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:

HOW CAN I PROTECT MY FAMILY?
A 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 CO Alarm is not a substitute for proper maintenance of home appliances.
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.
• 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 use grills or barbecue indoors, or in garages or on
screen porches.
• 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.
• 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.
UNDERWRITERS LABORATORIES INC. UL2034
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).
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 of CO, IT MUST ALARM BETWEEN
60 and 240 MINUTES.
* Approximately 10% COHb exposure at levels of 10% 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. UL tested for false
alarm resistance to Methane (500 ppm), Butane (300 ppm), Heptane (500 ppm),
Ethyl Acetate (200 ppm), Isopropyl Alcohol (200 ppm) and Carbon Dioxide (5000
ppm). Values measure gas and vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
GENERAL LIMITATIONS OF CO ALARMS
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 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.

HALL
orange interconnect wire.
3. Plug the power connector into the back of the CO Alarm.
BASEMENT
4. Position the base of the Alarm over the mounting bracket and turn. The
Alarm can be positioned over the bracket every 60°. Turn the unit clockwise
(right) until the unit is in place.
5. Check all connections.
USING THE OPTIONAL LOCKING FEATURES
The optional locking features are designed to prevent unauthorized removal of
the battery or alarm. It is not necessary to activate the locks in single-family
households where unauthorized battery or alarm removal is not a concern.
These CO Alarms have two separate locking features: one locks the battery
compartment, and the other locks the CO Alarm to the mounting bracket.
You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers • Standard Flathead screwdriver.
Both locking features use locking pins, molded into the mounting bracket. Using
needle nose pliers remove one or both pins, depending on which locking features
you use.
THE BATTERY COMPARTMENT LOCK
TO LOCK THE BATTERY COMPARTMENT:
Do not lock the battery compartment until you have
activated the battery and tested the battery back-up.
1. Activate the battery back-up by removing the "Pull to
Activate Battery Back-Up" tab. Push and hold the test
button on the CO Alarm's cover until you hear an
acknowledge chirp and the alarm sounds: 4 beeps,
pause, 4 beeps, pause.
If the unit does not alarm during testing, DO NOT
lock the battery compartment! Install a new battery
and test again. If it still does not alarm, replace the
CO Alarm immediately.
2. Using needle-nose pliers, detach one
locking pin from the mounting bracket.
3. Push the locking pin through the black
dot on the label on the back of the CO
Alarm.
TO UNLOCK THE
BATTERY COMPARTMENT:
Once the CO Alarm is installed, you must disconnect it from the AC power
before unlocking the battery compartment.
ELECTRICAL SHOCK HAZARD. Turn off the power to the area where the CO
Alarm is installed before removing it from the mounting bracket. Failure to
turn off the power first may result in serious electrical shock, injury or death.
Always discharge the branch circuit before servicing an AC or AC/DC CO
Alarm. First, turn off the AC power at the circuit breaker or fuse box. Next,
remove the battery from Alarms with battery back-up. Finally, press and
hold the test button for 5-10 seconds to discharge the branch circuit.
1. Remove the CO Alarm from the mounting bracket. If the unit is locked to
the bracket, see the section "To Deactivate the Locking Feature."
2. Disconnect the power connector by gently prying it away from the back of
the CO Alarm.
3. Insert a flathead screwdriver under the head of
the locking pin, and gently pry it out of the battery
compartment lock. (If you plan to relock the
battery compartment, save the locking pin.)
4. To relock the battery compartment, close the bat-
tery door and reinsert the locking pin in the lock.
5. Reconnect the power connector to the back of the CO Alarm, reattach the
CO Alarm to the mounting bracket, and restore the power.
When replacing the battery, always test the CO Alarm before relocking the
battery compartment.

INSTALLATION, continued
STAND ALONE ALARM ONLY:
•
If you are only installing one unit, restore power to the junction box.
INTERCONNECTED ALARMS ONLY:
•
If you are interconnecting multiple Alarms, repeat Step 1-5 for
each Alarm in the series. When you are finished, restore power
to the junction box.
ELECTRICAL SHOCK HAZARD. Do not restore power until all Alarms are
completely installed. Restoring power before installation is complete may
result in serious electrical shock, injury or death.
6. Make sure the CO Alarm is receiving AC power. Under normal operation,
the red indicator light will shine continuously. If the red power indicator light
does not light, TURN OFF POWER TO THE JUNCTION BOX and recheck
all connections. If all connections are correct and the red power indicator
still does not light when you restore the power, the unit should be replaced
immediately.
7.
ACTIVATING THE BATTERY BACK-UP
Activate the battery back-up by removing the "Pull to Activate Battery
Back-Up" tab. You do not need to open the battery compartment and
reposition the battery during installation. DO NOT remove the battery
activation tab until AC power is turned on to conserve battery power.
8. Test the CO Alarm. Press and hold the test button on the cover until the
alarm sounds: 4 beeps, pause, 4 beeps, pause. In a series of interconnected
Alarms, you must test each Alarm separately by pressing and holding the
test button. Make sure all units alarm when each one is tested.
If any unit in the series does not alarm during testing, TURN OFF POWER
and recheck connections. If it does not alarm when you restore power,
replace it immediately.
SPECIAL REQUIREMENTS FOR INTERCONNECTED CO ALARMS
• Failure to meet any of the above requirements could damage the
units and cause them to malfunction, removing your protection.
• AC and AC/DC CO Alarms can be interconnected. Under AC power,
all units will alarm when one senses CO. When power is interrupted,
only the AC/DC units in the series will continue to send and receive
signals. AC powered CO Alarms will not operate.
Interconnected units can provide earlier warning of a CO problem than stand-
alone units, especially if the problem starts in a remote area of the dwelling. If
any unit in the series senses CO, all units will alarm. To determine which CO
Alarm initiated an alarm, refer to the table.
On Initiating CO Alarm
Red LED Flashes Once per Second
On All Other CO Alarms
Red LED Does Not Flash Once per Second
Interconnect units within a single family residence only. Otherwise all house-
holds will experience unwanted alarms when you test any unit in the series.
