READ ENTIRE MANUAL BEFORE USING THIS ALARM
Your new Atwood Carbon Monoxide and Propane (CO/LP) alarms are sophisticated
instruments that has been carefully designed and tested to detect CO and LP build
up in a residential or recreation vehicle environment.
Carbon Monoxide (CO) and Liquefied Petroleum (LP or Propane) gases can cause
hazardous conditions when found in high concentrations. Both gases are known to
be found in recreational vehicles and the proper detection of these gases provides
a safe environment for the occupants of the vehicle.
CARBON MONOXIDE AWARENESS
The following are the symptoms of Carbon Monoxide poisoning and must be
discussed with all occupants of the vehicle.
1. Mild Exposure: Slight headache, nausea, vomiting, fatigue (“Flue like
symptoms).
2. Medium Exposure: Severe throbbing headache, drowsiness, confusion, fast
heart rate.
3. Extreme Exposure: Unconsciousness, convulsions, heart and lung failure,
brain damage, and death.
Many cases of reported CARBON MONOXIDE POISONING indicate that while
victims are aware they are not well, they become so disoriented they are unable to
save themselves by either exiting the building or calling for assistance. Young
children and house hold pets are typically the first affected. This device does not
provide warnings for all levels of CO. Individuals with certain medical conditions
may consider using a warning device that provides both audible and visual signals
for carbon monoxide concentrations below 30 ppm. Everyone is susceptible to the
danger of CO, but experts agree that unborn babies, small children, pregnant
women, senior citizens and people with heart or respiratory problems are at the
highest risk for serious injury or death.
If you experience ANY symptoms of CO poisoning, consult your physician.
Be aware that the following conditions can result in transient CO situations, such
as:
4
1. Excessive spillage or reverse venting of fuel burning appliances caused by:
•
Outdoor ambient conditions such as wind direction and/or velocity, including
high gusts of wind; heavy air in the vent pipes (cold/humid air with extended
periods between cycles).
•
Negative pressure differential resulting from the use of exhaust fans.
•
Simultaneous operation of several fuel burning appliances competing for
limited internal air.
•
Vent pipe connection vibrating loose from clothes dryers, furnaces, or water
heaters.
•
Obstructions in or unconventional vent pipe designs which amplify the
above situations.
2. Extended operation of un-vented fuel-burning devices (range, oven, fireplace,
etc.
3. Temperature inversions which can trap exhaust gasses near the ground.
4. Car idling in an open or closed attached garage, or near a home.
LIQUEFIED PETROLEUM GAS AWARENESS
LP gas is commonly called Propane and is sold commercially as a suitable fuel in
portable and permanent heating and cooking appliances.
It is important to detect LP gas due to its explosiveness at concentrated volumes.
The lowest explosive limit for LP concentration is 21,000 parts per million (ppm).
This detector was designed to alarm at 10% of this limit or 2100 ppm.
SAFETY ALERT SYMBOLS
Safety symbols alerting you to potential personal safety hazards,
Obey all safety messages following these symbols.

CAUTION
This alarm will only indicate the presence of gas at the sensor. Gases may be
present in other areas. Read this entire manual before using the alarm.
WARNING
Avoid possible injury or death
WARNING
Actuation of your CO alarm indicates the presence of carbon monoxide (CO)
which can KILL YOU.
WARNING
This product is intended for us in ordinary indoor locations of family living units. It is
not designed to measure compliance with Occupational Safety and Health
Administration (OSHA) commercial or in
dustrial standards.
CAUTION

1. Operate Reset/silence button;
1. Immediately move to fresh air-outdoors or by an open door/window. Do a head
count to check that all persons are accounted for: Do not reenter the premises
nor move away from the open door/window until the emergency services
responders arrive, the premises have been aired out, and your alarm returns to
its normal condition?
2. Call your local Emergency Services Number or 911
( )
Fill in your local Fire Department number here
3. After following steps 1-3, if your alarm reactivates within a 24 hour period,
repeat steps 1-3 and call a qualified appliance technician
( )
to investigate for sources of CO and LP from fuel burning equipment and
appliances, and inspect for proper operation of this equipment. If problems are
identified during this inspection, have equipment serviced immediately. Note
any combustion equipment not inspected by technician consult the
manufacturers Instructions, or contact the manufacturers directly, for more
information about CO and LP safety. Make sure that motor vehicles are not, or
have not been operating in an enclosed area or in close proximity of other
vehicles.
Note: two self adhesive emergency contact tables are provided. The user must
add telephone numbers for the local emergency service provider and for a
qualified service technician. User must place one label next to the alarm. The
other label must be placed near a source of fresh air where you plan to gather
in the event the alarm indicates carbon monoxide presence.

