1. Re-fit all NoCO alarms back on their baseplates.
2. Wait at least 5 minutes for the system to re-establish the network. Once the Control
Unit has recognised the NoCO alarm is back on its baseplate, the Fault LED (yellow) will
change from a rapid flash to one flash every 10 seconds.
3. Press the reset button on the NoCO Control Unit briefly. The Fault LED (yellow) will stop
flashing and the boiler supply will come back on again.
WHAT WILL HAPPEN IN THE EVENT OF A
CARBON MONOXIDE LEAK BEING DETECTED?
In the event that a NoCO alarm detects dangerous levels of carbon monoxide (as stated in
EN:50291-1:2010), the system will enter alarm mode. The Alarm LED (red) on the NoCO
Control Unit will flash continuously, once per second.
The boiler will switch off and User Lock Out will set.
The system will activate:
• After a period of between 60 and 90 minutes when exposed to a minimum of 50ppm* of
carbon monoxide.
• After a period of between 10 and 40 minutes when exposed to a minimum of 100ppm* of
carbon monoxide.
• Within 3 minutes when exposed to a minimum of 300ppm* of carbon monoxide.
The Alarm LED (red) on the Control Unit will flash continuously, once per second.
All NoCO alarms will sound a pattern of 4 loud beeps continuously and the Alarm LED (red) of
the NoCO alarm which detected carbon monoxide will also flash.
*ppm = parts per million. This is a measure of the concentration of carbon monoxide in the air.
The above alarm trigger points should be viewed in the context of the following table.
