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

After fitting, the door is tested to check it stops and reverses as it should with the new devices.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
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 Limavady: questions

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 you cover Limavady?

Yes. Limavady is part of the area we cover in County Londonderry, including BT49. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

How much is a visit in Limavady?

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 Limavady as elsewhere we cover.

Can I get a price for Limavady 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.
