4.1.2 HIGH CO ALARM
Should the CO reading rise above 2,000ppm a continuous series of Alarm Beeps
will be heard. This Alarm alerts the user that there is a high concentration of CO
and that there may be a potential problem with the appliance. The instrument will
continue to monitor CO up to 10,000ppm but the longer the probe is left attached
to the instrument sampling at these high levels the longer the recovery time back
to ambient air before the instrument will be able to be switched off (see 4.1.7
–
Failsafe Turn Off).
