SPECIFIC SAFETY RULES
Do not grill or barbecue or burn charcoal indoors or in
your garage.
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.
Do not idle the car in a garage -- even if the garage door
is open to the outside. Fumes can build up very quickly
in the garage and living area of your home.
Do not use any gasoline-powered engines (mowers, weed
trimmers, snow blowers, chain saws, or small engines) in
your garage.
Never use a generator inside a home or garage, even if
your garage door or other doors and windows are open.
Using a generator indoors can KILL YOU IN MINUTES.
WARNING:
READ and UNDERSTAND all enclosed materials. Read
this manual in its entirety, and make sure you understand
what to do if your Carbon Monoxide Alarm sounds.
What levels of CO cause an alarm?
Underwriters Laboratories Inc. Standard UL 2034 requires
Carbon Monoxide 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).
This unit is designed not to alarm when exposed to a
constant level of 30 ppm for 30 days.This alarm has not
been investigated for carbon monoxide detection below
70 PPM.
WARNING:
Your Carbon Monoxide Alarm is designed to alarm before
there is an immediate life threat. Since you cannot see or
smell CO, never assume it is 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.
Underwriters Laboratories Inc. Standard for Safety of
Single and Multiple Station carbon monoxide alarms, UL
2034.
According to Underwriters Laboratories Inc. UL 2034,
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. Carbon
monoxide alarms are intended to alarm at carbon mon-
oxide levels below those that could cause a loss of ability
to react to the dangers of carbon monoxide exposure.
CAUTION:
This alarm will only indicate the presence of carbon mon-
oxide gas at the sensor in your garage. Carbon monoxide
gas may be present in other areas.
This Carbon Monoxide Alarm monitors the air at the sen-
sor and is designed to alarm before CO levels become
life threatening. This allows you valuable time to exit your
home and to correct the problem in your garage. This is
only possible if your Garage Carbon Monoxide Alarm is
installed and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity
Ranges:
Carbon Monoxide Alarms are 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).
Potential limitations of Carbon Monoxide Alarms:
WARNING:
This Carbon Monoxide Alarm is not intended for use
inside your house or other family living areas. It is not
designed to measure CO levels in compliance with Oc-
cupational Safety and Health Administration (OSHA)
commercial or industrial standards.
