Water Leak Sensor

User Manual

The water leak sensor is a device that can detect water leaks on both the top and bottom sides, allowing for early intervention and damage reduction. It is designed to be placed in areas where water leaks may occur, such as under sinks, washing machines or in laundry cellars.

product Specifications

• Battery: DC3V, 1 x CR2450 battery required
• Battery life: up to 3 years
• Standby current: N/A
• Alarm current: N/A
• Alarm volume: 110dB
• IP rating: N/A
• Smart Home Integration: N/A

Alarm When water is detected by either pair of detection probes on the top or bottom, the sensor immediately sounds an alarm for 200 seconds. After the initial alarm, it will beep every 30 seconds until the battery runs out.

Usage Instructions

1. Install a CR2450 battery into the device.
2. Place the sensor where water leaks may occur, such as under sinks or near washing machines.
3. If water is detected, the sensor will sound an alarm for 200 seconds.
4. Take immediate action to address the water leak.

Introduction

The water leak sensor can detect leaking water on the top and bottom side, enabling early intervention and damage reduction. Simply place the sensor where water could leak, for example under the sink, the washing machine or in the laundry cellar. As soon as a water leak is detected, it will sound a high- pitched 110dB alarm to alert you to take action immediately.

Using and Installing the Water Leak Sensor

1. Power on
   The sensor requires 1x CR2450 battery, which has been installed, please pull out the insulation strip to us.

2. Test To test the sensor works properly, short-circuit the two probes on top and bottom with a screwdriver or other conductive object to imitate an alarm for a water leak.

3. Place the sensor in the spot where water leak may occur
   Choose a spot where floods, leaks, and water infiltration can occur and ensure that the detection probes touch the surface being monitored. It is Ideal for use in areas not usually observed:

   • Water heaters
   • Behind washing machines or dishwashers
   • Under sinks
   • Sump pumps or inside pits
   • Toilets
   • Behind or near media systems Note: If the surface you’re placing on is not flat, try to place the sensor at the lowest point.

4. Alarm
   When water is detected by either pair of detection probes on the top or bottom, the sensor immediately sounds an alarm for 200s, then beeps every 30s until the battery runs out.

5. Clear the alarm
   Wipe up the water on the sensor with a cloth or tissue and it will stop the alarm.

6. Replacing Battery

1. Remove the three adhesive silicone gaskets from the bottom of the sensor.
2. Using a Phillips screwdriver, remove the three screws.
3. Remove the back cover
4. Remove the old battery and replace with a new battery (verify the polarity and insert properly + and – marked on the battery)
5. Reassemble the sensor and ensure that the silicone gasket is secure to avoid any water infiltration.

Troubleshooting

Pull out the insulation strip before use
Battery runs low| Replace a new battery
Battery installed improperly| Re-install the battery
