1. Alarm:
Dry contact output with a capacity of 1A (30Vdc).
It is activated when the concentration measured by any sensor in the zone communicates
toxic gas concentration values, for a time greater than the alarm activation delay, greater
than or equal to the configured alarm concentration level.
It is deactivated when the previous gas concentration is lower, for a time greater than the
alarm stop delay, at the configured alarm concentration level.
2. Fault:
Dry contact output with a capacity of 1A (30Vdc).
It will be activated whenever there is a fault in the system or there is no power, indicating
the fault status through its corresponding LED (for more information see Figure 9 and Table
4).
It is only deactivated when there is no fault in the system and the control panel is powered
(the Common-Normally Open (NO) contact of the relay is electrically open).
3. 30V Output:
Auxiliary output of 30Vdc with a maximum capacity of 0,5A
This output is protected by a self-resetting fuse and supervises voltage, excess
consumption and crossed line. Allows powering of devices such as sirens.
4. Batteries (DVB model):
In the case of the DVB model, this strip will be connected to the batteries.
Through this connection, the batteries are charged, as well as the monitoring of their status.
Battery charging is compensated based on battery temperature. This output/input is
protected with a fuse and against polarity reversal. The box has space for 2x12Vdc 2Ah.
The connection will be made as indicated as Figure 7.
Respect the polarity of the batteries for correct operation
5. Ventilation 1:
Dry contact output with Common-Normally Open (C-NO) contact with a capacity of 1A
(30Vdc).
It is activated when the sensor with the highest measured concentration of toxic gas in the
area communicates, for a time greater than the ventilation 1 activation delay, values greater
than or equal to the configured ventilation 1 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 1 concentration level. In the event that the
zone alarm is activated, ventilation 1 of that zone will also be activated. In this case, for
ventilation 1 to be deactivated in the zone, it will be necessary to wait for the alarm to
deactivate, and then for the concentration of ventilation 1 for a time greater than the stop
time of the ventilation 1.
6. Ventilation 2:
Dry contact output with Common-Normally Open (C-NO) contact, with a capacity of 1A
(30Vdc).
