Time delays shall not be used as a means of which action?

• A. Confirming operation of a detection device before automatic actuation
• B. For personnel evacuation
• C. For system maintenance
• D. For calibrating sensors

Answer: (A)

Immediate actuation on detection is essential. Using a time delay to confirm that a detection device has operated before releasing the agent would slow down the response to a real fire, giving the fire more time to grow and potentially causing greater damage or risk to occupants. The system is designed so that once detection is triggered, the automatic release follows promptly, with separate warning and evacuation measures handled through alarms or designated test/maintenance procedures rather than delaying actuation. Maintenance and calibration are performed in controlled test modes, not by inserting a delay into the automatic actuation sequence.
