What should I know about safety edge and photocell repairs in Belfast?

A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.
After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.
Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
Photocells can often be added to doors that only have a safety edge, if the control box allows it.

How does it work in Belfast?

The engineer tests the circuit and replaces the faulty device, then tests the door. Any further parts are quoted before they're fitted.

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.

Safety edge and photocell repairs in Belfast: questions

Do you cover Belfast?

Yes. Belfast is part of the area we cover in County Antrim, including BT1, BT2 and BT7. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

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

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 Belfast visit date is confirmed in writing.

Why does my roller door reverse when nothing is in the way?

A door that reverses on its own while closing is often reacting to a safety device that thinks there's an obstruction. Dirty or misaligned photocells, a damaged safety edge, a loose cable or limits that have drifted can all cause it. Clean the photocell lenses and check the beam is clear, then request a visit if it continues.

How do I test my safety edge and photocells?

Follow the manufacturer's instructions for your door. In general, the test checks that the door stops or reverses when the safety edge meets an obstruction while closing, and that the door won't close while the photocell beam is broken. Keep people and pets clear while testing, and repeat the test monthly.
