Are they going to store all of the haunted house stuff in there
during the off season? If so, then you have a storage occupancy,
which would provide an exposure to a grandstand, especially when
occupied. Doesn't sound like a good idea. Does Nebraska law allow
sprinkler systems with no permanent water supply? Try NFPA 13 (2002)
section 15.1.1.

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.
