What should I know about battery backup and safety upgrades in Letchworth Garden City?

You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
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.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.

Rules that apply in Letchworth Garden City

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 Letchworth Garden City: questions

What should I do while I wait for a visit in Letchworth Garden City?

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 Letchworth Garden City visit date is confirmed in writing.

Do you charge more for Letchworth Garden City than other towns in Hertfordshire?

No. Guide prices are the same for Letchworth Garden City as for anywhere else we cover in Hertfordshire. The written quote reflects your opening and the door you choose, not your postcode, apart from islands and remote areas where any travel cost is shown in advance.

How much is a visit in Letchworth Garden City?

Prices for battery backup and safety upgrades start from £99 inc VAT, and the price is agreed before anyone comes out. Any parts not covered by that price are quoted before they are fitted, so you can decide on the spot. The guide prices are the same in Letchworth Garden City as elsewhere we cover.

Can I get a price for Letchworth Garden City 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.

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.
