CO alarm

Hi all, we also just bought a new Salem Hemisphere and so far we are enjoying getting it ready for our first camping trip.

But we have a problem with the C02 alarm, it is going off and don't know what to do. We have turned off gas, have tried the reset. Any ideas anyone. Would appreciate your advice. Thank you

A low battery will normally make the CO alarm chirp, make sure your battery voltage is above 12 volts.

If you have a house battery disconnect switch, turn it off and see if the beeping continues. If you can take off the negative cable for the battery, try that.

If disconnecting the battery works.... you either need to charge up or change that battery.
Happy Camping!

For the record: There is no CO2 (Carbon Dioxide) sensor. You have a smoke detector, a CO detector (carbon monoxide), and an LP gas sensor.

If your RV is new it may take a approximately 20-25 minutes of furnace run time to burn-off all the coatings before it stops setting off the CO and/or the smoke detector.

Discharged batteries in the smoke & CO detectors may also be a factor. Note: These devices only last for about 5 years from the date of manufacture which is tagged on the detector housings.

LP gas detectors are the same way. Keep in mind that chemicals are added to LP in order for you to smell an otherwise odorless/colorless gas. If you can smell propane, then you have a problem.
