Multiple Choice

After 30 seconds of unanswered chime, the door automatically unlocks for how long?

The idea being tested is how a timed unlock works after a chime goes unanswered. When there’s no response for 30 seconds, the system opens the door for a brief window to allow entry, rather than leaving it unlocked longer. Five seconds is the chosen duration because it provides enough time for someone to reach and pass through the door, but is short enough to minimize security risks and unnecessary energy use. Longer windows—ten, fifteen, or twenty seconds—would keep the door open longer and increase the chance of unauthorized entry, while a shorter window might not give a valid user enough time to get through.
