Preventing false alarms: what action is required to signal an alarm?

• A. Single action
• B. Double action
• C. Verbal command
• D. Hold for 5 seconds

Answer: (B)

To signal an alarm in a way that reduces false alarms, a two-step, or two-action, process is required. This means you must perform two deliberate actions in sequence to activate the alarm rather than a single quick press. The extra step helps confirm that the trigger is intentional and not caused by a bump, accidental touch, or fleeting moment of hesitation. By requiring two actions, the system protects against nuisance alarms while still allowing a clear, deliberate signal when there’s a real need.

Single-action signaling is too easy to trigger accidentally. Verbal commands aren’t reliable on many systems because speech recognition can fail or be misheard in noisy environments. Holding for a duration can be cumbersome and may still be triggered inadvertently. The two-step approach is the standard method to ensure intent and accuracy when signaling an alarm.
