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

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.
Where a door has never had photocells, any extra wiring needed is priced before we come out.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.

How does it work in Woolwich?

Rules that apply in Woolwich

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 Woolwich: questions

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

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 Woolwich visit date is confirmed in writing.

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 Woolwich?

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

Do you cover Woolwich?

Yes. Woolwich is part of the area we cover in Greater London, including SE18, SE7 and SE28. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

How many times will a battery backup open the door?

It depends on the unit, the motor and the size and weight of the door. A battery backup is designed for a limited number of cycles in a power cut, not for running the door for days. If you need the door after the battery runs down, use the manual override as the manufacturer's instructions describe.

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.
