Product Introduction
This wireless water leak detector utilizes advanced wireless transmission technology.
When the water level exceeds the preset threshold — that is, when water at the bottom of the
detector covers two or more adjacent water-sensitive probes, or when water at the top
completely covers two water-sensitive probes — the detector will trigger an alarm and send a
wireless signal to the corresponding receiver.
This alerts you to high water levels or water droplets on the detector, prompting you to take
immediate action.

Operation Instructions
Power On
⚫ Install 2 AAA batteries. The red LED will flash once to confirm power-on.
⚫ Press and hold the [Test] button for 10 seconds, a short beep indicates successful power-on.
Power Off
⚫ Press and hold the [Test] button for 10 seconds:
At 3 seconds: volume level changes.
At 10 seconds: a long beep confirms power-off.
⚫ You may also power off the unit by removing the batteries.
Volume Setting
When the water leak alarm is powered on, press and hold the [Test] button for 3 seconds to set
the volume to Level 4 (beep-beep-beep-beep – maximum volume). Release and hold again for 3
seconds to cycle to Level 3 (beep-beep-beep), then Level 2 (beep-beep), Level 1 (beep – mute),
and back to 4–3–2–1.Each 3 - second press adjusts one volume level only.
Note: Removing the battery and reconnecting power will reset the volume to the maximum level.
Test Function
Press and hold [Test] for 1 second. The water leak detector will alarm for 2 seconds and transmit
a wireless signal to the receiving host.
Installation & Placement
Place the detector in areas requiring water leakage monitoring.
Notes:
1. The detector has four water‑sensitive probes on the bottom
⚫ Alarm activates when water touches two parallel probes.
⚫ Alarm does not activate if only the two diagonal probes detect water.
2. Alarm behavior:
⚫ First alarm: 15-second continuous tone.
⚫ If water remains: 2-second beep every 15 seconds.
⚫ Alarm stops when water is removed or the alarm is cancelled manually.
⚫ Alarm automatically disables after 24 consecutive hours of water detection.

External Water Leak Extension Cable 外接延长线
Align the water leak extension cable with the jack and plug it in. （将水浸延长线对准插孔插入）
If water touches the extension cable sensor, the water leak detector will alarm at once
Low Battery Indication
When the voltage drops below a specified level, the water leak detector will emit three short
beeps and send a low-battery signal to the receiver once only.The detector will continue to
operate normally. It will still alarm and send an over-limit water signal to the corresponding
receiver when a water leak is detected. Please take appropriate action promptly.
When the voltage becomes critically low, the indicator light will stop flashing and the unit will
shut down automatically. Please replace the batteries.
