What is an advantage of a dry sprinkler system?

The advantage of a dry sprinkler system primarily lies in its design, which involves the use of pressurized air or nitrogen in the piping system instead of water. This feature significantly reduces the risk of freezing in environments where temperatures can drop below 32°F (0°C). In such climates, wet sprinkler systems can be prone to freezing, which can lead to pipe bursts and system failures.

In contrast, dry sprinkler systems are particularly beneficial for unheated spaces like attics, parking garages, and warehouses, where the risk of pipes freezing is otherwise high. The dry system keeps the water supply separate from the areas exposed to colder temperatures until the system is activated, ensuring that the sprinkler heads remain operational in the event of a fire, while also protecting the integrity of the system from potential cold-weather related damage.

Other options, while they may have their own merits in different contexts, do not directly pertain to the fundamental advantage associated with dry sprinkler systems in relation to temperature sensitivity and climate considerations.
