Charles,
I would suggest that you might try the head of corporate
communications, but the VP of marketing or COO might be more
effective. That's what I have done in the past. Here's their media
web site with contacts http://www.swamedia.com/swamedia/. Good luck.
Haven't seen the commercial
Ok, amongst the voluminous amounts of dialogue I had missed the significant
little detail of the problem systems being primarily alarmed by pressure
switches on retard chambers.
Flow switch on wet, pressure switch on dry. Use the one appropriate for the
installation.
Forget the pressure
Rodney,
I was not as late into the conversation as it would seem. I actually sent
this a couple of weeks ago, but I had an unknown email server problem of
several weeks that got resolved on Friday. Recipients were not receiving
my emails. All my emails got sent out late.
Thanks for the
I am looking for some code help. According to NFPA 13 8.2.4 you can have
separate buildings that share a common roof, walls or passageway be
protected by one riser. Does anyone know if the IBC contradicts this? I have
an architect telling me I have to have a separate riser for each section of
not to belabor the point...
In my opinion, the importance of this discussion is the spririt of sharing
experience coupled with the fact that this configuration still exists out
there. While I agree that use of the flow switch is the preferred method..
there are those systems still out there
Charles,
I saw the commercial last evening. If you look closely, the chrome
pendent sprinkler installed in the fictitious office space was not
equipped with a glass bulb or a fusible link prior to the alleged
activation.

Has anyone had experience with sandblasting of a ceiling around sprinklers?
What kind of protection needs to be taken so that sprinkler heads are not
damaged (??) by the force of the sandblasting operation?
I am working on a scope where the owner wants to sandblast a ceiling and then
repaint.
What is the ceiling material?
What kind of sprinklers? Concealed? Flush? Recessed?
My first thought -- pull the sprinklers, install plugs (to protect the interior
of the piping from accumulation of grit) and reinstall after the blasting and
painting is done. Fire watch or remove all
I would remove the heads. If they're bulb type they're extremely fragile
anyway.
Why take the chance?

It depends upon the distance between buildings and the percent of open

Heads are just standard uprights. Ceiling is smooth with epoxy paint as far
as I know but has.
I am writing into the scope the need for a fire watch.

Daniel,
Maybe you could talk to the airline company and suggest that Tyco was
considering running an ad about how effective their fire protection
equipment (maybe Ansul foam) is on airplane fires and that you wanted
to feature Soutwest airplanes crashing and burning.

The buildings are actually just additions to an existing building and they
are separated by two adjacent fire walls.

If they are actually separated by fire walls, and not just fire-rated
walls, then they are separate buildings per the IBC. But, yes, you can
use one riser to feed both buildings provided that you protect the
connecting pipe from freezing temperatures and you do not exceed the
maximum allowable
Remove them

Old gripe, but we need to differentiate PRV as a pressure relief valve, from
PRV as a pressure regulating valve, from PRV as a Pressure reducing valve.
All three are different devices with different applications. Some operate on
similar principals, but are not interchangeable.
Just gets
There is a special vinyl material that sign makers use when doing sand blasted
signs but if it's not applied correctly or if the pressure and grit are higher
than what's used for sign making it won't protect the heads.
Best thing to do is what has been suggested and remove the heads. Just

I saw the commercial and I thought it was funny. I don't understand why we get
so upset as an industry when we see these un-realistic depictions of
sprinklers. It's not like all the other comedic stuff we see in advertising or
sitcoms represent reality... besides, it gives us an opening to
Probably because when we talk about sprinklers people will say I don't want
sprinklers because of what they do, you know like in that XYZ commercial.
Convincing them otherwise becomes an uphill battle because despite our best
efforts they already have developed a negative mindset due to their
I agree with Bob. The more sprinklers people see, the more opportunity we
have to talk about 'em. I just wish I'd seen the commercial; I'll be looking

keep in mind the list of variables to consider listed in A.8.2.5. It
is a good question for the consultants and AHJ's to respond to since
there is a difference on how you treat small auxiliary buildings and

As a change of subject, kind of.
Why does NFPA 13 report no minimum air pressure when doing a cold weather 2
hour test. (16.2.1.3, 02 edt)
NFPA 14 states 40 psi for cold weather test. (9-4.1, 00 edt.)
NFPA 25 states 25 psi for test of existing dry standpipes. (6.3, 02 edt)

When we witness dry pipe and or interim air tests we make sure to
schedule them in the morning at the same time of day for the start and
finish of the 24 hr period.

Yes 13 does have a specific pressure.

Paul:
That usually only applies if they are on separate lots or arranged so that
in the future they could be separated and sold as separate properties. These
additions don't appear to meet those concerns. I usually like to look at the
other building services.
Is the electric a separate service?
I guess we'll have to agree to disagree on this because I don't think it
takes a lot of conversation to set people straight when it comes to
technical truths and frankly, most of the people I know don't believe the
satirical themes they see in TV commercials... well, except for the

I have dealt with engineers and project managers over the years who believed
