CHAPTER 8: General Limitations Of CO Alarms
This CO alarm is intended for residential use. It is not intended for use in industrial applications
where Occupational Safety and Health Administration (OSHA) requirements for carbon monoxide
detectors must be met.
CO alarms will not work without power. This CO
alarm requires a continuous supply of AC power,
and a fresh, correctly installed 9V battery to power
the battery back-up.
This CO alarm will not sense carbon monoxide
that does not reach the sensor. This CO alarm
will only sense CO at the sensor. CO may be
present in other areas. Doors or other
obstructions may affect the rate at which CO
reaches the CO alarm. For this reason, if
bedroom doors are usually closed at night, we
recommend you install a CO alarm in each
bedroom and in the hallway between them.
CO alarms may not sense CO on another level of the
home.
For example, a CO alarm on the second
level, near the bedrooms, may not sense CO in the
basement. For this reason, one CO alarm may not
give adequate warning. Complete coverage is
recommended. Place CO alarms on each level of
the home.
CO alarms may not be heard. The alarm horn
loudness meets or exceeds current UL standards
of 85 dB at 10 feet. However, if the CO alarm is
installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used
drugs or has been drinking alcoholic beverages.
This is especially true if the door is closed or only
partly open. Even persons who are awake may
not hear the alarm horn if the sound is blocked
by distance or closed doors. Noise from traffic,
stereo, radio, television, air conditioner, or other
appliances may also prevent alert persons from
hearing the alarm horn. This CO alarm is not
intended for people who are hearing impaired.
CO alarms are not a substitute for a smoke
alarm.
Although fire is a source of carbon
monoxide, this CO alarm does not sense smoke
or fire. This CO alarm senses CO that may be
escaping unnoticed from malfunctioning furnaces,
appliances, or other sources. Early warning of fire
requires the installation of smoke alarms.
CO alarms are not a substitute for life insurance.
Though these CO alarms warn against increasing
CO levels, BRK Brands, Inc. does not warrant or
imply in any way that they will protect lives from
CO poisoning. Homeowners and renters must
still insure their lives.
CO alarms have a limited life.
Although the CO
alarm and all of its parts have passed many
stringent tests and are designed to be as
reliable as possible, any of these parts could fail
at any time. Therefore, you must test your CO
alarm weekly.
CO alarms are not foolproof. Like all other
electronic devices, CO alarms have limitations. They
can only detect CO that reaches their sensors. They
may not give early warning to rising CO levels if the
CO is coming from a remote part of the home, away
from the CO alarm
