Answer:

The NFPA 72 standard specifies different sound patterns for fire alarm signals. The temporal 3 sound pattern is one of the options defined by this standard.

Step-by-step explanation:

The temporal 3 sound pattern consists of three audible signals followed by a pause, repeating in a cyclical manner. Each audible signal lasts for a specific duration, typically 0.5 seconds, followed by a pause of the same duration.

The pattern can be represented as follows:

Signal (0.5 seconds) - Pause (0.5 seconds) - Signal (0.5 seconds) - Pause (0.5 seconds) - Signal (0.5 seconds) - Pause (0.5 seconds) - ...

This pattern is used to alert individuals in the area about a fire or emergency situation. The repeated signals and pauses help to attract attention and provide clear distinction from other types of sounds or alarms.

It's important to note that specific sound patterns may vary depending on local regulations and building codes, so it's always a good idea to consult the applicable standards and guidelines in your area.
