What should I know about safety edge and photocell repairs in Folkestone?

Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
Never tape over, bridge or bypass a safety device to make an electric roller door close.
Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.

Rules that apply in Folkestone

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.

Do you charge more for Folkestone than other towns in Kent?

Why does my roller door reverse when nothing is in the way?

A door that reverses on its own while closing is often reacting to a safety device that thinks there's an obstruction. Dirty or misaligned photocells, a damaged safety edge, a loose cable or limits that have drifted can all cause it. Clean the photocell lenses and check the beam is clear, then request a visit if it continues.

How do I test my safety edge and photocells?

Follow the manufacturer's instructions for your door. In general, the test checks that the door stops or reverses when the safety edge meets an obstruction while closing, and that the door won't close while the photocell beam is broken. Keep people and pets clear while testing, and repeat the test monthly.
