Peak Level Memory (model KN-COPP-B-LS-UK (900-0230) only)
When the Peak Level button is pressed and held, the display shows the
highest CO reading taken by the CO alarm since its
last reset or power up. In this example 120 PPM was
the maximum amount of CO recorded since the unit
was last reset.
The Peak Level display feature will display levels
Sample Peak
Level Reading
between 11-999 PPM. Although the Peak Level
feature will display levels below 30 PPM, these levels
will not result in an alarm no matter how long the device is exposed to
these levels. 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 often occur in normal,
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 conditions may start out as low level leaks but could
develop into CO concentrations that may become harmful.
If this happens, the CO alarm will detect the dangerous level and alarm,
notifying you and others of the conditions. DO NOT ignore high
concentration readings above 30 PPM or a CO alarming 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 display
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.
