Battery Backup:
A 9V battery is needed. If battery is low or
missing while the unit is plugged into a 120V outlet,
an "Lb" message will display which will blink
alternately with a the CO reading every second and
the sounder will chirp every 15 seconds.
Unit Malfunction:
"Err" error message will display. Intermittent
alarm will sound every 30 seconds.
Test/Reset Button:
Test button verifies proper unit operation and resets
the unit in the event of a CO alarm.
Peak Level Memory Button:
When pressed, LED will display the highest CO
ppm level detected since unit was powered up or
since unit was reset with test button. Reading will
be stored in memory as long as unit is not reset
or unplugged. Any CO concentration detected from
11-999 will be displayed

Warranty: Five-year warranty from date of purchase against
defects in material and workmanship.

How the Unit Determines When to Alarm

Your Kidde CO alarm uses advanced technology to monitor the envi-
ronment in your home and warn you of unacceptable levels of carbon
monoxide. An internal microcomputer works together with the carbon
monoxide sensor inside the alarm to determine the levels of carbon
monoxide in the air and to calculate the rate that CO would be absorbed
into the human body. The microcomputer is calibrated to trigger the
unit's alarm before most people would experience any symptoms of car-
bon monoxide poisoning. Because carbon monoxide is a cumulative poi-
son, long-term exposures to low levels can cause symptoms, as well as
short-term exposures to high levels. Your Kidde unit has a time weight-
ed alarm, so the higher the level of carbon monoxide present, the soon-
er the alarm will be triggered.
This Kidde CO alarm meets these alarm response times:
At 70 ppm, the unit must alarm within 60-240 minutes.
At 150 ppm, the unit must alarm within 10-50 minutes.
At 400 ppm, the unit must alarm within 4-15 minutes.
WARNING: This device is designed to protect individuals from
acute effects of carbon monoxide exposure. It will not fully safe-
guard individuals with specific medical conditions.
If in doubt, consult a medical practitioner.
Accuracy of the Digital Display
Each Kidde CO Alarm is calibrated at a CO concentration of 150 ppm in
air, at 80˚ F (+/- 10˚ F) and 40% (+/- 3%) relative humidity. Depending on
the ambient condition (temperature, humidity) and the condition of the
sensor, the alarm readings may vary.
The digital reading tolerances are:
Ambient: 80˚ F (+/- 10˚ F), atmospheric pressure +/- 10%, 40% +/-
3% relative humidity.
