Req'ment for Waterflow Notification on Building?

5/30/2019

I've looked for it but I'm having a tough time coming up with the code section. Where does the requirement for a bell on the face of the building come from?

I don't believe this requirement is mentioned in any NFPA. IBC 903.4.2 has a requirement for an audible device connected to the sprinkler system on the exterior of the building.

Agreed. The only requirement is that it’s audible. It’s usually a bell, but can be a horn.

It is indeed mentioned in NFPA 13, section 8.17.1 (2016):

"8.17.1 A local waterflow alarm shall be provided on every sprinkler system having more than 20 sprinklers."

As mentioned bu Bill above, this could be a water motor gong, an electric bell, or a fire alarm horn.

In general that information are in section 6.8 NFPA 13 Ed.2016

Check the section 6.8.3 in the annex mention this:

"Audible alarms are normally located on the outside of the building. Listed electric gongs, bells, horns, or sirens inside the building, or a combination of such used inside and outside, are sometimes advisable"
