A dry pipe system is characterized by being filled with air or nitrogen under pressure, rather than water. The system holds water in a remote storage, and the piping remains dry until a fire is detected. When a sprinkler head opens due to high temperatures from a fire, the pressurized air is released, allowing the water to flow from the storage into the pipes and out through the opened sprinkler heads. This design is particularly useful in environments where freezing temperatures could be an issue, as it prevents water from sitting in the pipes and freezing.

This operation contrasts with systems that maintain water in the pipes at all times, which can lead to complications in cold environments. Additionally, while rapid response mechanisms and foam systems are features of other fire suppression systems, they do not define the dry pipe system specifically. The unique aspect of the dry pipe system is how it uses stored water activated by the release of pressurized air, making it effective for specific deployment scenarios where pipe freezing is a concern.
