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 foolproof. CO alarms have a limited operational life.
You must test your CO alarm weekly to insure that it is operating
properly at all times.
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 at which CO reaches the alarm may be affected by:
• Doors or other obstructions.
• Fresh air from a vent, an open window or other source.
• The presence of CO on one level of the home and a CO alarm
installed on a different level. (For example, CO in the basement
may not reach an alarm on the second level.)
For these reasons, we recommend you provide complete coverage
by placing a smoke/CO alarm on every level of the home. Please
carefully read all information in the Installation Guide section on
properly installing this smoke/CO alarm.
CO alarms should not be used to detect the presence
of natural gas (methane), propane, butane or other combustible
fuels.
Instruct children never to touch, unplug or otherwise interfere with
the alarm. Warn children of the dangers of CO poisoning.
