Alarm | DHI-HY-GC20B
System Overview
Standalone Carbon Monoxide Alarm is designed to connuously
monitor Carbon Monoxide concentraon. Adopng advanced electrical
technology, a built-in high-volume buzzer, it responds quickly and
becomes highly sensive with stable performance and low false alarm.
Once the surrounding Carbon Monoxide concentraon reaches the
alarm value, it will promptly send out an audible and visual alarm signal
to remind the user to take immediate measures.
