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

A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.
The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.

How does it work in Lisburn?

We confirm the visit price and the cost of the battery unit, safety edge or photocells. The visit is booked, with the date confirmed in writing once an engineer is available.

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.

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.

Battery backup and safety upgrades in Lisburn: questions

What should I do while I wait for a visit in Lisburn?

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 Lisburn visit date is confirmed in writing.

Do you charge more for Lisburn than other towns in County Antrim?

No. Guide prices are the same for Lisburn as for anywhere else we cover in County Antrim. The written quote reflects your opening and the door you choose, not your postcode, apart from islands and remote areas where any travel cost is shown in advance.

Do you cover Lisburn?

Yes. Lisburn is part of the area we cover in County Antrim, including BT27, BT28 and BT17. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Do you repair roller doors you did not fit in Lisburn?

Yes. We repair roller garage doors of any make in Lisburn and across BT27, BT28 and BT17, 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 safety devices be added to an older electric door?

Usually, if a compatible safety edge or photocells are available for the control box. Some older systems need extra wiring or a replacement control box first. Tell us what's on the control box label and we'll confirm whether it can be done, and the price, before booking the visit.

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.
