When the carbon monoxide gas dissipates, the NoCO alarms will silence automatically. The
Alarm LED (red) on the NoCO Control Unit will emit a short flash once every 10 seconds to
advise that there has been a carbon monoxide leak.
USER LOCK OUT
When the boiler is switched off as a result of a carbon monoxide leak, a Gas Safe engineer
will be required to reset the boiler in order to switch it back on.
The Gas Safe engineer must, before resetting the boiler, fully investigate the cause of
the carbon monoxide alarm event and take all appropriate measures to remove any
further risk.
