Understood and agree.
My point is that testing and engineering can be used as a tool but do not throw
out the baby with the bath water. Some of the old guys that wrote NFPA 13 were
quite good.
I forgot Polybuthlene and PozLock piping which were listed and tested etc. but
were removed from
Saw this once at the NY Air National hanger for C5A's. It could hold 2 at a
time. A Guardsman smelled smoke and called control. They told him pull the
alarm. Well, the manual dump for the foam was blue and the fire alarm was
red. They were right next to each other. He pulled the wrong one.
Bill,
How important is this? Until yesterday we were only concerned that the
system tripped (which in reality would have left the IT anywhere since
the air decompresses evenly) and that there was no debris in the
system which would work its way to the opening. Oh and that water

the test six big brass and the base commander wanted to see it happen.

assumption in 13 was that a 500 gal system (or 750 with an accelerator)
would meet that requirement. Turned out to be a bad assumption.

If you are interested I have a document that I call Rules of Thumb for
designing large dry systems that might be helpful. Not engineering but
just old time rules that I learned at Automatic many years ago. If
you will send me your email address at [EMAIL PROTECTED] I
will be happy to share
I am looking to make contact with a sprinkler system designer James Larkin.

Hello Russell,
I had a CoE guy insist the Abort on a HUGH Co2 system would abort a manual Pull
Station. Lucky there was a 55 gallon drum under the overhead door for us to get
out of when that 10' diameter x 30' long Co2 Tank dumped. My truck was about
