A pressure gauge must conform to what section prior to being installed in each system riser?

A pressure gauge must conform to Section 8.17.3 prior to installation in each system riser because this section specifically addresses the requirements and standards for pressure gauges used in fire protection systems. Section 8.17.3 outlines the specifications that pressure gauges must meet to ensure accuracy, reliability, and safety in monitoring the pressure within the system. This includes aspects such as calibration, pressure range, and installation procedures that are critical for maintaining the functionality of the fire protection system.

Knowledge of these details is crucial for sprinkler fitters, as proper installation and functioning of pressure gauges are essential for ensuring that the entire fire suppression system operates effectively during an emergency. By adhering to the standards set in this section, fitters can be confident that the pressure readings are both accurate and reliable, which is vital for system performance and regulatory compliance.