ALARM OPERATION
The alarm includes four LED indicators, an LP, CO and LPCO oscillating multi-tone
audible alarms, and one Test/Reset button that provide interaction and feed back
with your alarm. The indicators allow you to troubleshoot your alarm and to
determine the proper actions to take. The visual indicators are labeled Power, Fault,
Carbon Monoxide, and Propane.
The alarm operates in six separate modes that will be identified in this section.
Power Off Mode
This mode indicates that there is insufficient power provided to the alarm. The
indicators and button will not function in this mode. Sufficient power must be
provided to the alarm to exit this mode.
Normal Gas Detection Mode
This mode indicates that gas concentrations are continuously monitored. It also
indicates that gas concentrations are at safe levels. In this mode the Power
indicator will be lit, and all other indicators will not be active. The Test function for
the Test/Reset button will be active.
11
Alarm Active Mode
This mode indicates that one or more gas concentrations have achieved unsafe
levels. In this mode the Power indicator will be lit. In the case that the CO
concentration is unsafe the Carbon Monoxide indicator will be lit. In the case that
the LP concentration is unsafe the Propane indicator will be lit. In this mode the
audible indicator will signal an alarm, and the Reset function of the Test/Reset
button will be active. This mode will be exited automatically if the CO concentration
falls to a safe level for an extended period of time and LP concentrations falls below
500 ppm for greater than 10 seconds.
Alarm Test Mode
This mode indicates that the Test function of the Test/Reset button was imitated. In
this mode, all visual indicators will be lit, and the audible indicator will signal an
alarm. The test/Rest button will not function during this mode. This mode will be
exited automatically within 10 seconds.
Alarm Reset / Stabilization Mode
This mode indicates that the alarm is stabilizing for the first 3 minutes after powerup or the first 6 minutes after the Rest Function was initiated. In this mode the
Power indicator will be lit, and the reset alarm’s indicator will be flashing. The other
visual indicators, the audible indicator, and the Test/Reset button function will be
off. This mode will be exited if the previously inactive alarm is triggered. If gas
concentrations are still high after the 6 minutes, the previous alarm will reactivate.
Fault Mode
This mode indicates that a fault has been detected that compromises some alarm
function. If a fault is detected on only one of the sensors, the other sensor would
function normally. The table below lists the indicator actions and the corresponding
alarm status. This mode will be exited automatically when the fault is cleared.
If the fault persists, the alarm is not functioning properly and must be replaced to
ensure your safety in the area.
12
End of Life Mode
The Detector will operate in end-of-life mode after the Detector has been powered
for 7 years +/- 128 days. This represents the operating life of the sensors used to
detect CO and LP gas.
After 7 years, the sensors are no longer reliable and the Detector must be replaced.
Once end-of-life mode has been entered, it is permanent, even after a power out
cycle. If the reset/test button is pressed during end-of-life mode, the audible alarm
will be silenced for 48 hours before being automatically reactivated. The power
visual indicator will be on and the CO and/or LP visual indicators will be flashing.
The audible alarm will be sounding per table below.
Note: two self adhesive emergency contact labels are provided. The user must
add telephone numbers for the local emergency service provider and for a
qualified service technician. User must place one label next to the alarm. The
other label must be placed near a source of fresh air where you plan to gather in
the event the alarm indicates carbon monoxide presence.

IMPORTANT – If this alarm does not test properly return it immediately for
repair or replacement.
The visual indicators have two distinct functions: On and Flashing.
The “On” function is indicated by constant solid brightness of the LED. The
“Flashing” function is indicated by the LED blinking once every second.
The audible indicator has two distinct functions: Alarm and Fault.
In the “Alarm” function, the alarm will sound four “beeps” in 1 second followed by 5
seconds of silence. After 4 minutes of alarming, each silence will last for 1 minute.
In the “fault” function, the alarm will last for 1 minute. In the “Fault” function, the
alarm will sound a “chirp” once every 40 seconds until the fault is cleared.
INSTALLATION INSTRUCTIONS
