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

Where a door has never had photocells, any extra wiring needed is priced before we come out.
The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.

Rules that apply in Braintree

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 Braintree: questions

Do you charge more for Braintree than other towns in Essex?

No. Guide prices are the same for Braintree as for anywhere else we cover in Essex. 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.

Do you cover Braintree?

Yes. Braintree is part of the area we cover in Essex, including CM7 and CM77. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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

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

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.

Do I still need the manual override if I have a battery backup?

Yes. A battery unit covers a limited number of cycles, and it can run down during a long power cut or as the battery ages. Keep the override handle somewhere you can find it in the dark, and make sure everyone who uses the garage knows where it is and how it works.

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.
