Common failures & inspection points

Nozzle and spray head obstruction/clogging from water impurities or mineral deposits

Monthly visual inspection for visible blockages; annual cleaning and flushing of nozzles through strainer validation. Check strainer condition (typically 300 µm micron filters). Water quality testing per EN 14972 standards.

System pressure loss or inadequate discharge pressure (target: ~1,050 psi sprinkler, 2,300 psi discharge)

Quarterly pressure testing via pressure gauges. Verify pump discharge pressure (2,300 psi target). Check accumulator pre-charge pressure (nitrogen/compressed air). Validate integrity of high-pressure tubing for micro-cracks or corrosion.

Heat-sensitive bulb degradation, glass micro-cracks, or bulb failure in sprinklers (57°C to 141°C ratings)

Annual visual inspection of bulbs in sample sprinklers from each temperature rating. Replace bulbs showing discoloration, cloudiness, or micro-cracks. Validate bulb response through functional testing per EN 14972. Thermographic scanning of ceiling areas.

Water supply contamination, corrosion of stainless steel components (AISI 316L), or scale buildup in piping

Annual water quality analysis (potable water standard per EN 14972). Visual inspection of interior tubing sections for corrosion via test ports. Flush system at min. 5-year intervals. Inspect stainless steel tubing for surface oxidation or pitting.

Control system, PLC logic, or activation mechanism failure in LPU/EPU/GPU units

Annual functional system activation test (dry discharge test) to verify pump start, pressure rise, and valve actuation. Battery backup verification. Software/firmware version check on PLC controllers. Validate touch-screen interface display on LPU. Simulate fire signal activation.
