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

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.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.

Rules that apply in Dorchester

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 Dorchester: questions

How much is a visit in Dorchester?

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 Dorchester as elsewhere we cover.

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

Yes. We repair roller garage doors of any make in Dorchester and across DT1 and DT2, 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 Dorchester?

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 Dorchester visit date is confirmed in writing.

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

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

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.

Can safety devices be added to an older electric door?

Usually, if a compatible safety edge or photocells are available for the control box. Some older systems need extra wiring or a replacement control box first. Tell us what's on the control box label and we'll confirm whether it can be done, and the price, before booking the visit.
