The Kunlun JS-HP-1/2 water immersion transmitter manual provides specifications, wiring, installation and selection guidance.
The JS-HP-1/2 is a bracket‑type needle probe water‑immersion transmitter that detects water intrusion by monitoring the resistance change of the probe. It integrates the probe and transmitter in one unit and offers isolated power, input and output for reliable operation in environments such as communication base stations, server rooms, libraries, hotels and warehouses.
The manual details the device dimensions, key technical parameters, wiring diagrams for both high/low‑level and relay outputs, installation using four mounting holes, and selection options for different alarm modes. Safety measures include optical, coil and relay isolation. This manual is written in Chinese.
