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

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.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
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 Dumbarton?

Rules that apply in Dumbarton

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 Dumbarton: questions

Do you charge more for Dumbarton than other towns in Dunbartonshire and Argyll?

No. Guide prices are the same for Dumbarton as for anywhere else we cover in Dunbartonshire and Argyll. 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 message you a photo of my garage in Dumbarton?

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

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

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 Dumbarton visit date is confirmed in writing.

How much is a visit in Dumbarton?

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 Dumbarton as elsewhere we cover.

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.
