SPD-780B is designed to work together with the locating leakage sensing cable. Once sensing cable find a leakage, it will send a signal to SPD-780B, then SPD-780B will make the relay working and trigger the alarm, and system will pinpoint the leakage location.
SPD-780B can be used as a stand-alone leak detection alarm, or connected to a host system (computer, or control automation system) via MODBUS-RTU(ASCII), pairing RS-485 serial communication wiring.
