RV detector FAQ

How often should RV detectors be replaced?

Most RV propane and CO/LP detectors have a 5–7 year sensor life — check the date printed on the unit. An expired detector can still beep on test while the sensor itself is unreliable.

Where should each detector be mounted?

Propane detectors mount low (propane is heavier than air); carbon monoxide detectors mount higher. Dual CO/LP units follow the manufacturer's specified height.

My detector keeps beeping — do I need a new one?

Not always: low 12V battery voltage, dust, and aerosol fumes are common causes. Work through our beeping detector troubleshooting guide, and see the detector buyer's guide if it's time to replace.

Why does my RV propane detector keep beeping?

Low battery voltage, an expired sensor or real gas. Detectors have a service life, so an older unit that chirps often needs replacing. See RV propane detector keeps beeping.

Where should an RV propane detector be mounted?

Low on the wall, because propane is heavier than air. Carbon monoxide alarms go higher up, near the sleeping area. Follow the installation sheet for the exact height.

How often should RV detectors be replaced?

Check the date on the label: most propane and CO detectors are rated for a set number of years and many signal end of life with a chirp. Replace any unit past its date.
