What indicates that there is a fault within the fire alarm system?

A fault within the fire alarm system is typically indicated by trouble alarms. Trouble alarms signal issues that may affect the system's functionality, such as wiring problems, sensor malfunctions, or a loss of power to critical components. These alerts prompt responders to investigate and address any potential issues, ensuring the system operates effectively when needed.

Alarm notification activation, while important, indicates that the system has detected a threat and is functioning correctly in terms of alerting occupants. Control panel alerts can signify a range of issues but are not exclusively indicative of a fault; they can also relate to normal operational states or required maintenance. Smoke detection is focused on the presence of smoke, which activates the alarm system, but it does not necessarily relate to system faults. Thus, trouble alarms are specifically designed to alert users of faults within the fire alarm system.
