Water Leak Sensor
User Manual
1. Product Introduction
Using the LEEDARSON Water Leak Sensor and the LEEDARSON Application for your mobile device,
you can receive immediate alerts if a leak or flooding occurs in your home (such as in a basement,
near a water heater, under an old pipe, or in a bathroom). Early alerts can help you prevent leaks
from turning into flood situation, extensive property damage and excessive bills.

3. Features/Capabilities
The LEEDARSON Water Leak Sensor is a Zigbee compatible sensor.
The LEEDARSON Water Leak Sensor is powered by AAA battery with a 5-years battery life.
The LEEDARSON Water Leak “alarm” can be sent to Zigbee network devices or to any
compatible alarm system hub.
The LEEDARSON Water Leak Sensor is designed to be a floor type sensor..
The LEEDARSON Water Leak Sensor has a built-in LED indicator and an acoustic alarm.
The LEEDARSON Water Leak Sensor has a low battery alarm to Zigbee
Gateway/Hub devices
4. Installation Notice
1. Install the detector in areas where there is a concern about possible water leaks, such as
bathrooms, basements, water heaters, under clogged drains, under old pipes, or in other areas of
your home that are prone to leaking. You can receive an instant alert.
2. Do not locate the detector in cabinets and other areas where the alarm sound cannot be heard.
3. Do not install in an area where it can come in contact with rain, oil smoke and steam from a
kitchen range.
4. Do not install the detector in submersed water.
5. If a pool of water forms, moisture must contact both leads to trigger an alert.

6. Installation Guide
1. The sensor will be in pairing status when power turns on for the first time. This will cause an
LED indicator light to flash once per second for 3 minutes. Use the LEEDARSON Application to
search for this device. If sensor pairs successfully, the light will stop blinking and then stay on for
about 10 seconds.
2. Install the detector where there is a concern for a potential water leak.
7. Product usage
1. Insert 2 pcs AAA battery to the battery space, and the water leak sensor will be ready for use.
2. How to reset a water leak sensor
A. Press and hold the reset key on the bottom cover for about 3 seconds, then the LED
(signal light) will start blinking quickly.
B. Release the reset key and the sensor will be reset to factory settings and the LED(signal
light) blinks once per second to search for a new enabled Zigbee network.
3. How to pair a water leak sensor
A. After the sensor reset to factory settings, the LED(signal light) blinks once per second and
sensor starts searching an enabled Zigbee network.
B. If sensor pairs successfully, it will stop blinking and the light will stay on for 10 seconds
C. If no available networks were found within 3 minutes, the LED will stop blinking and turn
off.
Tip: When initially setting up the LEEDARSON Water Leak Sensor, it is recommended to perform the
setup task within 15 feet (4.5 meters) of the Zigbee Hub.

4. Once the sensor detects a water leak, the LED Indicator flashes and the alarm beeps once per
second. The alarm signal will be sent to the gateway once every 5 minutes. During the alarm status,
the user can mute the buzzer by using the App. If the sensor still detects a water leak after 10 minutes,
the detector will trigger the alarm again and another signal will be sent to the gateway and the user.
The alarm will be canceled if the situation as below.
① Water leak is controlled/stopped
② User presses the mute status by using the app
③ The button on the sensor itself is pressed
④ Power is turned off
Details about the alarm: there are four settings to select from in App.
⑤ 0: Buzzer muted, LED off
⑥ 1: Buzzer muted, LED flashes
⑦ 2: Buzzer on, LED off
⑧ 3: Buzzer on, LED flashes (Default setting)
6. When the battery voltage low, the detector will send a low battery signal to the gateway.
8. Notes
1. Replace the battery immediately when the low battery warning sounds to ensure the detector is
working properly.
2. Do not store any items on the surface of detector, as this may affect the sensors.
3. Clean the surface with soft towel regularly.
4. In the unlikelihood of a product failure, do not attempt to repair. Please contact the local
distributor.
