How long can alarm verification delay an alarm from sounding?

The correct answer is 60 seconds because alarm verification is a feature implemented in many smoke detection systems that allows for a delay in the alarm sounding to reduce the likelihood of false positives. This mechanism typically entails monitoring the initial smoke detection event and withholding the alarm for a specified duration, often set to 60 seconds. This time frame gives occupants a chance to investigate the situation and potentially confirm whether the alarm was triggered by a legitimate fire condition or a temporary, harmless issue, such as cooking smoke.

Other options are shorter or longer durations which might not align with standard practices for smoke detector alarm verification protocols. The widely accepted interval of 60 seconds helps ensure safety while minimizing unnecessary evacuations or response actions triggered by false alarms.
