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.

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.

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.

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.
