Positioning Sensors

Carbon monoxide has speci c gravity of 0.97 and is therefore

slightly lighter than air.

However for positioning purposes, at the concentrations of

carbon monoxide relating to the detector alarm thresholds, the

resultant combination of carbon monoxide and air will neither

rise or fall.

The best position to mount the CO100Ar is 1.6m above ground

level. The image below shows the suggested position for the

CO100Ar in a boiler room.

For car parks, 1.6m above ground level is still recommended.

If you require assistance regarding locating sensors please call

our Droitwich factory on (01905) 797989 or fax a drawing of

your application to (01905) 774296 and we will advise

accordingly.

Important Notes

The installation of this gas detector does not release

the user from observing all the regulations

concerning the characteristics, installation and the

use of gas appliances; the ventilation of the

environment and the elimination of combustion

products in accordance with local recommendations,

regulations and byelaws.

For any damage caused to people, property or

animals resulting from incorrect connection,

installation or application of this gas detector Duomo

will not be held responsible or liable.

Replacing Sensor

When replacing sensors NEVER seperate a sensing

head from the PCB. The sensor has been calibrated

using only that particular board and therefore will not

function correctly with any other.
