5 breezeway sprinklers

5 breezeway sprinklers

5 breezeway sprinklers

(OP)
I have a 13R design apartment building with an open unconditioned breezeway that is open from the front of the building to the back of the building. Are the 5 most remote dry sprinklers still to be calculated or can it be 4 most demanding for a light hazard area? The breezeway is less than 75' and I have a mixture of extended and standard coverage dry sprinklers.

RE: 5 breezeway sprinklers

13R states to refer to NFPA 13 for calculation criteria for areas outside of the dwelling unit. So, if you are using spray sprinklers and not residential sprinklers, I would go with the 5 sprinkler calculation. If you are using residential sprinklers outside of the dwelling unit, then you can use 4 sprinklers.

That is just my opinion. I tend to go overly conservative at times.
