Tamper-Resist Feature
This is an alert to notify consumers the unit has been unplugged or has
come loose from the outlet. This feature is not activated for two minutes
after power is first supplied to give you time to plug the unit in after
activating the battery. This feature is also disabled once the battery volt-
age has reached a level to cause a low battery warning chirp. This can
be defeated for two minutes by pressing the Test button while the unit
is removed from the plug to allow the battery to be changed without
the 85dB alarm sounding. The feature can also be disabled by pressing
in the Tamper-Resist Activation switch and moving the disable slide
towards the switch. Use the included screw to secure the battery cover
and increase tamper resistance.
1. Information About Carbon Monoxide
2. Product Features and Specifications
Because carbon monoxide is a cumulative poison, long-term exposures
to low levels may cause symptoms, as well as short-term exposures to
high levels. This Kidde unit has a time-weighted alarm – the higher the
level of CO present, the sooner the alarm will be triggered.
This CO alarm can only warn you of the presence of CO. It does not
prevent CO from occurring, nor can it solve an existing CO problem. If
your unit has alarmed and you’ve provided ventilation by leaving your
windows and doors open, the CO buildup may have dissipated by the
time help responds. Although your problem may appear to be
temporarily solved, it’s crucial that the source of the CO is determined
and that the appropriate repairs are made.
This CO alarm is designed to act as a 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. This alarm will not
monitor CO levels while in an error condition.
CO alarms can only sense CO that reaches the unit’s sensor. It’s possible
that CO may be present in other areas without reaching the alarm. The
rate and ability that which CO reaches the alarm may be affected by:
• Doors or other obstructions.
• Fresh air from a vent, an open window or other source.
• CO being 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 these reasons, we recommend you provide complete coverage by
placing a CO alarm on every level of the home. Please carefully read all
information on properly installing this CO alarm.
CO alarms should not be used to detect the presence of natural gas
(methane), propane, butane, or other combustible fuels.
