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

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.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.

Rules that apply in Belfast

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 Belfast: questions

How much is a visit in Belfast?

Prices for battery backup and safety upgrades start from £99 inc VAT, and the price is agreed before anyone comes out. Any parts not covered by that price are quoted before they are fitted, so you can decide on the spot. The guide prices are the same in Belfast as elsewhere we cover.

Can I get a price for Belfast 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.

Can I message you a photo of my garage in Belfast?

Yes. Photos of the opening, the inside of the garage above the door and any existing door help us give a more useful guide price for Belfast. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

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

No. Guide prices are the same for Belfast 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.

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.

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.
