In Contrast to other extra complicated forms of fire suppression methods, less upkeep is required to maintain the system working correctly. NFPA 72 requires that air stress be monitored in order to detect a change of 10 psi below regular air stress. This includes frequently inspecting the system for any adjustments or deterioration, testing water strain ranges, and guaranteeing that entry points remain clear of debris or other obstructions.
