Control Unit from 1 to 2 Conventional sensors BX280-AX
Rev.1
Belonging to
Through the connection of 2 remote sensors, the BX280-AX control unit 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 BX280-AX is suitable for civil and industrial applications.
The BX280-AX control unit has two danger levels:
1
st
LEVEL, 1
st
Pre-Alarm. It’s set at 13 % of L.E.L. for all sensors.
2
nd
LEVEL, Main Alarm. It’s set at 20% of L.E.L.
Other technical features make this control unit 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
A TEST button checks the efficiency of both the unit and connected probe to ensure total control of the BX280-
AX
Thanks to the Omega-type format, small and large systems can be built by exploiting the modularity of the
DIN rail in the previously set electrical panels.
In addition to the alarm signal light, it is fitted with an internal buzzer.
