Carbon Monoxide Safety
CO alarms provide early warning of the presence of car-
bon monoxide, usually before a healthy adult would expe-
rience symptoms. This early warning is possible, however,
only if your Kidde CO alarm is located, installed and main-
tained as described in this manual.
This CO alarm is designed to act as a continuous monitor;
it is not designed for use as a short-term testing device to
perform a quick check for the presence of CO.
CO alarms have limitations. Like any other electronic
device, CO alarms are not fool-proof. CO alarms have a
limited operational life. You must test your CO alarm
weekly, because it could fail to operate at any time.
If your CO alarm fails to test properly, or if its self-
diagnostic test reveals a malfunction, immediately have the
unit replaced.
CO alarms can only sense CO that reaches the unit's
sensor. Carbon monoxide may be present in other areas
without reaching the alarm. The rate at which CO reaches
the unit may be affected by doors or other obstructions. In
addition, fresh air from a vent or open window or any
other source may prevent CO from reaching the sensor.
Please observe cautions in Installation on page 5.
CO could be present on one level of the home and not
reach a CO alarm installed on a different level. For
example, CO in the basement may not reach an alarm on
the second level, near the bedrooms. For this reason, we
recommend you provide complete coverage by placing a
CO alarm on every level of the home.
CO alarms should not be used to detect the presence of
natural gas (methane), propane, butane, or other
combustible fuels.
