Duomo CO200 Manuel
Electrical Installation
If the CO200 Duct is to be used to monitor possible leakage of carbon monoxide in boiler rooms due to
spillage or damaged or unsuitable flue systems, it is advisable to connect the sensor directly to a Duomo gas
control panel. These are safety devices and are designed to give audible alarms and automatically provide
latched electrical isolation of associated gas safety shut off valves.
The CO200 Duct is also suitable for carbon monoxide sensing in car parks and can be connected either to
Duomo gas control panels or to Building Management Systems (BMS). The sensor can be located up to 100m
from the gas detector. Cable size should be 1mm csa. If the sensor cables are run seperately in specific conduit
it is not essential to use screened cable.
However, if the cables are routed through conduit or trunking containing other wiring the use of screened
cable is advisable. The wiring should be performed by a qualified person in accordance with current
regulations.The plug in terminal rail makes installation easy and quick.

On board spares. If for whatever reason this equipment doesn't function correctly Duomo engineers will carry spares
to ensure that the commissioning is successful
A Duomo Commissioning Certificate is provided
It is prudent to make electrical connection to the sensor terminal plug when withdrawn and leave the plug
disconnected from the sensor so that the Duomo Engineer is the first to power up the unit on site. This allows wiring to
be checked prior to commissioning and avoids damage due to incorrect connection. Guarantees for this product will
become void if damage is caused by the installer.
