Commisioning

It is strongly recommended that this SGM595 gas sensor and connected detection system is commissioned and serviced 

by Duomo Commissioning Engineers or engineers approved by Duomo. A quotation for commissioning or service will be 

provided upon request.

Email site details and preferred date for commissioning or service to [email protected] to the Duomo Service Department. 

Or call 

+44 1905 797989

The benefits of this equipment being commissioned by Duomo are:

• 

On board spares -  If for whatever reason this equipment doesn't function correctly Duomo engineers will have spares 

on board to ensure that the commissioning is successful.

• 

A Duomo Commissioning Certificate is provided - A certificate from the original maufacturer ensures that the commisioning 

or servicing carried out is at a high professional standard by a competent and qualified service engineer.

It is prudent to make electrical connection to the detector terminal plus when withdrawn and leave the plug off the detector 

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.

Maintenence

This sensor must be function checked as described above using calibrated test gas every 6 months. 

To arrange for a Duomo engineer to conduct this work or to arrange a service contract please call
