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

Where a door has never had photocells, any extra wiring needed is priced before we come out.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.

How does it work in Barnet?

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.

Rules that apply in Barnet

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.

Battery backup and safety upgrades in Barnet: questions

Can I get a price for Barnet 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.

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

Yes. We repair roller garage doors of any make in Barnet and across EN5, EN4 and N20, 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.

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

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 Barnet visit date is confirmed in writing.

Do you cover Barnet?

Yes. Barnet is part of the area we cover in Greater London, including EN5, EN4 and N20. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

Can safety devices be added to an older electric door?

Usually, if a compatible safety edge or photocells are available for the control box. Some older systems need extra wiring or a replacement control box first. Tell us what's on the control box label and we'll confirm whether it can be done, and the price, before booking the visit.
