That is commonly called a "two stage alarm", many campuses or large interconnected buildings have systems that prevent audible alarms for a set amount of time. Someone is sent to check, who can either fully engage the alarm or cancel it before the fire department is called. Very useful in situations where false alarms are unwanted and there is a staff that can do it. Generally after a short time without input they still will engage the alarm.Here at OU we have a really good rapport with the campus "Risk Management" (fire marshal) office. We invite them in for a test, and if needed we have them bypass the audible signal; but it still registers with the office (who then would send out an officer to inspect if there is an active trip during the by-pass). Most of our sensors are heat, not particle though.
This is in part an issue of people coming up with rules who have no concept of the things the rules surround. They should consult with theatre people for specific code rules to conver theatre spaces. As someone whos worked as an electrician who installs fire alarm systems, and delt directly with installers in a venue I can say that they really have NO CONCEPT of what happens on and back stage.
A great example of how local Fire Marshal's have a wide variety of options at their disposal. So the correct answer for anything like this is call your Fire Department and ask.
