What does it indicate when the trouble buzzer rings on a supervised fire alarm system?

In a supervised fire alarm system, the trouble buzzer serves as an important alert mechanism that indicates issues needing attention. When the trouble buzzer rings, it often signifies a problem related to the system’s integrity or functionality, rather than an immediate emergency situation, such as a fire or alarm being triggered.

Specifically, the correct interpretation is that a wire may have come loose or there could be low pressure in sprinklers. This could indicate a fault in the wiring or challenges with the configuration of the system, such as failing connections or inadequate operation of components like sprinklers that are crucial for fire suppression.

This need for maintenance or attention ensures that the overall system remains operational and can function correctly in case of an actual emergency. Addressing issues indicated by the trouble buzzer is vital to ensure safety and compliance with fire safety regulations.
