After installing and adjusting the door opener, photocells can be
installed.
The installation instructions are included with the photocells.
The optional photocells ensure that the door is open, or
remains open, if people, especially young children, are in the
door area.
By means of the photocells, a closing door is opened or an open
door is obstructed from closing, if a person located in the door area
interrupts the sensor beam.
Photocells are particularly recommended for families with young
children.
