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

We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
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.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.

Rules that apply in Warminster

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 Warminster: questions

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

Yes. We repair roller garage doors of any make in Warminster and across BA12, 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 Warminster?

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 Warminster visit date is confirmed in writing.

Do you charge more for Warminster than other towns in Wiltshire?

No. Guide prices are the same for Warminster as for anywhere else we cover in Wiltshire. 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.

Can I get a price for Warminster 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.

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.
