Normal Product Operation

1. The green LED light will stay off during normal operation.
2. When the probes come into contact with water, the Latch Water Sensor will transmit an alarm signal to the Latch Hub and audibly beep with a built-in buzzer.
3. When water is detected, the buzzer goes on for 1.5 seconds and repeats every 20 seconds for 10 minutes. After 10 minutes, the buzzer will go off every 10 minutes for 1.5 seconds for up to 2 hours.
4. When the water level subsides, the Latch Water Sensor will transmit an alarm restore signal and stop the alarm. The Latch Water Sensor then returns to Normal Operation Mode.
