I have been requested to Install window sprinklers in a house due to the proximity to the adjacent building. Is it acceptable to use QR Pendants or Uprights in lieu of listed window sprinklers?
A single family house???
How many windows do you have to protect??
Yes normally you need a listed window sprinkler.
What hourly rating to you have to provide?
Cheaper in the long run to get rated glass??
Yes, a single family house. 2 windows on the main level and 1 on the 2nd level. From my understanding, pendants and uprights have been approved in certain cases. I have only ever installed the Tyco listed WS and they’re rather $$.
More than likely a question to the local ahj, to see what they will accept.
I take this is a southern/ or western state.
Do you do it off the domestic?? Or does the house have a fie sprinkler system.
do you want to say which state or city this is in?
In Atlantic Canada actually! It’s coming off of the domestic. It’s a complete renovation of an old 100+yr house. I have had a similar circumstance in our neighbouring province in which the building inspector wanted a 13D system. I’d say that would be the way to go. Especially if they’re looking for something aesthetically pleasing.
A little to far north.
So no allowances for historical building??
How do you keep the pipe from freezing??
In this case, we are only looking at interior protection. So, no freezing. There are some buildings here in town that have exterior protection (exposure). Those are all run off of a Dry Pipe Valve.
No allowances for historical building. The house has been gutted and is being re finished, so that’s where the building inspector came in with the window protection.
Interesting set up
I am thinking the question is up to the ahj which sprinkler they will accept.
Still think pay the money and get rated opening,
I’ll send them an email. Thanks!
Plus I thought you are trying to protect the house with the opening to close to another,
And not sure how a sprinkler on the inside of the house does this????
By the time the fire from the other exposure attacks the house, and gets through the opening, and activates the sprinkler, I am thinking there will be a lot of damage.
I would have to agree with that statement. This was at the request of the building inspector and I am waiting for more information from him. Perhaps, they require this to keep the windows from shattering and potentially harming someone inside the house(I wouldn’t be inside if my neighbours house was on fire) or to keep the flames from spreading inside the house? Yes, it was requested because of the proximatey to the neighbouring house. When I have more information, I’ll be sure to let you know exactly what their rationale was for requesting this type of protection!
Good luck, sounds like you need it.
Sounds like they may accept any sprinkler???
No idea yet. I had another situation just like this in Halifax. That time, they requested to have a 13D system installed.
