How do you configure environmental alarm zones?

The correct choice for configuring environmental alarm zones is to use 24 hour zones. This configuration is essential for monitoring areas that may be vulnerable to conditions such as fire, flood, or extreme temperatures at any time of the day or night. Environmental issues can arise without warning, and by setting up 24 hour zones, the alarm system ensures that any fluctuations or threats detected by environmental sensors will trigger alerts immediately, regardless of the time.

In contrast, configuring zones only during business hours would leave properties exposed to potential risks outside of these hours. Options that mention "as needed" are not reliable for proactive security, as they imply a reactive rather than preventive approach. Lastly, while an 18 hour zone might work for certain applications, it is not as comprehensive as a 24 hour zone, failing to cover all potential occurrences at any time. Therefore, 24 hour zones are the most effective option for environmental alarm configurations.
