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. The battery back-up is for emergency use only!
CO Alarms for Solar or Wind Energy users and battery backup power systems:
AC powered CO Alarms
should only be operated with true or pure sine wave inverters. Operating this CO Alarm with most battery-pow-
ered UPS (uninterruptible power supply) products or square wave or “quasi sine wave” inverters
will damage
the Alarm
. If you are not sure about your inverter or UPS type, please consult with the manufacturer to verify.
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 hear-
ing 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 malfunc-
tioning 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 lev-
els, 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.
