Firewalls
Firewalls
(OP)
Does anyone know of a current NFPA/IBC requirement to provide separate sprinkler and/or fire alarm systems on each side of a firewall (when the IBC requires both systems)?
I have an I-1, Type V-A structure that will have multiple firewalls because of IBC area limitations. I've had some AHJs require separate systems (lead-in, risers, FACU, FDC) for each area...so that no part of the overall structure/building is unprotected during a fire event in any of the other areas. I've also had AHJs allow pipe and cable to pass through the firewalls to serve areas on both sides of the firewalls. So I'm looking for code language in either direction.

I would have a discussion with the AHJ about the issue and see what they require in their jurisdiction.

As to the building classification as a Group I-1, a fire alarm system is not required by the IBC when the building is protected by a NFPA 13 automatic sprinkler system.
