BASIC SAFETY INFORMATION
INSTALLATION
WHERE TO INSTALL THIS ALARM
•
Dangers, Warnings, and Cautions alert you to important operating
instructions or to potentially hazardous situations. Pay special
attention to these items.
For Gas Alarms, mounting depends on the type of explosive gas you intend
to detect.
Natural Gas (methane) is typically supplied through a main utility line
connected to your home. If you do not live in a rural area you are likely to
be a user of natural gas. Natural gas is a fossil fuel consisting mainly of
Methane. Methane is much lighter than air and will rise rapidly in air. If you
are a user of natural gas, the Alarm should be mounted between 6 and 12
inches (152mm and 305 mm) away from the ceiling (using cord feature) to
ensure the earliest opportunity to detect a leak.
•
This combination Explosive Gas/Carbon Monoxide Alarm has two
separate alarms. The CO Alarm is not designed to detect fire or any
other gas. It will only indicate the presence of carbon monoxide gas
at the sensor. Carbon monoxide gas may be present in other areas.
The Explosive Gas Alarm will only indicate the presence of explosive
gas that reaches the sensor. The Explosive Gas Alarm is not designed
to sense smoke, heat or flames.
Do not stand too close to the unit when the alarm is sounding. It is
loud to wake you in an emergency. Exposure to the horn at close
range may harm your hearing.
Propane is typically supplied to homes by delivery truck in liquid form and
stored near the home in propane tanks. Propane is used by homes in rural
areas that do not have natural gas service. Since propane is the most
commonly used Liquefied Petroleum Gas (LPG), propane and LP-Gas are
often used synonymously. Unlike natural gas, propane is heavier than air
and will collect at lower levels. If you are a user of propane, the Alarm
should be mounted near the floor (using the direct plug-in feature) to
ensure the earliest opportunity to detect a leak.
•
•
Do not paint over the unit. Paint may clog the openings to the sensing
chambers and prevent the unit from operating properly.
Both propane and natural gas are colorless and odorless. For safety
reasons, an ordorant (Mercaptan) is added so that any leak can be detect-
ed by smell. The common detection threshold for smelling the gases is
around 20% of the Lower Explosion Limit (LEL). This can vary greatly
depending on the individuals sense of smell and how long they have been
exposed to it. The LEL of each of these gases defines the bottom range of
flammability for the gas. Your Alarm is calibrated to sound before 25% of
the LEL of either gas detected.
•
This unit must be powered by a 24-hour circuit. Be sure the circuit
cannot be turned off by a switch, dimmer, or ground fault circuit
interrupter. Failure to connect this unit to a 24-hour circuit may
prevent it from providing constant protection.
This Alarm must have AC or battery power to operate. If AC power
fails and the battery is dead or missing, the alarm cannot operate.
The Alarm will check for the presence of explosive gas at the sensor
less frequently when powered by the back-up battery. Explosive gas
could be present during the period between checks without going
into alarm, especially during a condition that results in a rapid
buildup of explosive gas.
Test the Alarm once a week. If the Alarm ever fails to test correctly,
have it replaced immediately! If the Alarm is not working properly, it
cannot alert you to a problem.
•
•
Therefore, it is possible that you may smell gas before the Alarm is
activated. If you are not sure which gas your home uses, contact your
utility company.
For 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.
•
•
•
This combination Carbon Monoxide and Explosive Gas Alarm is
intended for residential use and is not suitable for use in hazardous
locations as defined in the National Electrical Code.
In general, install combination Explosive Gas and Carbon Monoxide
Alarms:
This product is intended for use in ordinary indoor locations of family
living units. It is not designed to measure CO levels in compliance with
Occupational Safety and Health Administration (OSHA) commercial or
industrial standards. Individuals with medical conditions that may
make them more sensitive to carbon monoxide may consider using
warning devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm. For additional information on
carbon monoxide and your medical condition contact your physician.
•
•
WHERE YOU CAN HEAR THE ALARM FROM ALL SLEEPING AREAS
In or near bedrooms and living areas or wherever you suspect a gas or
CO exposure is likely.
•
On each level of a multi-level home.
Improper location can affect the sensitive electronic components in this Alarm.

TEST THE ALARM
WHAT TO DO IF EXPLOSIVE GAS IS DETECTED
1. Make sure the Alarm is receiving AC power. Under normal operation, the Green
indicator light will shine continuously. If the Green power indicator light does
not light, recheck connections. If connections are correct and the Green
power indicator still does not light, the unit should be replaced immediately.
If you hear the alarm horn sound one beep per second, gas has
been detected. The word GAS will be displayed. Evacuate everyone
from the building.
2. Press and hold the test button until the alarm sounds. You will hear the
signal that indicates the presence of explosive gas followed by the signal
for carbon monoxide.
1. Leave the house immediately, opening doors and windows as you leave.
2. Do not use your telephone or appliances. Do not turn any light switches off
or on. Any spark or flame could ignite the gas.
3. Call 911 and your gas company from a phone that is away from your home.
4. Do not re-enter the area until the source of the leak is found and corrected.
When testing the Alarm, have someone else check that the Alarm can be
heard easily from the sleeping areas. The unit should be located where it
can wake you if it alarms at night.
• If the unit alarms and you are not testing the unit, it is warning you
of a potentially dangerous situation that requires your immediate
attention. NEVER ignore any alarm. Ignoring the alarm may result in
injury or death.

WHAT TO DO IF CARBON MONOXIDE IS DETECTED
WHEN THE CO ALARM IS SILENCED...
The CO Alarm will remain silent for up to 4 minutes. While the Alarm is
silenced, it will continue to monitor the air for CO. After 4 minutes, if CO levels
remain potentially dangerous the horn will start sounding again.
Actuation of your CO Alarm indicates the presence of carbon monoxide
(CO) which can kill you. In other words, when your CO Alarm sounds, you
must not ignore it!
The Silence Feature is intended to temporarily silence the Alarm horn. It will
not correct a CO or gas problem.
IF THE CO ALARM SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down the

SILENCING THE LOW BATTERY WARNING
This Silence Feature can temporarily quiet the low battery warning “chirp” for
up to 8 hours if AC power is present. You can silence the low battery warning
“chirp” two ways:
USING THE PEAK CO MEMORY
The CO Memory Feature lets you check the highest level of CO recorded.
To check CO Memory:
1. Press the Display button until the peak CO level is displayed.
1. Manually: Press the Test/Silence button on the Alarm cover until you see
To clear CO Memory:
the Green LED flicker, acknowledging the button-press.
1. While checking CO memory, press or hold the Display
button until “CLEAR” is displayed.
2. Using Your Remote Control: Standing no further than 12 feet (3.6 meters)
away from the Gas/CO Alarm, aim your IR remote at the Alarm and press
the CHANNEL or VOLUME button for at least 3-5 seconds.
2. Press or hold the Display button until the CO Memory is
cleared.
The display will flash “SILENCE” for 8 hours while the low battery warning
“chirp” silence feature is activated. After 8 hours, the low battery “chirp” will
resume. The Alarm will continue to operate as long as AC power is supplied.
However, replace the battery as soon as possible, to maintain protection in
event of a power outage.
NOTE: The highest CO level will be saved, even after a power interruption,
until you clear it. DO NOT clear the CO Memory reading if you plan to call
someone to investigate a CO problem! Clear the CO Memory reading only
after the investigator has checked your home.

SYMPTOMS OF CO POISONING
WEEKLY TESTING
These symptoms are related to CO POISONING and should be discussed with
ALL household members.
•
NEVER use an open flame of any kind to test this unit. You might
accidentally damage or set fire to the unit or to your home. The
built-in test switch accurately tests the unit’s operation as required
by Underwriters Laboratories, Inc. (UL). NEVER use vehicle exhaust!
Exhaust may cause permanent damage and voids your warranty.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung failure.
Exposure to Carbon Monoxide can cause brain damage, death.
•
DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing. When
testing, step away when horn starts sounding.
This Gas/CO Alarm measures exposure to CO over time. It alarms if CO levels
are extremely high in a short period of time, or if CO levels reach a certain
minimum over a long period of time. The Gas/CO Alarm generally sounds an
alarm before the onset of symptoms in average, healthy adults. Why is this
important? Because you need to be warned of a potential CO problem while
you can still react in time. In many reported cases of CO exposure, victims
may be aware that they are not feeling well, but become disoriented and
can no longer react well enough to exit the building or get help. Also, young
children and pets may be the first affected. The average healthy adult might
not feel any symptoms when the Gas/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 experi-
ence even mild symptoms of CO poisoning, consult your doctor immediately!
