ANSI CAN IAPMO Z1349:2021 pdf free download - Devices for Detection, Monitoring or Control of Plumbing Systems 1.1.1  This standard covers devices for detection, monitoring or control of water supply and distribution systems in sizes DN 8 to DN 300 (NPS‐1/4 to NPS‐12) for commercial and residential applications and specifies requirements for materials, performance testing, environmental limitations, installation, and markings.  1.1.2  Devices for detection, monitoring or control of plumbing systems, hereinafter referred to as “devices”, covered by this standard govern plumbing systems through features such as: (a) Automatic shut‐off or electronic alarm notification or isolation of the supply piping when conditions are detected indicating a leak or equipment malfunction (e.g. automatic water leak detection and control device). (b) Detecting the presence of water external to the piping system. (c) Establishing normal water flow patterns and monitoring for anomalies. (d) Monitoring of the hydraulic conditions (e.g. water pressure, temperature, or flow) within the main or branch circuit. (e) Monitoring of the local environment that may indicate potential for freeze conditions; or (f) Monitoring of the local environment for moisture that may indicate a leak (e.g. Physical Water/Moisture Detection Devices). (g) Monitoring of environmental conditions. (h)...
