The Genie Replacement Safety Beams replace most Genie infra-red photocell 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. The Safety Beam is a Non-contact reversing system that places an invisible infrared beam across the door opening that causes the door to reverse upward when anything passes through the beam.
These will not work with openers not originally equipped with infra-red sensors. The GSTB-BX 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 is not needed to connect these sensors to the sensor wires.
