IR SENSOR INSTALLATION
Mount the IR sensor in a position (ceiling or wall) where it will be convenient to see
all the Retracta movements whilst maintaining good line of site with the IR sensor.
Do not place any obstruction in front of the sensor as this will prevent operation. Drill
a (16mm) (5/8") diameter hole. Pass the sensor through the hole and secure it using
the C clip. Connect the cable to the IR sensor input socket number 1 on the
Retracta unit.
IR sensor has 2 coloured led’s: Green = In programme mode, Red =
will show each time a button is pressed on the remote.
