7. Model KN-COP-IC (with digital display)
Operating Characteristics
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 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 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.

8. Maintenance

NOTE: This unit is sealed. The cover is not removable.
Due to the loudness of the alarm, we suggest that you place your
fingers over the sounder opening while testing your alarm.
CAUTION: Continuous exposure to the high sound level of this
alarm over an extended period of time may cause hearing loss.
Testing
To test the alarm, press the Test/Reset button. If the unit is operating
properly, you should hear 4 quick beeps – followed by 5 seconds of
silence – followed by 4 quick beeps. (For model KN-COP-IC with digi-
tal display: The display will show three "eights" and then show a num-
ber – usually around 200). The red LED will flash along with the beeps
and the amber LED will illuminate. Within several seconds the unit will
return to monitor for CO.
If interconnected to Kidde smoke alarms, pressing the Test/Reset button
on the CO alarm will have no effect on the smoke alarms. The smoke
