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

Are guide prices the same across County Down?

Yes. The guide prices are the same in every town in County Down. The written quote reflects your opening and the door you choose, not your postcode.

How do I book a visit in County Down?

Tell us what the door is doing using the form on this page, by phone or on WhatsApp. We confirm the visit price before anyone comes out, then confirm the date 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.
