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

The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.
Never tape over, bridge or bypass a safety device to make an electric roller door close.
Photocells can often be added to doors that only have a safety edge, if the control box allows it.
Photocells either side of the opening stop the door closing while anything is breaking the beam between them.

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.

Can photocells be added to a door that doesn't have them?

Often, if the control box has a connection for them. 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 photocells can be added, and the price, before booking. Our battery backup and safety upgrades page covers adding devices.
