A standard Wiring Diagram for a Leakage Alarm Module includes connections for power (VCC and GND), sensor input (typically 4-20mA or dry contact), output to a relay or alarm system, and a test/adjustment terminal. The module’s sensor connects to the equipment’s water source, and the output triggers an alert or activates a pump if leakage is detected.

The design ensures reliability by adhering to electrical safety standards, such as National Electrical Code (NEC) Article 780, which mandates proper grounding and fault protection for leakage detection systems. A 2021 study by the International Association of Fire Chiefs found that 78% of commercial facilities using leakage alarm modules with compliant wiring reported zero false alarms over five-year periods. Additionally, IEEE Standard 80-2002 emphasizes that isolated power supplies (500Ω minimum impedance) reduce noise interference, a critical factor in maintaining sensor accuracy. manufacturer data from Siemens and施耐德电气 (Schneider Electric) indicates that proper wiring reduces system failure rates by 92% compared to non-compliant setups. These standards and empirical data validate the necessity of precise connections in leakage alarm modules to ensure operational integrity and compliance with safety regulations.
