The IBC mentions Limited Area sprinkler systems with a veiled
reference being 20 sprinklers or less. However, there is no formal
definition or description as to what they are or where they are
allowed. Any thoughts or experience with this? I have a proposal on
my desk for a partial system
I have done a few of these type systems. Usually the ones I have done
involve a mechanical room with a gas furnace or an elevator equipment room.

Not an issue. In a birdcage the riser is not serving and area greater than
5000 sq.ft. (usually). There may be dozens or dozens of dozens of risers.
And it's not exactly clear in the definitions but in a birdcage the vertical
piping more closely matches the definition of a branch line.

I've done a few of the partial systems according to NFPA 101, but as
you say, it is just a couple of heads in a space. That tops out a 6
sprinklers. However, the IBC one appears to go to 20. The one I have
been asked to look at is 18.

This product commodity falls within the same parameters as boat storage - there

Actually, the IBC section on limited area sprinkler systems goes up to 19 heads

The only hole in the thinking of the experts is their opinions are based
on WAG not SWAG to my knowledge. I'm not suggesting they are wrong. I'd
trust their knowledge a bit more if they had some test data (which doesn't
exist) or at least some examples of fires and the outcome. Sure would be
As identified by Karen, the IBC allows some locations (such as furnace
rooms) to be individually protected (or a higher degree of
separation). This is providing protection from this room to the rest
of the building. So I guess the sleeping room is such a hazard that

1. If you can get the insurer to spec the design, good.
2. If the EOR spec's the design, protect yourself as best you can. Refer all
questions of changes to them so they assume responsibility for every
decision.

And by sprinklering the rooms??

While I am not aware of any published case studies per-se, I do know you can
go to manufacturers' websites for good information. For Spears, check out
