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-LP with digital
display: The display will show three “eights” and then show a number
– and then show a number between 150 and 300). 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.
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 as long as dangerous 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).
