4 zones Control Unit 144x144
The BX444-Mc control unit has been designed and built according to European regulations to flexibly detect the presence of toxic and/or explosive gas, through the connection of 4 remote probes.
A microprocessor is used to create a complete surveillance and control system with maximum flexibility. Thanks to this and its other features BX444-Mc is suitable for civil use, industrial use and small underground car parks.
The BX444-Mc control unit has three danger levels:
1st LEVEL, 1st Alarm. This was set to 8 % of L.E.L. (120ppm) for all probes.
2nd LEVEL, 2nd Alarm. This was set at 13% of L.E.L. (200ppm) for all probes.
3rd LEVEL, Main Alarm. This was set at 20 % of L.E.L. (300ppm) for all probes.
