8-zone detection control unit with box

The control unit was designed and built according to European Regulations to verify the presence of gas in a versatile way thanks to the possibility of connecting up to 8 conventional sensors. The control unit has both pre-alarm relays and general alarm relays.

The control unit has two levels of danger, which are:

LEVEL I, pre-alarm. This data is variable, it is possible to modify the intervention of the pre-alarm, probe by probe, based on the type of system to be controlled, the level can be selected from 3% to 16% of the LEL or from 45 to 240 ppm

LEVEL II, general alarm. It is set at 20% of the LEL or 300 ppm LEVEL II, general alarm. It is set at 20% of the LEL or 300ppm

Thanks to the most innovative technologies, this gas detection control unit is suitable for installation in industrial environments and underground car parks, applying the "DM 01/AC02/1986.
