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

Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.
Never tape over, bridge or bypass a safety device to make an electric roller door close.
The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.
Photocells can often be added to doors that only have a safety edge, if the control box allows it.

Rules that apply in England

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 UKCA or CE marking, as the Supply of Machinery (Safety) Regulations 2008 require.

Electrics

An electric door needs a power supply near the roller box. Electrical work must meet BS 7671, and in England some domestic electrical work is notifiable under Part P, so it is done by a registered competent person or signed off by building control.

Questions about safety edge and photocell repairs in Cornwall

Which towns do you cover in Cornwall?

We cover Cornwall, including Redruth, Falmouth, St Austell and Truro. Every town has its own page with local details, and you can start a guide price for any postcode in Cornwall online.

How do I book a visit in Cornwall?

Tell us what the door is doing using the form on this page, by phone or on WhatsApp. We confirm the visit price before anyone comes out, then confirm the date in writing.

Can I get a price without anyone visiting?

Yes. The guide price tool takes four steps and gives a range for your opening and door type, or the visit price for a repair. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.

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.
