Product Features
- High Sensitivity Leak & Drip Water Detections: Equipped with 4 bottom and 2 top high-sensitivity sensor probes. The adjacent bottom probes trigger the alarm upon contact with water, while the top probes can be activated by heavy humid mist. This design precisely detects dripping water, minor water pooling, and flooding on various flat surfaces.

- 0-120dB Adjustable Volume & Silent Mode: Offers 4 adjustable volume levels, from a silent mute mode up to a 120dB super loud alarm. The volume can be adjusted by long-pressing the TEST button. The alarm can be muted after a leak is detected.
- IP66 Full Waterproof & Dustproof: Constructed to withstand harsh conditions, this detector is fully waterproof (IP66-rated) and dust-resistant. Its durable structure and rust-resistant coating ensure long-term reliability.
- Easy Place Installation: Requires no complicated wiring or extra tools. Simply place the alarm in leak-prone areas for 24-hour automatic monitoring.

Maintenance
To ensure reliable operation and prevent false alarms, especially in highly humid environments, it is important to perform regular maintenance:
- Sensor Probe Cleaning: This detector senses water via electrode conduction. In highly humid environments, water mist can cause false triggers. Regularly wipe the sensor probes to keep them dry and clean.
- Battery Replacement: When the low battery reminder (red flashing light) activates, replace the AAA batteries promptly to ensure continuous leak monitoring.
Troubleshooting
- Alarm Not Sounding:
- Check if the batteries are correctly installed and not depleted. Replace if necessary.
- Ensure the sensor probes are making proper contact with the surface where water might accumulate.
- Verify that the volume is not set to mute (0dB). Long press the TEST button to adjust volume.
- False Alarms:
- Wipe the sensor probes dry. High humidity or condensation can sometimes trigger the alarm.
- Relocate the detector if it is consistently exposed to high humidity without actual water leaks.
- Low Battery Indicator Flashing:
- Replace the AAA batteries immediately to maintain continuous protection.
