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

Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
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.

How does it work in Downpatrick?

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.

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.

Battery backup and safety upgrades in Downpatrick: questions

Can I get a price for Downpatrick 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.

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

Yes. We repair roller garage doors of any make in Downpatrick and across BT30, 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.

Do you cover Downpatrick?

Yes. Downpatrick is part of the area we cover in County Down, including BT30. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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

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 Downpatrick visit date is confirmed in writing.

Can a battery backup be fitted to a manual roller door?

No. A manual door has no motor or control box for a battery unit to power, because springs in the barrel balance the curtain and you lift it by hand. If you'd like powered operation, a manual-to-electric conversion may be possible when the curtain, barrel, box and guides are sound and compatible.

How often should I test the safety edge and photocells?

Test them monthly, following the manufacturer's instructions for your door. The aim is to confirm that the door stops or reverses when the safety edge meets an obstruction, and won't close while the photocell beam is broken. If either test fails, don't keep using the door until it has been checked, and request a visit.
