What is an indicator of malicious false alarms within a building?

Continuous activation of manual pull stations serves as a strong indicator of malicious false alarms within a building. This behavior suggests a deliberate act, as it involves repeatedly triggering the alarm system without an actual fire or emergency situation occurring. Such actions often stem from a desire to create a disturbance, cause panic, or test the system for vulnerabilities.

On the other hand, timed false alarms could result from various factors, including system malfunctions or environmental influences, lacking the intent behind malicious behavior. Smoke detector inactivity may indicate issues with the detectors themselves, but does not imply intentional wrongdoing. The presence of flammable materials, while concerning for potential fire risks, does not directly relate to the act of triggering alarms falsely. Thus, continuous activation of manual pull stations stands out as a clear marker of intentional disruption in the context of fire safety.
