True or False: Dry pipe systems may be gridded.

Dry pipe systems are designed to contain air or nitrogen under pressure, which holds a valve closed until the system is activated by a sprinkler head. These systems are typically used in environments where it is unfeasible to have water in the pipes due to the risk of freezing. Gridded systems, on the other hand, allow for the distribution of water through multiple paths, which can create potential issues with water supply and drainage, especially in dry pipe configurations where maintaining pressure and preventing condensation is critical.

In general, the nature of dry pipe systems limits their configuration as gridded systems because the design and operation principles of dry pipe systems do not align well with the complexities introduced by gridding. The advantages of a more straightforward layout typically seen in dry pipe systems outweigh any potential benefits that might be gained from a gridded approach. Thus, the statement that dry pipe systems may be gridded is false, as it contradicts standard practices and design considerations in fire protection systems.
