Which sound pattern is standardized for fire alarm devices?

Explanation:
Temporal-3 is the signal pattern standardized for fire alarm notification. This cadence is defined so that every fire alarm sounds the same across different devices and buildings, making it instantly recognizable as a fire evacuation alert. The repeating three-note pattern is designed to stand out in noisy environments and prompt a quick response. Other patterns like Hi-Lo, Wail, and Chirp are used for different alerts or device statuses, so they don’t serve as the universal fire alarm signal. That’s why Temporal-3 is the standard you’re expected to know.
