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

You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.

Rules that apply in Canterbury

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 Canterbury: questions

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

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

Can I get a price for Canterbury 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 cover Canterbury?

Yes. Canterbury is part of the area we cover in Kent, including CT1 and CT2. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

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.
