While a bit further away than most I see, I think the critical dimension is how far the sensor is from the floor.
As long as the sensor reverses the door, and it's 5-6" from the floor, I'm OK with it.

It should be inline with the door IMHO....I would CMA and write it up.

I have never seen a requirement to mount the sensor on the rail, and that looks like the supplied bracket. I would mention the hanging wire though.

Height off the floor is the element being inspected. If sensor is on rail or not should not make any difference. I agree with Jim in that care should be taken to protect the wire ... or any wire so it does not become a trip hazard or accidental hook by something.

I'm not sure what James meant by "It should be inline with the door IMHO", since it is obviously in line with the door.

I just pulled out the installation manual for my Genie opener. It is specific about the height. "Must be no more than 5" and less than 6" above the floor". It does not specify a side distance. It does say to install to inside door framing (not rail/track), but also says you can mount to the floor with brackets (not provided).

Since the opener will not work unless the sensors are installed in line with each other, I'm thinking that the side to side distance is not critical as long as they line up and operate correctly.

Of course the wires should be out of the way.

As it is ... it can't be in-line with the door. If it were, the railing would prevent the door from coming down.

I looks to be installed between the railing and the wall...

If that were the case, I would think this would not be right as a small child could actually be under partly of the door and not be between the rail and the wall.

Not only that, but if in line with the door, the door itself would cut the beam and reverse, you'd never be able to close the door.

I should have said on the rail..sorry about that!

Dan,
Did the sensors work and reverse the door?
Did they clear the door? (If they worked, I guess they cleared the door)

By the way, they probably are set too high anyway.

The auto sensors should be no less than 4" from the floor and no higher than 6" above the floor, correct? At least that's the criteria I've always used....now.....is that from code or manufacturer spec? I can't find it in the code.

Thanks,

Brian

Go to the DASMA (Door & Access Systems Manufactureser Association) website and look at the Tech Data Sheets.

Specifically TDS #167, item #8, TDS #363, and TDS #364

Thanks, Bruce.

What about the minimum height, according to the spec the sensors have no minimum height only a maximum height from the floor. Thoughs?

Brian,

My take is the No Higher than 6 inches as that is the maximum.

Like 4 inches would be the maximum allowed space between Railing Balusters and no minimum.
