RV Safe Combo CO/LP Alarm | RVCOLP-2B | 2-Wire | Black

Protect your RV from two of the most dangerous gas hazards — carbon monoxide and propane — with the RV Safe RVCOLP-2B Combo CO/LP Alarm (2-Wire, Black). Designed and tested specifically for the rugged RV environment, ETL listed, and engineered to alert occupants quickly and accurately with fewer false alarms than competing detectors.

Dual Gas Detection — CO + Propane

• Carbon Monoxide detection using advanced electrochemical CO sensor
• Propane gas detection at 4,200 ppm (<20% LEL)
• Highly selective CO sensor — fewer false alarms from non-threatening chemicals and gases

Distinct Alarm Patterns for CO vs Propane

• CO gas detected: Four-beep pattern with flashing red LED
• Propane gas detected: Continuous beeping with solid red LED
• Both gases present: Alarm indicates propane (requires more immediate action)

Different alarm signals mean you know immediately which threat you're dealing with — meaningful for the correct emergency response.

Meets UL Standards

• UL 2034 — Carbon monoxide alarms in recreational vehicles
• UL 1484 — Propane gas alarms in recreational vehicles
• Listings: ETL, cETL, CSA 6.19

Test / Silence Button

Easy testing of the alarm plus quick silence for nuisance alarms.

Low Power Draw = Longer Battery Life

Uses low-power propane gas detection technology — increased RV battery life vs competing alarms. Only 17 mA at 13.5V DC.

⚠️ Verify You Need a 2-Wire Alarm

The RVCOLP-2B is the 2-wire variant — the most commonly installed configuration:

• 2-Wire: (1) red wire + (1) black wire — connected to positive and negative 12V leads. Most common.
• 3-Wire: (2) red wires + (1) black wire. Commonly found in Thor Industries-built RVs and trailers.

Check your existing alarm's wiring configuration before ordering.

Suitable for Replacing

• Safe-T-Alert 20, 25, 30, 35, 40, 45, 65 series
• Most Atwood and Dometic-branded CO/Propane alarms
