Sprinklered buildings are required to have at least 1 pull station.
This pull station is typically near the riser room. It’s purpose is so the sprinkler guy can activate the alarm if needed (while his system is down).
Why would his station be done? Don’t sprinklers activate when the glass breaks or the soldier melts due to the extreme heat?

testing, maintenance, expansion… sprinkler system is off, pull station is needed to activate fire alarm by the sprinkler guy if something happens.
Oh yeah. You know what? Now that you think of it, that does make sense. Nevermind.
Where I live, unless your building is one large open room such as a grocery store, you are required to have smoke detectors throughout along with sprinklers. Grocery stores will have smoke detectors in any back room that can’t be seen at all times or in bathrooms. If the building is fully outfitted with smoke detectors and sprinklers, all but one pull station is allowed to be eliminated. That one pull station however is required to be accessible to the public, normally it is installed in a vestibule by the main entrance. This one pull station essentially gives one approved door that is in a public space a manual alarm box. As far as alarms are concerned, all spaces are required to be outfitted with voice EVAC as of modern code. The rules about public and private areas having strobe differences in placement had also been scratched. All strobes are required to be placed in every part of the building with no blind spots and each device must illuminate the space of at least 75 candelas too which is a new thing. Audio clarity is also required which means more remote speakers are needed.
