The HT type alarm control host is used with the alarm detector, which can receive the signal of the gas detector detector, and when the measured value reaches the set alarm value, the control host emits sound and light alarms, and outputs the control signal (switching contact output) at the same time, prompting the operator to take safety treatment measures in time, or automatically start the pre-connected control equipment to ensure safe production. AT series alarm host is suitable for all kinds of industrial alarm control, wall-mounted installation, simple installation, easy operation, stable working state, high measurement accuracy.
