DY-SQ100B Water Leakage Detector with Two Sensors(White) Features 1. Rustproof sensor 2. Low power consumption 3. Low voltage indication 4. MCU control removes various false alarms 5. SMT manufacture technics bring stable performance About The Product 1. Function: When the two sensors detect the water, the red LED indicate light on the detectors will be on and transmit the wireless signal at the same time. The alarm system will transfer the alarm information after receiving the wireless signal. 2. Pair with alarm system: Only after the detector pairs with the alarm system, the alarm host will receive the wireless signal of the detectors. 3. Pairing method: Firstly make the alarm host in the status of adding detectors. Secondly, touch the two sensors on the bottom of the detector by hand. The LED light will be long on. After the host receives the wireless signal from the detectors, it will make a beep or the voice will prompt "adding completed". 4. Low voltage indication: When the LED indicate light flashes, it means it is in the low voltage. 5. The compatible mode of the detector: - When the jumper cap of the detector is in the off state, it is compatible with the common alarm host and doesn't have low voltage indication. - When the jumper cap of the detector is in the closure state, it is not compatible with the common alarm host.
