What should I know about battery backup and safety upgrades in Vale of Leven?

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.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.

Battery backup and safety upgrades in Vale of Leven: questions

Do you cover Vale of Leven?

Yes. Vale of Leven is part of the area we cover in Dunbartonshire and Argyll, including G82 and G83. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Can I get a price for Vale of Leven 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.

Can I message you a photo of my garage in Vale of Leven?

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 Vale of Leven. 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 Vale of Leven?

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 Vale of Leven visit date is confirmed 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.

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.
