It is activated when the sensor with the highest concentration of toxic gas in the area
communicates for a time greater than the ventilation 2 activation delay, values greater than
or equal to the configured ventilation 2 concentration level.
It is deactivated when the previous toxic gas concentration is lower, for a time greater than
the alarm shutdown delay, at the ventilation 2 concentration level.
In the event that the zone alarm is activated, ventilation 2 of that zone will also be activated.
In this case, for ventilation 2 in the zone to be deactivated, it will be necessary to wait for
the alarm to deactivate and for the toxic gas concentration in the zone to be lower than the
ventilation 2 concentration for a time greater than the ventilation 2 stop time.
7. Zone
Outputs for the connection of the detection zones of the control panel.
The zone output delivers approximately 24 Vdc, which is protected by protection systems in
case of short circuit. The toxic gas thresholds with which the area works are described in Table
2 and Table 3, depending on whether it is the MCO120DVB model or not.
All outputs will be made with 2 x 1.5 mm BRAIDED AND SHIELDED HALOGEN-FREE CABLE
for distances up to 800 m. For greater distances 2 x 2.5mm BRAIDED AND SHIELDED
HALOGEN FREE CABLE up to 1500 m.

Panel control language
Together with the panel control two labels without stickers in different languages are
incorporated, which describe the main functionalities of the indicators and buttons on the control
panel. Once the required language has been selected, insert both labels at the bottom off the
cover, as indicated by the arrows in Figure 8. When the labels have been inserted, the language
selection process is finished.
