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

Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.

How does it work in Antrim?

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 Antrim: questions

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

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 Antrim. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

Do you cover Antrim?

Yes. Antrim is part of the area we cover in County Antrim, including BT41. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

How much is a visit in Antrim?

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 Antrim as elsewhere we cover.

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

Yes. We repair roller garage doors of any make in Antrim and across BT41, 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.

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.
