Extension alarm panel and suction pipe channels. Except sending out the alarm when concentration of
Detected gas reaches or exceeds the pre-set value, RDQJ-2 Suction Gas Detection System also designs
With the monitoring and alarm functions for equipment itself such as the power failure and fault of
Detection lines. At the same time, system also monitors the gas concentration inside the Detection
Cabinet itself. The system will override the sample point and stop the detecting of this point as soon as
This sample point found the fault and alarm. All alarms occurred will be saved for further reference.
