Not sure I understand your question. Are you asking what the difference is between a security system with smoke detectors and a fire system?

I'm not a fire system guy but I can give you what I understand. Basically the difference is reliability and durability but there is also initiating and notification devices that are unavailable with a simple security system. Yes, a fire system can be set up to report what zone is in alarm as well as operate annunciators for the first responders. A fire system will have supervision of all wiring and devices. Depending on the size and occupancy of a building code will dictate what type of fire system will need to be installed.
