TO TEST THAT THE NoCO ALARMS WILL
SWITCH OFF THE BOILER IN THE PRESENCE
OF A CARBON MONOXIDE LEAK
In order to be able to see the Control Unit indicators at the same time as pressing the test
button on the NoCO alarms, it is likely you will need two people to perform this operation.
1.
Press and hold the test button on the NoCO Control Unit for more than 2 seconds and
the boiler power will switch off.
2.
Press the reset button on the NoCO Control Unit and the boiler power will switch on.
3.
Test each NoCO alarm individually – the Alarm LED (red) will flash on the NoCO
Control Unit for 60 seconds, but the boiler will remain on.
Note: the system can be repeatedly tested – the NoCO Control Unit will only “lock out” the
boiler in the presence of carbon monoxide.
The NoCO alarms and the NoCO Control Unit should be tested weekly.
REMOVING YOUR NoCO ALARM FROM ITS
BASEPLATE
Removing your NoCO alarm from its baseplate (for redecorating for example) will disengage
the battery so your alarm will stop functioning.
IMPORTANT:
Removing your NoCO alarm from its baseplate will shut off your boiler. This is
a necessary safety precaution and no attempt should be made to override this feature. You
will see that the Fault LED (yellow) on the NoCO Control Unit will flash once every 3 seconds
which indicates that one or more alarms is missing from the network. When you are ready to
replace the alarm back into position, you can restart the boiler as follows:
