READ ENTIRE MANUAL BEFORE USING THIS ALARM
Your new Atwood Propane (LP) alarm is a sophisticated instrument that
has been carefully designed and tested to detect LP build up in a
residential or recreation vehicle environment.
Liquefied Petroleum (LP or Propane) gas can cause hazardous conditions
when found in high concentrations. Gas is known to be found in
recreational vehicles and the proper detection of this gas provides a safe
environment for the occupants of the vehicle.
THIS ALARM HAS A SEVEN YEAR LIFE, SEE END OF LIFE
NOTIFICATION
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. This detector is design to alarm at <25% LEL (legal explosive
limit).
SAFETY ALERT SYMBOLS
Safety symbols alerting you to potential personal safety hazards,
Obey all safety messages following these symbols.
WARNING
Avoid possible injury or death
CAUTION
Avoid possible injury and/or property
damage

4
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.
ACTIVE ALARM PROCEDURES
IF ALARM SIGNAL SOUNDS:
1. Operate Test/Reset 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 re-enter
the premises 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.

technician consult the manufacturer’s Instructions, or contact the
manufacturers directly, for more information about LP safety. Make

5
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 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
propane is presence.

ALARM OPERATION
The alarm includes an LED indicator, an audible alarm, and one Test/Reset
button provide interaction and feedback with your alarm and allow you to
troubleshoot your alarm and to determine the proper actions to take. The
alarm operates in seven 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 LED and button will not function in this mode. Sufficient power must be
provided to the alarm to exit this mode.
Normal Stand-by Mode
This mode indicates that a gas concentration is continuously monitored. It
also indicates that a gas concentration is at a safe level. In this mode the
LED indicator will be Green. The Test function for the Test/Reset button will
be active.

9
Alarm Mode
This mode indicates that a gas concentration has achieved unsafe levels.
In this mode the LED will be Red. 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 when LP concentrations fall below 500
ppm for greater than 10 seconds.
Test Mode
This mode indicates that the Test function of the Test/Reset button was
initiated. In this mode, the LED will be Red, 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.
Silence / Stabilization Mode
This mode indicates that the alarm is stabilizing for the first 3 minutes after
power-up or after the Reset Function was initiated. In this mode the LED
will be flashing Red. The audible and the Test/Reset button function will be
off. This mode will be exited after 3 minutes. If gas concentrations are still
high after the 3 minutes, the previous alarm will reactivate.
Fault Mode
This mode indicates that a fault has been detected that compromises the
alarm function. 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. During this mode, the LED will
be Yellow and the audible alarm will chirp every 30 seconds.
End of Life Mode

10
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
sensor used to detect LP gas. After 7 years, the sensor is 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 12 hours before being automatically reactivated. The LED
will be flashing Yellow. The audible alarm will chirp every 30 seconds.
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 propane is present.
