Kidde KN-COU-B - Manual (Page 17)

When the Peak Level button is pressed and held, the display shows the
highest CO reading taken by the CO monitor since its last reset or power
up. In this example 120 PPM was the maximum level of CO recorded
since the unit was last reset.
The Peak Level display feature will display levels
between 10-999 PPM. The Peak Level feature is
helpful in identifying if you have had a CO reading
since resetting the alarm.
Concentrations of CO between 1 and 30 PPM can
occur in everyday conditions. Concentrations of CO
below 30 PPM may be an indication of a transient
condition that may appear today and never reappear. Some CO condi-
tions may start out as low level leaks but could develop into CO concen-
trations that may become life threatening.
If this happens, the CO monitor will detect the life threatening level and
alarm, notifying you and others of the conditions. DO NOT ignore high
concentration readings above 30 PPM or a CO monitoring device
that is in alarm.
Peak Level Memory Reset
Press the Peak Level button; with the button still pressed, press the
Test/Reset button for two seconds and release. The number on the dis-
play will turn to “0”, the memory will be cleared and the alarm will
begin monitoring for CO. The Peak Level memory is also reset when the
unit loses power.
Carbon Monoxide Monitor Indicator
When the monitor senses a life threatening level of CO, the unit will
emit a loud alarm pattern. The alarm pattern is 4 quick beeps followed
by 5 seconds of silence, repeating for as long as dangerous conditions
exist. The red LED will flash the same pattern and the digital display will
indicate CO concentrations in parts per million (PPM).
Testing
To test the monitor, press and release the Test/Reset button. If the unit is
operating properly, you will hear 4 quick beeps – followed by 5 seconds
of silence – followed by 4 quick beeps. The display will show three “---”
two to three times and then show “888”. The red LED will flash along
with the beeps. Within several seconds the unit will display “0” and
return to monitoring for CO.
Note: You do not need to press the Test button to take a CO reading.
