What are your goals with the sprinklers? Life safety or property
protection?
Life safety could only be achieved if the fire truck (with operator) was
hooked up when occupied. Which I think is what you said. You'll also want
to make sure there is enough water. And I don't mean a full 30 or 60
minutes over the design area. If you go this far just use some judgment. A
500 gal. pumper probably isn't enough unless it's hooked up to a hydrant. A
3000 gal. tanker is probably good.
Property protection could only be achieved if hooked up 24/7 (or at least a
few seconds before the fire started if you know when that is).
If the truck ain't hooked up I don't see much value in the sprinklers.

"A smart architect.........."
That's pretty funny for a Tuesday morning.
This question is for the AHJ's or anybody that what to chime in.
We have a Haunted House that wants to build under a grandstand of a local
dirt-track. Per the code it needs to be sprinkler protected. Since this area
is subject to freezing; they want to install what I would call a manual
dry-pipe system. The system would have no water supply, just a FDC with a
pumper attached when the "house" is occupied.
If the hydraulics work out, anyone see anything wrong with this scenario?

A smart architect would have known there are limitations on windows and
glazing in rated construction. He should have been asking some questions
before just "drawing up a drawing" and saying "make it so".

It's permitted this way so what's a fellow to do? Tell the
Architect/Engineer, Building Department, Fire Department and owner that they
have to eliminate the doors and horizontal mullions from 80 ft. of glass
wall? And by the way, the next time you want to use a glass wall you have to
check with Tyco?
By the time we find out about the rated glass wall all the permits are
issued and construction has begun. It's probably a little too late to
architecturally redesign the entire lobby area.

The Tyco limitations are because that is what is required to keep the glass
intact, make the sprinkler work properly, and ensure the wall rating. If it
is designed, installed, approved, and accepted incorrectly it is still wrong
regardless of what the AHJ approves. With all due respect Ron, you won't be
okay if something goes wrong and you haven't used the Tyco sprinkler given
that it is available for this specific application and the information in
the thread below including Chris' input.

If the AHJ will approve closely spaced sprinklers you should be okay.
The Tyco window sprinkler has some severe limitations like no horizontal
mullions which translates to no doors.
Just because a sprinkler is UL Listed for an application it doesn't mean
it's the only thing that can be used. We at the office have often discussed
submitting a line of sprinklers to UL for testing and sending along a tanker
truck of water from phoenix for the test. We would then have the only
sprinkler UL Listed with Phoenix water. Following the window sprinkler logic
everyone would have to buy our sprinkler if they did work in Phoenix. (lol)

Subject: Window Sprinklers
Mornin'. I am bidding a project which consists of an educational facility.
Down the center of the building runs an 8' wide corridor. 60' of one of the
corridor walls is glass. The corridor walls are fire rated so I am
installing sprinklers on both sides of the glass at a max. of 6'
spacing.
Tyco makes a sprinkler expressly for this use. I can find nothing in codes
or standards that require me to use this Tyco sprinkler. Does anyone know of
a requirement to use this sprinkler? Why would a contractor choose to use an
$80.00 Tyco sprinkler when a $3.00 SSP will do the same job? This makes me
concerned that there is one sorta like the CC1 and CC2 sprinkler.
Any input will be greatly appreciated.
