What alarm usually follows a PIR?

Explanation:
PIRs detect movement and signal a potential intrusion. The typical follow-up alarm is a perimeter/BMS alert because the event is treated as an intrusion at the building’s edge and is routed through the security perimeter and Building Management System to log, verify, and coordinate a response. Fire alarms are for smoke or heat conditions and are not triggered by motion signals. CCTV alerts may occur to verify what’s happening, but they’re generally used for verification rather than serving as the standard follow-up alarm. A system fault represents a malfunction, not a normal consequence of motion detection.
