Alarm | DHI-HY-GA40A

System Overview

DHI-HY-GA40A Gas Alarm is designed to connuously monitor methane

concentraon. Adopng a catalyc-type gas sensor, advanced electrical

technology, MCU, a built-in high-volume buzzer, it responds quickly

and becomes highly sensive with stable performance and low false

alarm. Once the surrounding methane concentraon reaches the alarm

threshold, it will promptly send out visual and audible alarm signal to

remind the user to take immediate measures. The exhausng fan can be

linked to the relay output port to send out combusble gas. The Device

can also close the pipeline valve to cut o the gas source.
