Which statement best describes the role of alarms and indicators in NFPA 2001 systems?

• A. They provide status information
• B. They provide status information, warn occupants, and confirm activation and performance
• C. They monitor room temperature only
• D. They are optional and not used

Answer: (B)

Alarms and indicators in NFPA 2001 systems are all about communication of the system’s status and safety actions. They provide real-time status information so occupants and responders know what state the system is in (normal, pre-discharge, discharge, fault or supervision). They actively warn occupants with audible and visual signals to evacuate or take safety precautions. And they confirm activation and performance by indicating that the agent has discharged and that the system operated correctly, allowing for verification and maintenance as needed. This combination ensures timely safety actions and reliable verification of the system’s operation, rather than just passively monitoring conditions like room temperature or being optional.
