6. Model KN-COPP-B (with digital display)
Operating Characteristics
Peak Level Memory (model KN-COPP-B 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
between 11-999 PPM. Although the Peak Level fea-
ture 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.
If this happens, the CO alarm will detect the dangerous level and alarm,
notifying you and others of the conditions. DO NOT ignore high con-
centration 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 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.
7. Alarm Characteristics
Carbon Monoxide Alarm Indicator
When the alarm senses a dangerous 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 4 minutes – and then 4 quick beeps
once every minute as long as dangerous CO conditions exist. The red
Alarm LED will flash the same pattern and the digital display (where
equipped) will indicate CO concentrations in parts per million (PPM).

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 will hear 4 quick beeps – followed by 5 seconds of silence
– followed by 4 quick beeps. (For model KN-COPP-B with digital dis-
play: The display will show three "eights" and then show a number –
usually around 200). The red LED will flash along with the beeps. Within
several seconds the unit will return to monitor for CO. Note: You do
not need to press the Test button to take a CO reading.
Maintenance Tips
To keep your alarm in good working order, you must follow these steps:
• Test the alarm once a week by pressing the Test/Reset button.
• Vacuum the alarm cover once a month to remove accumulated dust.
• Never use detergents or solvents to clean the alarm. Chemicals can
permanently damage or temporarily contaminate the sensor.
• Avoid spraying air fresheners, hair spray, paint or other aerosols near
the alarm.
• Do not paint the unit. Paint will seal the vents and interfere with
proper sensor operation.
