When detector , detects gas leakage ,you will be command fan or gas interrupt valve automatically,
using relay outputs. CD 310/330R has 1A total current relay for NC&NO relay outputs. Connecting
one or many equipments, not exceeding total value of 1A current. Above 1A current connect suitable
contactor.Connection of automaticlly commanding equipments notr line to the detectors Com
terminal.
On the other line; Operating Operating automatically command equipment in the alarm situation,
connect detector’s NC terminal(Figure 7), interrupt operating equipment automatically connect NO
terminal(Figure 8).
According to the instructions above, operating or interrupt operating some equipments(Figure 9). On
the other hand operating equipments makes danger during gas leakage have to be considerated.
If the detector operating by connecting panel, automatic operation should be command by the
panel.

Connections
Panel Connections
Power connection of the detector, from a panelor a power supply by the double ribbed cable which has
radius of 1.5square milimeters.
Sending alarm signal to the panel, by the connection of double ribbed cable to the relay outputs.
For using relay outputs(NC&NO), read instruction manual of panel. According to the instruction manual
of panel, you may use suitable alarm Resisto(B) or end of line resistor(A), for the relay output
connections. Connection Schemas are Figure 5 and Figure 6 . For suitable resitors and connection
schemas of panel, look inside instruction manual of panel.
