Commissioning
It is strongly recommended that this detector should be commissioned by Duomo Commissioning Engineers or
engineers approved by Duomo to carry out this work. A quotation for commissioning or service will be provided upon
request. Fax site details and preferred date for commissioning to 01905 774296 and the Duomo Service Department will
fax back confirmation.
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.
It is prudent to make electrical connection to the detector terminal plus when withdrawn and leave the plug off the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.
