Where to Install Co alarms
The National Fire Protection Association (NFPA) recommends that a CO
Alarm should be centrally located outside of each separate sleeping
area in the immediate vicinity of the bedrooms. For added protection,
install additional CO Alarms in each separate bedroom, and on every
level of your home.
If your bedroom hallway is longer than 40 feet (12 meters), install a CO
Alarm at BOTH ends of the hallway.
In a Single-level Home:
• InstallatleastoneCOAlarmnearorwithineachseparatesleeping
area.

• This CO Alarm is designed for use inside a single-family
home or apartment. It is not meant to be used in common
lobbies, hallways, or basements of multi-family buildings
unless working CO Alarms are also installed in each family
living unit. CO Alarms in common areas may not be heard
from inside individual family living units.
• This CO Alarm alone is not a suitable substitute for complete
detection systems in places which house many people, like
hotels or dormitories, unless a CO Alarm is also placed in
each unit.
• DO NOT use this CO Alarm in warehouses, industrial or
commercial buildings, special-purpose non-residential build-
ings, or airplanes. This CO Alarm is specifically designed for
residential use, and may not provide adequate protection in
non-residential applications.

What Is Co?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
donotburncompletely,orareexposedtoheat(usuallyfire).Electrical
appliances typically do not produce CO.
These fuels include:Wood,coal,charcoal,oil,naturalgas,gasoline,
kerosene,andpropane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can
risequickly.COisarealdangernowthathomesaremoreenergy
efficient. “Air-tight” homes with added insulation, sealed windows, and
other weatherproofing can “trap” CO inside.
The following symptoms may be related to CARBON MONOXIDE
POISONING and should be discussed with ALL members of the
household:
Mild exposure: Headaches, running nose, sore eyes, often described
as“flu”-likesymptoms;
Medium exposure: Dizziness,drowsiness,vomiting;
Extreme Exposure: Unconsciousness, brain damage, death.

“ALARM-MOVE TO FRESH AIR”
If you hear the alarm horn and the Red light is flashing,
move everyone to a source of fresh air.
DO NOT disconnect the batteries from the CO Alarm!
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace,gaskitchenrangeorcooktop,gasclothesdryer.
Damaged or insufficient venting: corroded or disconnected water
heaterventpipe,leakingchimneypipeorflue,orcrackedheat
exchanger,blockedorcloggedchimneyopening.
Improper use of appliance/device: operating a barbecue grill or
vehicleinanenclosedarea(likeagarageorscreenedporch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
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 may not waken all individuals. If children or others do not
readilywakentothesoundoftheCOalarm,orifthereareinfantsor
familymemberswithmobilitylimitations,makesurethatsomeoneis
assigned to assist them in the event of an emergency.
CO Alarms will not work without power. This alarm requires one
standard 9 volt battery to operate.
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 Alarm with most
battery-powered 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 man-
ufacturer 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(3meters).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 poison-
ing. 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.

CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not pres-
ent.

affected. The average healthy adult might not feel any symptoms when
the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
canbemorequicklyandseverelyaffectedbyCO.Ifyouexperience
