Smoke Control Panel without UL or any other NRTL listing?

Smoke Control Panel without UL or any other NRTL listing?

Smoke Control Panel without UL or any other NRTL listing?

(OP)
A UL 508a panel shop has been assigned to build a smoke control panel. They can't stick a 508a UL label on it, that is prohibited. UL 864, category code UUKL is what applies to smoke control panels. No panel shop can do UL 864 stuff, that is a standard that must be certified by submitting samples to UL and having extensive testing done.

Questions:

1) If the contractor for whom the panel is to be built gives a written waiver of responsibility for the non-label issue, would you build an unlabeled smoke panel?

2) If the local AHJ gives a written OK for the unlabeled smoke panel, would you build it?

Best to you,

Nothing in Section 909.16 in the 2009 International Building Code requires that the smoke control panel be listed.

Thanks stookey,

I couldn't find anything in there either, but NFPA 92 is being enforced:

6.4 Smoke Control Systems

6.4.1 Control systems shall be listed in accordance with ANSI/UL 864, Standard for Control Units and Accessories for Fire Alarm Systems, category UUKL, for their intended purpose.

Dave:

I can't offer much more because my jurisdiction doesn't adopt NFPA 92. We have over 100 high-rise buildings and most have some active smoke control systems.

Given the fact that even with a prescriptive design that smoke control systems are engineered, the jurisdiction should understand the panel is nothing more than a control component for a system that will activate and respond before the FD is dispatched.

Is this a high-rise or a large Group A occupancy?

Thanks again Stookey. I'm mostly in agreement with you.

The building is this thing: http://www.victorianweb.org/art/architecture/iron/...

Sort of an ancient covered shopping mall that's being turned into apartments called "micro-lofts." It's three stories high.

I'm going to go ahead and ask the fire marshal. But our company's attorneys will have the final say-so...

Best to you,

Interesting. If was the Fire Protection Engineer on the project, I would present the analysis of applying the requirements in International Existing Building Code to avoid the atrium smoke control system. I think I could persuade the code official to allow a more robust sprinkler design to avoid attempting to retrofit smoke control in that building.

Wish you were here, stookey.

Thanks tons for your input!
