Question

1. this pair of garage door sensors:

are positioned too close together
are positioned correctly
should be powered by larger gauge wiring
should be pointing at the garage door
should be positioned on either side of the door

Explanation:

Garage door sensors (photo - eyes) are typically installed on either side of the garage door (one on the left track, one on the right track) to create an infrared beam. In the image, the sensors seem to be on the same side, so they should be positioned on either side of the door. Option A: Being too close isn't the main issue here. Option B: They aren't positioned correctly as per standard installation. Option C: Wiring gauge isn't the problem shown. Option D: They should point at each other, not the door.

Answer:

E. Should be positioned on either side of the door
