What must occur after a dry pipe system is activated?

After a dry pipe system is activated, draining and resetting the system is essential to ensure its proper functioning and reliability for future incidents. A dry pipe system relies on pressurized air or nitrogen to keep the water at bay, activating only when the system detects a fire condition. Once the system has discharged water, it must be drained to prevent water from remaining in the pipes, which could lead to stagnation or damage within the system. Resetting the system is also necessary to restore it to its ready state for the next incident, ensuring it is operational when needed again.

While other options may seem relevant in certain contexts, they do not address immediate actions required to ensure the dry pipe system is prepared for future use. For example, while ensuring all alarms are functioning may be part of regular maintenance, it does not directly respond to the issue of preparing the dry pipe system itself after activation. Similarly, waiting 24 hours or calling for a fire inspector may involve other protocols and checks but do not replace the need to drain and reset the system as a primary concern after activation.
