Electrical Installation
If the CO100Ar 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 CO100Ar 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.

The benefits of this equipment being commissioned by Duomo are:
The 3 year guarantee period will start from the date of commissioning and not from the date of manufacture
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It is prudent to make electrical connection to the sensor terminal plug when withdrawn and leave the plug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.
