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

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

Rules that apply in Prescot

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.

Safety edge and photocell repairs in Prescot: questions

Will you fix the door on the first visit?

A fault can sometimes be found and put right on the first visit, but we never promise it. If a part needs ordering, we quote for it first, make the door safe where we can, and confirm the return date in writing.

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

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

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

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 Prescot visit date is confirmed in writing.

Can I get a price for Prescot 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 bypass the photocells to get the door shut?

No. Bypassing, bridging or taping over a safety device removes the protection that stops the door closing onto a person, pet or car. If the door won't close, switch it off at the isolator, keep the area clear and request a visit. Tell us if you're concerned about security when you get in touch.

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.
