Garage door safety sensor wiring?
I believe it is an infrared sensor with two wires on each. I have wired them to a 120V plug and the LEDs on them turn on and my motor spins slightly (probably just because it is a 120V motor and it's not getting enough electricity) but I try to line up the sensors and they do nothing different even when crossed. What I want to happen is for the motor to remain off until the beam is crossed. Once crossed I want it to spin and to keep spinning until I disconnect it. I would really like to put an alarm on it so when crossed an alarm goes off. Does anyone know the additional things I need and how to wire them? Thanks
