What is the purpose of a trouble alarm in a fire alarm system?

The purpose of a trouble alarm in a fire alarm system is to indicate a system fault. When the system detects conditions that could hinder its ability to function properly, such as a break in wiring, a malfunction in a component, or any other anomaly, a trouble alarm is triggered. This alert notifies maintenance personnel or the monitoring service that there is an issue which needs to be addressed to ensure the reliability and effectiveness of the fire alarm system.

The detection of a fault is crucial because a non-functioning system can lead to a failure to provide alerts during a fire situation, putting lives and property at risk. Consequently, the presence of a trouble alarm is an essential feature that ensures the integrity of the fire protection system by providing early warnings of any potential issues.
