Product Description
The water flow indicator of the ZSJZ series is an auxiliary control unit of automatic sprinkler systems, mounted on the main water supply or branch pipelines of the complex. When a flow of water appears in the main line, the device detects a hydraulic signal, converts it into an electrical signal and transmits it to the fire electrical panel, accurately determining the fire zone, while simultaneously triggering the automatic switching on/off of fire pumps for integrated operation of the system.
Our line is divided into two groups: basic models without delay chain with seven nominal diameters DN50, DN65, DN80, DN100, DN125, DN150, DN200 for pipes of different sizes; models with a time delay circuit with a factory-set pause of 4 seconds, the duration of the delay is adjusted to the requirements of the project, which prevents false alarms due to fluctuations in water pressure in the pipeline. Three installation options are provided: pipe thread, flange connection, saddle mount, suitable for any installation conditions on site. Robust design, easy installation, high sensitivity, compatible with all wet and dry automatic sprinkler systems.
