During ITM, what pressures must be recorded on ITM tags?

• A. When the building is occupied
• B. At the time of inspection, testing, and maintenance service
• C. Only at initial installation
• D. Only after major repairs

Answer: (B)

The pressures must be recorded at the time of the inspection, testing, and maintenance service. Recording the actual pressure readings during that ITM visit creates a current snapshot of the system’s condition, showing exactly what the system is delivering or maintaining at that moment. This is essential because pressures can change with valve positions, leaks, water supply issues, or after repairs, and a tag that only reflects initial installation or post-major repairs would miss these updates. By logging the pressures observed during each ITM event, the tag provides an accurate, up-to-date reference for building owners, inspectors, and authorities to verify ongoing sprinkler reliability.
