A gunshot detection system detects shooting events within a premises and interacts with building management systems installed within the same premises to guide occupants to safety and/or obstruct or trap an active shooter. Gunshot sensor units detect the gunshots and generate event information based on the detected gunshots. A shooting event response module generates and sends building management instructions to the building management systems. In response, distributed devices of the building management systems perform effect changes within the premises according to the functionality of the distributed devices (e.g. locking/unlocking doors, turning off lights, flashing strobe lights). A control panel of the gunshot detection system presents a graphical user interface for presenting response options and receiving selections of response actions to be performed by the building management systems. The shooting even response module also receives gunshot and building management event data and generates recommendation information based on the event data.
