System Overview
DHI-HY-GA40A Gas Alarm is designed to connuously monitor methane
concentraon. Adopng a catalyc-type gas sensor, advanced electrical
technology, MCU, a built-in high-volume buzzer, it responds quickly
and becomes highly sensive with stable performance and low false
alarm. Once the surrounding methane concentraon reaches the alarm
threshold, it will promptly send out visual and audible alarm signal to
remind the user to take immediate measures. The exhausng fan can be
linked to the relay output port to send out combusble gas. The Device
can also close the pipeline valve to cut o the gas source.
