Purpose and function
The leak guard can monitor the possible water leakage from dishwashers, hot water heaters or any other
machine or equipment. When properly installed, the leak guard will report water leakage before it can be
detected by other means.
When water or moisture appears between correctly installed sensor wires, a small current starts to flow between
the wires. The leak guard detects the current and triggers an alarm. The leak guard light starts flashing and the
indicator light / buzzer / beeper is triggered. The alarm can be silenced with the silencer button on the unit.
However, the light of the leak guard remains on without blinking until there is no more moisture between the
sensor wires.
The leak guard has two function selectors, “M” and “R”, which can be used to adjust the unit's functioning.
The leak guard controls the leakage current passing through the sensor. Increasing the number of sensors
increases the leakage current rate, making the alarms more responsive.
