Water sensor index:

● Material: fine copper,twin cable 2×1/0.4
● Max switch power:10W
● Working temperature-20–+80℃(higher temperature optional)

Produc Installment:

● Code preset by factory. If not, please follow the following code diagram to play it by clamp; Zone Code Jumper: A0―A7 is address code correspond with alarm host.D0―D3 is data code for setting different zone.  Note: H=1, L=2, Empty =0
● Fix the transmitter part higher than the water sensor rod, water sensor is mounted by screw or sticker paper the wall or place where need to protect water leakage.(installing way refer to above picture)
● It means OK if the Signal LED flashes for 1 second after installation.
● The signal red LED flash for 1 second to alarm, the low battery green LED lights all along which means batter power is not enough. Please replace the same size new battery
● Antenna is suggested to pull out.
