HO
W CAN I PROTECT MY FAMILY FROM CO
POISONING?
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
a
verage, healthy adults.
A
Gas/CO Alarm is not a substitute for proper maintenance of home
appl
iances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris, leaves, and
ne
sts 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
i
n 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
nom
inal 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
f
uel 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
v
ented to the outside. Do not grill or barbecue indoors, or in garages
or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft hood on
a
n operating furnace for a backdraft. Look for cracks on furnace heat
e
xchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO is
e
scaping into your home, open a window or a door. Opening windows
a
nd 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/C
O Alarm sounds.

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).
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 MUSTALARM BETWEEN
10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUSTALARM 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
ad
u
lts after 35 minutes, but can cause death after 2 hours.

erwriters 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
d
a
ngers 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.

According to Underwriters Laboratories Inc. UL1484, this unit meets the alarm
r
esponse time for gas as follows: This unit shall alarm before 25% of the LEL
o
f 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
d
etects an amount of gas to cause an alarm, the device will stop alarming for
C
O and begin to alarm for gas.
GENERAL LIMITATIONS OF EXPLOSIVE GAS/CO
ALARM
S
T
his Gas/CO Alarm is intended for residential use. It is not intended for use in
i
ndustrial applications where Occupational Safety and Health Administration
(OSHA) requirements for Carbon Monoxide Alarms must be met.This device is
no
t intended to alert hearing impaired residents.
Gas/C
O Alarms may not waken all individuals.
I
f 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
t
o assist them in the event of an emergency.
T
his 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 r
eaches the sensors.
Gas/C
O Alarms may not be heard.
T
he alarm horn loudness meets or
exceeds current UL standards of 85 dB at 10 feet (3 meters). However, if the
Gas/C
O Alarm is installed outside the bedroom, it may not wake up a sound
sle
eper 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
b
locked by distance or closed doors. Noise from traffic, stereo, radio, television,
a
ir conditioner, or other appliances may also prevent alert persons from hearing
the alarm horn.Th
is Gas/CO Alarm is not intended for people who are hearing
impa
ired.
This Gas/CO Alarm is not a substitute for life insurance. Though this
Gas/C
O 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.