It is important to test this unit every week to make sure it is working
properly. You can test this Gas/CO Alarm two ways:
1. Manually: Press the Test/Silence button on the Alarm
cover until alarm sounds.
2. Remote Control: Aim your remote control at the Alarm
and press the CHANNEL or VOLUME button.
During testing, you will hear a loud, repeating horn pattern:
1 beep every second, while the Red LED flashes and the
display shows “GAS”. Then you will hear a loud, repeating
horn pattern: 4 beeps, pause, 4 beeps, pause, while the Red
LED flashes and the display shows “CO” with an increasing
CO ppm number.
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it difficult to
locate the source of CO after an alarm. These are a few of the factors that can
make it difficult to locate sources of CO:
If the Alarm does not test properly:
1. Make sure the AC power is applied and battery is fresh and installed
correctly.
2. Test the unit again.
If the Alarm is still not working properly, replace it immediately. Refer to the
“Limited Warranty” at the end of this manual.
•
•
•
House well ventilated before the investigator arrives.
Problem caused by “backdrafting.”
Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may be difficult
to locate the source of CO. BRK Brands, Inc. shall not be obligated to pay
for any carbon monoxide investigation or service call.
If there is still a problem, do not try to fix the Alarm yourself. This will
void your warranty!
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances
like: portable heater, gas or
wood burning fireplace, gas
kitchen range or cooktop,
gas clothes dryer.

screened porch).
Transient CO Problems: “transient” or on-again-off-again CO problems can
be caused by outdoor conditions and other special circumstances.
When the battery back-up becomes weak, the Alarm will “chirp” about
once a minute (the low battery warning). You should replace the battery
immediately to continue your protection. This Alarm must have AC or
battery power to operate. If AC power fails, and the battery is dead
or missing, the Alarm cannot operate.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by outdoor
conditions such as:
•
Wind direction and/or velocity, including high, gusty winds. Heavy air in
the vent pipes (cold/humid air with extended periods between cycles).
DO NOT spray cleaning chemicals or insect sprays directly on or near the
Alarm. DO NOT paint over the Alarm. Doing so may permanently damage the
Alarm.
•
•
Negative pressure differential resulting from the use of exhaust fans.
Several appliances running at the same time competing for limited fresh
air.
Vent pipe connections vibrating loose from clothes dryers, furnaces, or
water heaters.
Obstructions in or unconventional vent pipe designs which can amplify
the above situations.
CHOOSING A REPLACEMENT BATTERY:
•
•
Your Alarm requires one standard 9V alkaline battery. The following batteries
are acceptable as replacements: Duracell #MN1604, (Ultra) #MX1604;
Eveready (Energizer) #522. You may also use a Lithium battery like the Ultralife
U9VL-J for longer service life between battery changes. These batteries are
available at many local retail stores.
2. Extended operation of unvented fuel burning devices (range, oven, fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
Actual battery service life depends on the Alarm and the environment in which
it is installed. All the batteries specified above are acceptable replacement
batteries for this unit. Regardless of the manufacturer’s suggested battery life,
you MUST replace the battery immediately once the unit starts “chirping” (the
“low battery warning”).
These conditions are dangerous because they can trap exhaust in your home.
Since these conditions can come and go, they are also hard to recreate during
a CO investigation.
WHAT YOU NEED TO KNOW ABOUT CO
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 main-
tained, 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.

HOW CAN I PROTECT MY FAMILY FROM CO
POISONING?
REGULATORY INFORMATION FOR EXPLOSIVE GAS
ALARMS
A Gas/CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening for
average, healthy adults.
A Gas/CO Alarm is not a substitute for proper maintenance of home
appliances.
Standards: Underwriters Laboratories Inc. UL1484.
According to Underwriters Laboratories Inc. UL1484, this unit meets the alarm
response time for gas as follows: This unit shall alarm before 25% of the LEL
of either natural gas or propane is detected. In all cases, the unit will detect
gas as a priority over carbon monoxide. If the device is detecting CO, then
detects an amount of gas to cause an alarm, the device will stop alarming for
CO and begin to alarm for gas.
