What should be done if the building's HVAC system has automatic responses to alarms?

• A. Disable automatic responses to alarms.
• B. Determine how they work and if they are functioning as intended.
• C. Ignore the automatic responses.
• D. Override with manual alarms.

Answer: (B)

Automatic responses from an HVAC system are intended to protect occupants and equipment by taking predefined actions when an alarm occurs. The best approach is to determine how those automatic responses are designed to work and verify they are functioning as intended. Review the design documents and the sequence of operations for the control system and alarm interlocks, then perform appropriate functional checks to confirm that, during an alarm, the automatic actions engage correctly, at the right times, and with proper status indicators. If anything doesn’t behave as specified, document the findings, coordinate with maintenance or a fire protection engineer, and correct and re-test. This focus on understanding and verification keeps the system reliable and safe, rather than disabling, ignoring, or bypassing automation.
