1.1 General
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.
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) Ongoing analysis of sensor readings or system conditions to ensure monitoring of system integrity.
(i) Pressure based or other means of micro leak testing for detection of pinhole leaks or dripping fixtures; or,
(j) Provide hardwired or remote access to control a valve (e.g. remotely controlled valves).
Note: Several common terms are used to identify devices covered under this standard a few examples of such terms are Water Leak Detection Device, Automatic Water Leak Detection Device, Leak Detection and Control Device, Adaptive Plumbing System Monitoring and Control Device, and Electronic Plumbing Supply System Integrity and Protection Device.
