CBC 1011.4- Internally Illuminated Exit Signs UL 924

[miguele3]

A co-worker and I are having a disagreement. I think we should make special mention of UL 924 regarding exit signs on our drawings. He says since it covered by the code it is not necessary. My point is that the UL 924 is a change to the code and we should make special mention of it. Do most electrical contractors know about UL 924 or is it unnecessary as all manufacturers comply?

If they comply with the code, they will comply with UL 924.

They by state statute, must comply with the code, not UL 924.

Internally illuminated is not required by the IBC, correct? I am unfamiliar with the UL

I just reviewed 924. Where is the change?

Not necessarily a "change" in the code just over the past 10 years its been working its way into the text. The codes just used "listed" and UL has worked hard getting their standards mentioned and included in the language text. Personally, I would think as long as the equipment you plan to note with the "note" is indeed listed to ANSI/UL 924 and is included in the FWBX catagory guide and marked for viewing ranges 50, 75 or 100 feet, it's a good thing

There are only a few that meet the 100' distance and all other charging light criteria the standard's testing requires.

The CA building code does indicate that there is a change, But only they know for sure...

I sometimes make comments on plans to assure it stands out.

That way when it comes time to inspect you hear less of, " I did not know that was in the code"""

It does not hurt

Stands out to whom? The draftsman or the electrician?

The more crap the designer puts on the plans the more the guys in the field miss stuff……

I am the ahj reviewing the plans and having to inspect the stuff

so hopefuly it stands out to someone building the thing, and also I try to visit very early on and go over the comments also.

The reference to UL 924 belongs in the specs, not on the drawings.
