The gas alarm controller, in combination with gas detectors, can be used to detect toxic, harmful, and flammable and explosive gases in the air. The gas controller and gas detectors are used in a one-to-many connection mode. This controller can centrally detect multiple gas detectors and has a fast response speed. When the gas concentration in the environment detected by the gas alarm reaches or exceeds the preset alarm value, the controller can promptly issue audible and visual alarms to remind of taking safety measures in time, and control the driving of exhaust fans or other peripheral actions to prevent the occurrence of poisoning, fire, and explosion accidents, thereby ensuring the safety of life and property.

The gas alarm controller instrument can be optionally purchased to achieve  gas detector signal upload or a set of RS485 signal upload to DCS or PLC. It is standardly equipped with on-off output (low alarm and high alarm) control signal output, which can control equipment such as exhaust fans and valves.
