2 Channel modular gas detection controller
Through the connection of 2 remote sensors, the BX280 control unit has been designed and built according to European regulations to detect the presence of toxic and/or explosive gas flexibly.
A microprocessor is used to create a complete surveillance and control system with maximum flexibility. Thanks to this and its other features, the BX280 is suitable for civil and industrial applications.
The BX280 control unit has two hazard levels:
1st LEVEL, 1st Pre-Alarm. is set at 13 % of L.E.L. for all sensors.
2nd LEVEL, Main Alarm. is set at 20% of L.E.L.
