Actuation of alarm notification appliances shall occur within ______ seconds after the actuation of an initiating device?

Actuation of alarm notification appliances shall occur within ______ seconds after the actuation of an initiating device?

• A. 30 seconds
• B. 60 seconds
• C. 90 seconds
• D. 10 seconds

Answer: (D)

The idea is to warn occupants as quickly as possible after an initiating device is actuated. When a detector or manual pull station is activated, the system should drive the notification appliances promptly, so people hear or see the alarm without delay. Ten seconds is the maximum time allowed for that actuation to occur, keeping the sequence fast and coordinated for a rapid evacuation. Longer delays, like thirty, sixty, or ninety seconds, would slow down warning and undermine safety by giving occupants less time to react.
