Universal CR-2149 - Safety Beam Sensors for Garage Door Openers Review

This works fine and was easy to install, but there were only two terminals on one sensor where my old sensor had four wires connected. The installation instructions said nothing about this so I had to use trial and error to figure out how to connect it. If you have the same problem, simply connect both "+" wires from the old sensor to the "+" terminal on the new sensor and both "-" wires from the old sensor to the "-" terminal on the new sensor.
