BX444-Mc Toxic and Explosive Gas Detector Control Unit for Industrial use

Cod. BX444-Mc - Toxic and Explosive Gas Detector Control Unit for Industrial use

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 and Oxigen, through the connection of 4 remote probes. Thanks to this and its other features BX444Mc is suitable for civil use, industrial use and small underground car parks.
The BX444Mc 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.
Other technical features make this control unit extremely versatile and reliable; for example, by using a series of microswitches it is possible to:
Select or disable the probe when not installed or faulty;
Select the type of gas to be detected (toxic or explosive);
Choose the relay functioning mode (pulsed or continuous);
Choose selection of the intrinsic safety
