Part One Your Kidde Carbon Monoxide Alarm
How to Care for Your Alarm
To keep your alarm in good working order, you must follow
these simple steps:
Test the alarm once a week by pressing the Test/Reset
button (see page 8).
Vacuum the alarm cover once a month to remove
accumulated dust. Use the soft brush attachment of your
vacuum cleaner, and unplug the alarm from the electrical
outlet before vacuuming.
Instruct children never to touch, unplug or otherwise interfere
with the alarm. Warn children of the dangers of CO poisoning.
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 alarm. Paint will seal the vents and
interfere with proper sensor operation.
Do not mount the alarm directly above or near a diaper pail,
as high amounts of methane gas can cause temporary
readings on the digital display.
Note: If you will be staining or stripping wood floors or furni-
ture, painting, wall-papering, or using aerosols or adhesives for
a do-it-yourself project or hobby, before you begin: Remove the
alarm to a remote location to prevent possible damage to or contam-
ination of the sensor. You may wish to unplug the alarm and store
in a plastic bag during the project.
The following is a list of substances that at high levels can affect
the sensor and cause temporary readings on the digital display
that are not carbon monoxide readings:
Methane, propane, iso-butane, ethylene, ethanol, alcohol, iso-
propanol, benzene, toluene, ethyl acetate, hydrogen, hydrogen sulfide,
sulfur dioxides.
Also most aerosol sprays, alcohol based products, paints, thinners,
solvents, adhesives, hair sprays, aftershaves, perfumes, auto exhaust
(cold start) and some cleaning agents.
The Peak Level Memory Button
Although the peak level feature will display levels below 30 PPM,
these levels will not result in an alarm no matter how long the
device is exposed to these levels.
The peak level feature is helpful in identifying low level CO occur-
rences below 30 PPM. Although the unit will not automatically
display levels below 30 PPM, it will detect and store these read-
ings in memory. By pressing the peak level button, concentration
levels as low as 11 and up to 999 PPM will be displayed.
Concentrations of CO between 0 and 30 PPM can often occur in
normal, everyday conditions. Concentrations of CO below 30
PPM may be an indication of a transient condition that may
appear today and never reappear. Just a few examples of condi-
tions and/or sources that may cause low level readings are heavy
automobile traffic, a running vehicle in an attached garage, an
appliance that emits CO when starting up, a fire in a fireplace or
charcoal in a nearby barbecue. A temperature inversion can trap
CO generated by traffic and other fuel burning appliances caus-
ing low level readings of CO.
Normally, the digital display will read 0 and under certain con-
ditions you may notice levels of 30 or more for short periods of
time, by using the Peak level memory feature on the Kidde CO
alarm you can view concentrations of CO between 11 and 30
PPM. Use the low-level concentrations shown in memory as a
tool in identifying the source of the CO. It may be helpful to pur-
chase additional Kidde CO Alarms to place in different locations
throughout your house to isolate the CO source. Monitor the CO
concentrations shown in the peak level memory to see if readings
occur in certain areas at certain times of the day, or near a par-
ticular appliance.
Once the source is located, correcting the problem may be as easy
as opening a window, venting an appliance, backing a car out of
the garage a safe distance from living quarters, closing the
garage door, and letting the car warm up outside. It could be
possible that a weather condition caused the low-level reading
and the condition may or may not happen again.
Some CO conditions may start out as low level leaks but could
develop into CO concentrations that could become harmful. If
this happens, the CO alarm will detect the dangerous level and
alarm, notifying you and others of the conditions. DO NOT
ignore high concentration readings above 30 PPM or a CO alarm-
ing device that is in alarm. Refer to page 12 for more details.
CO concentrations displayed below 30 PPM in "Peak Level"
memory are for reference only and the accuracy of the concen-
tration shown may not be as accurate as noted on page 14.
To Reset the Peak Level Memory
Step 1. Press the peak level button.
Step 2. With the peak level button still pressed, press the
test/reset button for two seconds and release.
The number on the display will turn to 0. The memory has
now been cleared and the alarm will begin monitoring for CO
within a few minutes.
