What section of the NFPA 72 would require initiating devices to activate indicating devices upon a "fire" alarm activation?

My inquiry is on deluge system activation, pressure switches. Does NFPA 72 specify that horns and beacons shall activate upon activation of any initiating device? (I consider a pressure switch on deluge system is an initiating device)

 

I'm aware that activation of indicating devices would vary on different applications and system design intents. This information I intend to find would be a supplemental document.
