Replaces most GENIE infra-red photo cell systems.  These are the newest and most advanced sensors Genie now makes, replacing all previous sensors except the first generation ISR-3 wire connection beams.  Will not work with openers not originally equipped with infra-red sensors.  Beams have screw terminal connections and come with mounting brackets and complete mounting and wiring instructions.

These sensors have screw terminals instead of plug-in or push-in connections for the sensor wires.  The pig-tail sensor plug, shown below in Related Items, is not needed to connect these sensors to the sensor wires.
