FA Notification requirements for Residential Townhome Sprinkler System

New Townhomes in PA require sprinklers NFPA 13R or 13D.  The contractor installing the sprinkler system is providing a flow switch. The fire marshal want a horn/strobe located in the hallway by the bedrooms tied to the flow switch so it activate when there is flow. Typically this type of install would require a control panel with the proper battery back up.

I see nothing in NFPA codes or the International residential code that this horn/strobe is required. 

It would be simple to install a 120V horn/strobe activated by the flow switch but.....

 

(remembering this is residential);

 

  • Is it Code required to provide the requested horn/strobe?

 

  • If not required by Code and we do install the horn/strobe to satisfy the fire marshal would it need to have battery back up. That would be a problem with the simple 120V horn/strobe wired to the flow switch.

 

  • I am also curious if it is required to Supervise the flow switch (this was not brought up by the fire marshal)

 

Any code references citing a requirement would be helpful if they exist.

 

Thanks for the input.
