What does a trouble signal indicate?

A trouble signal indicates that there is a fault in a monitored circuit or component within the alarm system. This type of signal serves as an alert to the operator that something may be malfunctioning, whether that be wiring issues, sensor failures, or other operational defects that could compromise the integrity of the alarm system. It is crucial to address a trouble signal promptly to ensure that the system remains functional and reliable in the event of an emergency.

While maintenance requirements can arise from trouble signals, the focal point of the signal itself is to indicate the specific issue present in the monitored circuits or components, which is essential for the ongoing safety and effectiveness of emergency communication systems.
