This Kidde CO alarm meets the alarm response
time requirements which are as follows:
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 safeguard individuals with specific
medical conditions. If in doubt, consult a medical practitioner. Individuals with
medical problems may consider using warning devices which provide audible
and visual signals for carbon monoxide concentrations under 30 ppm.

How the Unit Determines When to Alarm
Your Kidde CO alarm uses advanced technology to monitor the environment
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 micro-
computer is calibrated to trigger the unit’s alarm before most people would
experience any symptoms of carbon monoxide poisoning. Because carbon
monoxide is a cumulative poison, long-term exposures to low levels can
cause symptoms, as well as short-term exposures to high levels. Your Kidde
unit has a
time weighted alarm, so the higher the level of carbon monoxide
present, the sooner the alarm will be triggered.

and table top applications.
Alarm: 85+ dB at 10’ @ 3.4 ± 0.5 KHz pulsing alarm.
Technical Information
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). Depending on the ambient condition (temperature, humidi-
ty) and the condition of the sensor, the
alar
m
readings may vary.
The digital reading tolerances are:
Ambient: 80˚ F (+/- 10˚ F), atmospheric pressure +/- 10%, 40% +/- 3% relative
humidity.
