Does System Require Floor-Level Isolation?

12/17/2018

Have a small five-story restaurant and apartment building (each floor level is only 3,000 sqft), and it's under NFPA 13-2010. Is each floor level of the sprinkler system required to have it's own isolation valve and flow switch?

NFPA 13-10 - 8.16.1.1 - Just says each system shall have a listed indicating valve etc....

However you should check with the local AHJ to verify their requirements, locally we amend that each floor shall have its own floor control valve assembly.

"Note this section was added to the 2013 edition of NFPA 13"

8.16.1.5.1* Multistory buildings exceeding two stories in height
shall be provided with a floor control valve, check valve, main
drain valve, and flow switch for isolation, control, and annunciation of water flow on each floor level.

8.16.1.5.2 The floor control valve, check valve, main drain valve, and flow switch required by 8.16.1.6.3 shall not be required where sprinklers on the top level of a multistory building are supplied by piping on the floor below.

8.16.1.5.3 The floor control valve, check valve, main drain valve, and flow switch required by 8.16.1.6.3 shall not be required where the total area of all floors combined does not exceed the system protection area limitations of 8.2.1

if you have a five story building you probably have a standpipe system. NFPA 14 requires combination systems to have specific requirements, basically a check valve and a floor control valve assembly (all components for a new system) be provided.
