The correct type of sprinkler system designed specifically for areas likely to experience freezing temperatures is the dry pipe system. This system is unique because it uses air or nitrogen pressure to keep the pipes empty of water until a fire occurs. When a fire is detected and the heat activates the sprinkler heads, the pressure drop allows the valve to open, releasing water into the piping system. This design prevents water from sitting in the pipes, which eliminates the risk of freezing during cold temperatures, making it ideal for unheated spaces or regions susceptible to freezing.

A wet pipe system, while effective in many environments, holds water in the pipes at all times, which poses a risk of freezing if the temperature drops. Pre-action and deluge systems are more complex and typically used in specific industrial applications or scenarios where additional flood protection is needed, but they are not specifically tailored to prevent freezing like a dry pipe system is. Thus, the dry pipe system is the most suitable choice for areas where freezing is a concern.
