The HM-003BHC-DC wired network water leak detector is designed with the alarm output being dry contact signal and optional with N.C. (normally close) mode and N.O. (normally open) mode. The input voltage is DC9-24V. And the alarm indication adopts the red LED. The product outputs the relay signal. Its buzzer would emit the sound larger than 85dB/3m. Meanwhile, the product has the mute function with the mute time reaching up to 10 minutes. This function can avoid that the cleaning work triggers the device to emit the sound to disturb the people at rest. In addition, the wired network water leak detector can connect with the 86×86mm junction box. It is convenient and handy to use.

Product Phenomenon Illustration

Phenomenon	Analysis
The green LED flashes once slowly, and the buzzer sounds for one time.	It shows the battery (>2.4V) is powered on or that the DC power supply is powered on.
The yellow LED flashes three times rapidly, and the buzzer sounds three times as well.	It means that the battery whose voltage is less than 2.4V is powered on.
The green LED keeps light always.	That shows that the DC power source supplies the power normally.
The green LED flashes one time with the interval of about 25s.	It denotes that the battery supplies the power normally.
The red and green LEDs flash one time alternately every 2s.	It is the testing phenomenon showing the testing state which can be stopped just by loosing the button.
The red LED flashes and the buzzer sounds along with the lighting of the LED.	It is the alarm phenomenon in the testing condition. The device can exit from the state just by loosing the key.
The red and green LEDs flash once alternately every 2s, and the buzzer doesnt buzz.	It is the alarm phenomenon showing that the probe detects the existing of water or that the probe contacts the other conductive object.
The green LED flashes once every 2s, and the buzzer doesnt buzz.	It is the alarm mute phenomenon, namely in the state of alarm and mute simultaneously. The mute state can be canceled by long/short press on the HUST/TEST button.
The yellow LED flashes once with the interval of 40s, and the buzzer sounds once with that.	It indicates that the battery voltage is low and less than 2.4V. Please replace the battery timely.
