Limitations of CO Alarms
1. CO alarms may not wake up all individuals. If children or others do not readily awaken to the sound of the CO alarm, or if there
are infants or family members with mobility limitations, make sure that someone assists them in the event of an emergency.
2. This CO alarm will not sense carbon monoxide that does not reach the sensor. This CO alarm will only detect CO that reaches
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, it is recommended that you install a CO alarm in each
bedroom and in the hallway between them.
3. CO alarms may not sense CO on another level of the house. 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 an adequate warning. Complete coverage is
recommended by placing CO alarms on each level of the house.
4. CO alarms may not be heard. The alarm buzzer noise level is over 85 dB at a distance of 3 m (10 feet). However, if the CO alarm
is installed outside the bedroom, it may not awaken a sound sleeper or one who has recently used drugs or has been drinking
alcohol. This is especially true if the door is closed or only partially 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, stereos, radios, televisions, air conditioners, or other
appliances may even prevent alert persons from hearing the alarm horn. This CO alarm is not intended for people who are
hearing impaired.

5. 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
possible sources of incomplete combustion. The installation of a smoke alarm is required for an early warning of fire.
6. CO alarms are not a substitute for life insurance. Though these CO alarms warn against increasing CO levels, we do not
warrant or imply in any way that they will protect lives from CO poisoning. Homeowners and renters must still insure their
lives.
7. 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 are strongly recommended to test your CO
alarm weekly.
8. 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 of rising CO levels if the CO is coming from a remote part of the house, or is at
some distance from the CO alarm.
