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.
8
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
9
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.

INSTALLATION INSTRUCTIONS
LP units when possible should be mounted to detect LP gas closer to the floor due to its heavier than air nature.
Select a location as close as possible to appliances that could be potential sources of LP gas leaks and where the initial concentration may be greatest. Do not install directly in front of air or furnace vents.
DO NOT INSTALL next to doors or windows that may dilute the
concentration of any LP gas presents in the environment and preclude a timely alarm signal.
DO NOT INSTALL the detector in a closet or in a location that could
become obstructed by a curtain, hanging clothes or any other objects.
DO NOT LOCATE detector where it could be exposed to splashes of
water or grease or where it could be damaged by impact with moving objects (i.e. furniture, feet, etc.).
DO NOT INSTALL on a wall switch controlled by a power line or
11
ground fault circuit.
Usually you will find more than one suitable location that will also provide ease of viewing and connection to power.
Never use detergents or solvents to clean the alarm, chemicals can permanently damage or temporarily contaminate the sensor.
Avoid spraying air freshener, hair spray, paint or other aerosols near the alarm.
The following is a list of substances that at high levels can affect the sensor and cause an alarm.
Methane, propane, iso-butane, ethylene, ethanol, alcohol, carbon monoxide, iso-propylene, benzene, toluene, ethyl acetate, hydrogen, hydrogen sulfide, sulfur dioxides.
Alarm Location for Minimum Protection

WIRING
Before routing the wires, disconnect the 12 VDC power supply to avoid shorting. Make sure that the power connections are made to a properly fused circuit (15 amp maximum) 1 amp fuse is recommended for single or multiple detector installation. Can be fused through a distribution panel or power supply box.
Connection to a Master Storage Switch is acceptable. The alarm will be off along with all other 12 volt equipment when the storage switch is turned to the off position. DO NOT USE THE RV WHEN THE
STORAGE SWITCH IS IN THE OFF POSITION.
All connections must be in accordance with the National Electrical
Code in the United States and the Canadian Electric Code in Canada.
All connections must use approved wiring and connectors of an appropriate size see wiring diagram label. Provide a minimum of 8 square inches to make wiring connection for DC models.
Some models are hard wired with a 110 AC adapter allowing the unit to be plugged directly into a 110 AC wall outlet.
13
FLUSH MOUNTING
A detachable mounting bracket allows the unit to be mounted as a flush installation supplied with the unit.
Mounting brackets attached to the surface where the alarm is to be mounted with four screws, see instructions below.
To install the mounting bracket to the alarm place the alarm inside the bracket and snap in place see diagram. To remove flush mounting bracket pull legs away from body of detector.
1. Verify that there is a minimum of (C)1-
1/2” inches of free space behind the wall.
2. Mark on the desired mounting surface a box approximately (A) 2-5/8
” inch wide by (B) 3-5/8
” high and cutout.
3. Route power leads to the opening and connect wire to the detector per the wiring diagrams.
4. Install the detector and excess wiring through the opening until mounting flange is flush to the wall.
14
Mount the unit using the 4 screws provided one in each corner of the flange.
SURFACE MOUNTING
1. Mark on the desired mounting surface a box approximately 2-1/2
” inch wide by 3-3/8
” high and draw an X corner to corner to find center and cut a 1” inch hole.
2. Route power leads to the opening and connect wires to the detector per the wiring diagrams.
3. Center and mount the base over the outline done in step 1 with the two screws provided through the two holes in the mounting base.
4. Slip the unit on to the mount tabs of the base and pull down into place.
AC Power Adapter Mounting
Power supply can be plugged into a 120 VAC wall outlet either on the surface or behind a wall in a cabinet if so desired.
1. Cut a hole in the wall large enough to slide the adapter through to the
15
outlet. Slide the adapter through the mounting box before screwing the box onto the wall.
2. Follow the steps outlined above for either surface or flush mounting of the alarm.
3. Adapter wire is run underneath the mounting bracket when installing a flush mounted alarm.
OPERATING INSTRUCTIONS
Applying power to the detector will cause the LED to flash red for 3 minutes and then turn green. Once LED is green, detector is monitoring for LP gas.
DETECTOR TEST
1.
Press “TEST” button until alarm sounds; then release the “TEST” button.
2. The detector will sound twice.
3. The LED will turn red, and then return to normal operation and turn green after 8 seconds.
4. This test must be carried out not less than once per week to ensure proper operation of the detector.
Lp Gas Detection
At <25% LEL concentration of LP gas the detector will provide a visual and audible alarm by sounding the buzzer and turning the LED Red. The buzzer may be temporarily silenced by pressing the Test/Reset button.
However, until the measured concentration is reduced to a safe level, the alarm will sound again within 3 minutes.
POWER MANAGEMENT
The operating voltage for the detector is 12 VDC. In these conditions, the unit will meet the specifications of the UL 1484 standard. The actual
16
voltage applied to the detector in a recreational vehicle may drop below the minimum 8 VDC. The Atwood Detector is designed to provide the user with a Low Voltage Warning before reaching that level and to provide additional distinct, clear warnings and alarms after the 8 VDC level is reached.
However, if available power supplied to the unit is below the operating voltage of 8 VDC, the detectors will not detect gas or provide you protection against dangerous levels of LP.
The following descriptions of operational modes will provide the user with an understanding of how the detector performs to conserve available battery power and alert the user to non-operating conditions to reduce to battery draw-down.
Power Failure
If no power is applied to the unit or there is a failure of power circuits, there will be no identification from the LED. If there is no indication from the LED, but the audible alarm sounds when the TEST button is pressed, then the
LED is defective and the user must contact the Atwood Service Center.
WARNING
Actuation of end of life of alarm indicates the alarm is nonfunctioning and will not detect the presence of LP gases which can KILL YOU.
END OF LIFE
Unit is designed to give maximum life of sensors under normal conditions.
This is seven years from date of installation of unit. A sticker has been provided to record this information and should be placed next to the unit were it can be viewed. At the end of life the unit will chirps every 30 seconds and the LED’s will flash Yellow. This state will continue until unit is
17
replaced. If the reset/test button is pressed during end-of-life mode, the audible alarm will be silenced for 12 hours before being reactivated. The
LED will remain flashing Yellow while the audible alarm is silenced for this period, at the end of the 12 hours the audible alarm will be turned on and the alarm will remain on and can’t be silenced. The alarm in this condition will not sense LP gas. YOU MUST REPLACE ALARM it is not field repairable.
