Through the connection of 8 remote sensors, the BX880-AX control panel, ATEX certified, has been designed and built according to European regulations to detect the presence of toxic and/or explosive gas in a flexible way

A microprocessor is used to create a complete surveillance and control system with maximum flexibility.

Thanks to this and its other features, the BX880-AX is suitable for civil and industrial applications.

The BX880-AX control unit has two hazard levels:

• 1st LEVEL, 1st Pre-Alarm 13 % L.E.L/200 ppm.
• 2nd LEVEL, Main Alarm at20% L.E.L./300 ppm.

Other technical features make this gas controller extremely versatile and reliable; for example, by using a series of micro-switches it is possible to:

• Select or disable a sensor when not installed or faulty;
• Select the gas type to be detected (toxic or explosive);
• Choose the relay functioning mode (pulsed or continuous);
• Choose deadband exclusion mode.
