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

Where a door has never had photocells, any extra wiring needed is priced before we come out.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.
The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.

How does it work in Lerwick?

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 Lerwick

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. Part P does not apply in Scotland, but electrical work must meet BS 7671 and the Scottish building standards where it forms part of building work.

Battery backup and safety upgrades in Lerwick: questions

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

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 Lerwick visit date is confirmed in writing.

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

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

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

Yes. We repair roller garage doors of any make in Lerwick and across ZE1, 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.

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 a battery backup be fitted to a manual roller door?

No. A manual door has no motor or control box for a battery unit to power, because springs in the barrel balance the curtain and you lift it by hand. If you'd like powered operation, a manual-to-electric conversion may be possible when the curtain, barrel, box and guides are sound and compatible.
