A Temporal X signal is used to signal total evacuation. What number should X be?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (C)

When signaling a total evacuation, the alarm uses a specific Temporal pattern that is unmistakable and meant to prompt immediate egress. Among the Temporal cadences, the one reserved for full evacuation is the pattern most people are trained to recognize as “evacuate now.” That is the Temporal three pattern. So X should be set to that pattern. Other Temporal cadences are used for warning, alert, or all-clear conditions and do not convey the immediate, all-out evacuation instruction, which is why they aren’t the correct choice.
