Combination Carbon Monoxide

Your recreation vehicle is equipped with a combination carbon monoxide (CO) / propane alarm that is listed for use in recreation vehicles. The combination carbon monoxide/pro-pane alarm will only work if it is operational and maintained. Refer to the manufacturer’s user guide for detailed safety and operating information.


  • Do not cover or obstruct the carbon monoxide/propane alarm with anything that could prevent gas from entering the alarm.
  • This alarm is not designed to detect smoke, fire, or gases other than carbon monoxide and propane.
  • The carbon monoxide detector installed is intended for use in ordinary indoor locations of recreation vehicles. It is not designed to comply with Occupational Safety and Health Administration (OSHA) commercial or industrial standards.
  • Do not disconnect the battery or the alarm.
  • Individuals with medical problems may consider using warning devices that provide audible and visual signals for carbon monoxide concentrations under 30 PPM.
  • This alarm will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas.
  • The ultimate responsibility for protection against toxic carbon monoxide fumes rests solely on you. Installing a carbon monoxide/propane alarm is just the first step in protecting your family from toxic carbon monoxide poisoning. The following symptoms are related to carbon monoxide poisoning and should be discussed with all members of the household:
  • Mild exposure: Slight headache, nausea, vomiting, fatigue (often described as “flu-like” symptoms).
  • Medium exposure: Severe throbbing headaches, drowsiness, confusion, and fast heart rate.
  • Extreme exposure: Unconsciousness, convulsions, cardio-respiratory failure, death.

The alarm is directly wired to the 12-volt electrical system, with continuous power being supplied by the recreational vehicle batteries. There is no 9-volt battery power supply. As a result, the alarm is always drawing a small amount of current from the recreation vehicle batteries. Although the current draw is slight, it could drain the batteries during extended storage periods. This condition is not likely to occur except during storage situations when the inverter cannot restore the battery charge. If the battery cable is disconnected at the battery terminals, the combination alarm will not work.Jayco Alante 2023 Secondary Means of Escape User Manual 04

Carbon monoxide (CO) is an insidious poison. It is a colorless, odorless, and tasteless gas. Many cases of reported carbon monoxide poisoning indicate while victims are aware they are not well, they become so disoriented they are unable to save themselves by either exiting the recreational vehicle or calling for assistance. Young children and household pets may be the first affected. Your combination carbon monoxide/propane alarm is designed to detect the toxic carbon monoxide fumes that result from incomplete combustion, such as those emitted from appliances, furnaces, fireplaces, and auto exhaust.

This alarm is designed to sense the presence of carbon monoxide/propane gas, however, there are other combustible fumes or vapors that may be detected by the sensor including (but not limited to): acetone, alcohol, butane, and gasoline. These chemicals can be found in commonly used items such as deodorants, colognes, perfumes, adhesives, lacquer, kerosene, glues, wine, liquor, most cleaning agents, and the propellants of aerosol cans. High temperatures can activate glue and adhesive vapors. If you close up a recreational vehicle on a hot day, the chemicals used in its construction may be detected for months after the vehicle was constructed (for more information, refer to Sec. 2, Formaldehyde).


  • Actuation of this detector indicates the presence of carbon monoxide which can kill you.
  • Never turn the 12-volt battery disconnect control to the off position and disconnect the battery cable to silence an alarm. The alarm will automatically sense when the level of carbon monoxide in the air reaches below dangerous levels. You should stay outside the vehicle in fresh air until the alarm is silenced. When the alarm sounds, do not stand too close to the alarm. The sound produced by the alarm is loud (85db) because it is designed to wake a person in an emergency. Prolonged exposure to the alarm at a close distance may be harmful to your hearing.
If the CO alarm sounds with a 4-chirp pattern:
  1. Immediately move to fresh air—outdoors or by an open door or window. Do a head count to check that all persons are accounted for. Do not re-enter the premises, or move away from the open door or window until the emergency services responder has arrived, the premises have been aired out, and your CO Alarm remains in its normal condition.
  2. Call your emergency services, fire department, or 911.
  3. After following steps 1-2, if the CO Alarm reactivates within a 24-hour period, repeat steps 1-2 and call a qualified appliance technician to investigate for sources of CO from fuel-burning equipment and appliances, and inspect for proper operation of this equipment. If problems are identified during this inspection have the equipment serviced immediately. Note any combustion equipment not inspected by the technician, and consult the manufacturers’ instructions, or contact the manufacturers directly, for more information about CO safety and this equipment. Make sure that motor vehicles are not, and have not, been operating in an attached garage or adjacent to the residence.

If the Propane alarm sounds with constant beeps:

  1. Immediately evacuate the from the RV.
  2. Shut off propane gas supply at propane tanks or supply.
  3. Do not touch any electrical switch in or near the RV
  4. Do not start the vehicle’s engine.
  5. Contact a qualified RV or gas technician for repairs.
  6. Do not turn on the gas supply unit the leak has been repaired.
