JH-FII Flammable Gas Alarm Controller

I. Product Overview

The JH-FII type combustible gas alarm controller is used in places involving the production, transportation, storage, and filling of combustible gases. It collects the concentration of combustible gases in the air detected by point-type combustible gas detectors (4~20mA signals). When the set alarm value is reached, it outputs corresponding alarm and control signals to prompt on-site personnel to take timely safety measures. It can be connected to systems such as DCS and fire alarm graphics, and can also activate external devices like exhaust fans and solenoid valves to ensure personnel and equipment safety and prevent accidents caused by the leakage of combustible gases.

Controllers are suitable for non-explosive areas such as fire control rooms and control centers.
