What is the required time frame to initiate and restore an alarm signal?

• A. 90 seconds
• B. 60 seconds
• C. 120 seconds
• D. 30 seconds

Answer: (A)

Timing here is about balancing rapid protection with practical system behavior. The required window for both starting the alarm signal and returning the system to normal after the condition ends is about a minute and a half. This keeps occupants alerted quickly enough to respond, while also ensuring the system isn’t left in an alarm state longer than necessary once the issue is resolved. If the interval were much shorter, false activations could become a bigger problem; if it were much longer, occupants would be exposed to the alarm for too long and the system wouldn’t reset promptly for future events.
