What type of signal indicates a problem within the fire alarm system?

The trouble alarm signal is specifically designed to indicate that there is a problem within the fire alarm system itself. This type of signal alerts maintenance personnel or monitoring services that the system may not be functioning properly, which could include issues such as power failure, a malfunction in the detection devices, or compromised wiring.

While control signals are typically used for managing the conditions of the fire alarm system, and emergency signals are intended to alert occupants of a fire or danger, the trouble alarm signal uniquely addresses system integrity and readiness. Warning signals can communicate various conditions, but they lack the specific focus on system malfunctions that characterize trouble alarm signals. Understanding the significance of these signals is crucial for ensuring the reliability and effectiveness of fire safety measures.
