1. Information About Carbon Monoxide
Carbon Monoxide PPM Levels
(model 900-0230 with digital display only)
Model 900-0230 is equipped with a digital display that shows levels of
CO (displayed in PPM – parts per million). Learn the difference between
dangerous, high, mid and low levels.
Dangerous Levels:
When someone is experiencing symptoms of CO poisoning and CO
readings are generally above 100 PPM. Anytime someone is experiencing
the symptoms of CO poisoning this should be treated as an emergency.
See “What to do When the Alarm Sounds” (inside front cover).
High Levels:
Generally above 100 PPM, with no one experiencing symptoms. This
should be treated as an urgent situation. See “What to do When the
Alarm Sounds” (inside front cover).
Mid Levels:
Generally between 50 PPM to 100 PPM. This should be cause for
concern and should not be ignored or dismissed. See “What to do
When the Alarm Sounds” (inside front cover).
Low Levels:
Generally below 50 PPM. Kidde recommends you take action to
eliminate the source of CO. See “What to do When the Alarm Sounds”
(inside front cover).
IMPORTANT: Model 900-0233 does not have a digital display and
does not display carbon monoxide levels in PPM. If the alarm
sounds, it should be treated as a potentially serious condition.

Possible Sources of Carbon Monoxide
Inside your home, appliances used for heating and cooking are the most
likely sources of CO. Vehicles running in attached garages can also
produce dangerous levels of CO.
CO can be produced when burning any fossil fuel, such as gasoline,
propane, natural gas, oil and wood. It can be produced by any fuel-
burning appliance that is malfunctioning, improperly installed, or not
ventilated correctly, such as:
• Automobiles, furnaces, gas ranges/stoves, gas clothes dryers, water
heaters, portable fuel burning space heaters and generators,
fireplaces, wood-burning stoves and certain swimming pool heaters.
