Peak Level Memory (model KN-COP-IC 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 Peak Level
Memory Reset or power up. The Peak Level display feature will display
levels 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 nor-
mal, 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.
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.