To help prevent CO problems and reduce the risk of CO poisoning:
•
Clean chimneys and flues yearly. Keep them free of debris, leaves, and
nests for proper air flow. Also, have a professional check for rust and
corrosion, cracks, or separations. These conditions can prevent proper
air movement and cause backdrafting. Never “cap” or cover a chimney
in any way that would block air flow.
GENERAL LIMITATIONS OF EXPLOSIVE GAS/CO
ALARMS
This Gas/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 Alarms must be met. This device is
not intended to alert hearing impaired residents.
•
•
Test and maintain all fuel-burning equipment annually. Many local gas or
oil companies and HVAC companies offer appliance inspections for a
nominal fee.
Make regular visual inspections of all fuel-burning appliances. Check
appliances for excessive rust and scaling. Also check the flame on the
burner and pilot lights. The flame should be blue. A yellow flame means
fuel is not being burned completely and CO may be present. Keep the
blower door on the furnace closed. Use vents or fans when they are
available on all fuel-burning appliances. Make sure appliances are
vented to the outside. Do not grill or barbecue indoors, or in garages
or on screen porches.
Gas/CO Alarms may not waken all individuals. If children or others do
not readily waken to the sound of the Gas/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.
This Gas/CO Alarm will not sense gas or CO that does not reach the
sensors. It will only sense gas or CO at the sensor. Gas or CO may be present
in other areas. Doors or other obstructions may affect the rate at which CO or
gas reaches the sensors.
•
Check for exhaust backflow from CO sources. Check the draft hood on
an operating furnace for a backdraft. Look for cracks on furnace heat
exchangers.
•
•
Check the house or garage on the other side of shared wall.
Gas/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
Gas/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 Gas/CO Alarm is not intended for people who are hearing
impaired.
Keep windows and doors open slightly. If you suspect that CO is
escaping into your home, open a window or a door. Opening windows
and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read this
manual in its entirety, and make sure you understand what to do if your
Gas/CO Alarm sounds.
REGULATORY INFORMATION FOR EXPLOSIVE
GAS/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO over
time (in minutes).
This Gas/CO Alarm is not a substitute for life insurance. Though this
Gas/CO Alarm warns against increasing CO levels or the presence of gas,
BRK Brands, Inc. does not warrant or imply in any way that they will protect
lives. Homeowners and renters must still insure their lives.
This Gas/CO Alarm is not foolproof. Like all other electronic devices, this
Gas/CO Alarm has limitations. It can only detect gas or CO that reaches the
sensors. It may not give early warning of the source of gas or CO is in a
remote part of the home, away from the alarm device.
This Gas/CO Alarm has a limited life. Although this Gas/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
this device weekly. The unit should be replaced immediately if it is not operating
properly.
UL2034 Required Alarm Points*:
•
•
•
If the alarm is exposed to 400 ppm of CO, IT MUST ALARM BETWEEN
4 and 15 MINUTES.
If the alarm is exposed to 150 ppm of CO, IT MUST ALARM BETWEEN
10 and 50 MINUTES.
If the alarm is exposed to 70 ppm if CO, IT MUST ALARM BETWEEN
60 and 240 MINUTES.
* Approximately 10% COHb exposure at levels of 15% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level of 30 ppm
for 30 days.
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 present.
•
An exposure to 100 ppm of CO for 20 minutes may not affect average,
healthy adults, but after 4 hours the same level may cause headaches.
•
An exposure to 400 ppm of CO may cause headaches in average, healthy
adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station carbon
monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2: “Carbon
monoxide alarms covered by these requirements are intended to respond to
the presence of carbon monoxide from sources such as, but not limited to,
exhaust from internal-combustion engines, abnormal operation of fuel-fired
appliances, and fireplaces. CO Alarms are intended to alarm at carbon
monoxide levels below those that could cause a loss of ability to react to the
dangers of Carbon Monoxide exposure.” This CO Alarm monitors the air at
the Alarm, and is designed to alarm before CO levels become life threatening.
This allows you precious time to leave the house and correct the problem.
This is only possible if Alarms are located, installed, and maintained as
described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The CO
Alarm is not formulated to detect CO levels below 30 ppm typically.
Audible Alarm: 85dB minimum at 10 feet (3 meters).
