  Check: Perform endoscopic examination of main pipe network for internal corrosion, mineral deposits, and rust; assess hydraulic impact and remaining pipe wall thickness; conduct main drain tests to verify control valve operation; inspect all trim valves in correct open/closed positions
• Area: Fire Detection System Integration and Signal Integrity
  Check: For systems with electric or pneumatic release (TraFoProtect with UniVario/FMZ 5000, PVProtect with heat detectors, EconAqua systems): verify all detector signal paths; test short circuit detection in monitoring circuits; confirm automatic activation signal transmission under simulated fire conditions; check for line interruptions or water supply status indicator function

Typ-universelle Inspektionspunkte fuer Fixed Fire Suppression (verifiziert, 2026-06).

• Area: Valve Actuation and System Response Time
  Check: Conduct annual full trip test of deluge valves; record time from detector activation to water discharge through all nozzles; verify compliance with maximum 3-year interval requirement for full trip tests
• Area: Pressure Gauge Calibration and System Pressure Maintenance
  Check: Visually inspect pressure gauges quarterly; verify water pressure at hydraulically remote sprinkler and deluge valve inlet; confirm jockey pump maintains correct pressure (9 bar for ProCon systems, 40-90 bar for ProCon XP)
• Area: Nozzle and Sprinkler Obstruction, Corrosion, and Physical Damage
