Protect your RV and family with the Safe-T-Alert 45 Series dual-sensor alarm that detects both propane (LP) and carbon monoxide (CO) in a single, 12-volt hardwired unit. Designed for motorhomes, travel trailers, fifth wheels, and truck campers, the 45 Series provides fast, reliable alerts with loud audio and clear LED status. This black, flush-mount model is a clean upgrade from older single-gas alarms (e.g., 30/40-Series LP-only) and eliminates the need for separate CO detectors.

  • Dual protection: CO + LP in one device (fewer cutouts, cleaner install).
  • 12V DC hardwire, low draw: optimized for RV power systems; no batteries to forget.
  • Loud alarm + status LEDs: unmistakable alerts, easy diagnostics.
  • End-of-life indicator: lets you know when it’s time to replace (typ. 5–7 years; follow label).
  • Made for RV environments: vibration and temperature ranges suitable for mobile use.
  • Meets RV safety standards: listed to applicable CO and LP gas detection standards (UL/ANSI).
Best For: RVers who want one reliable, panel-mount alarm to continuously monitor both propane leaks and carbon monoxide without managing batteries or multiple devices.

Fit & Compatibility

  • Replaces older single-gas LP alarms (e.g., 30-/40-Series) when moving to dual-gas coverage.
  • Panel size: Black flush-mount fits common RV cutouts; verify your opening and bezel coverage before ordering.
  • Wiring: 12V DC hardwire. If upgrading from a battery-only CO alarm, provide fused 12V DC supply.

Install Tips

  1. Location matters: LP is heavier than air—mount low on a wall; do not mount in corners or near returns/vents.
  2. Hardwire to 12V: Observe polarity; use an inline fuse per the manual. Do not power from switched lighting circuits.
  3. Test monthly: Use the built-in Test function only; never use open flame/propane to “test.”
  4. Replace at EOL: When the alarm indicates end-of-life (or per label date), replace the whole unit.
Upgrade Path: If your RV currently uses a 40-442 (LP-only), the 45 Series gives you full CO + LP coverage in one opening. It’s the cleanest way to modernize safety without adding another device.

Common Questions

Will this replace my old LP-only alarm?
Yes. The 45 Series adds CO coverage as well. Verify your cutout and supply a fused, unswitched 12V DC feed.
Do I still need a separate CO alarm?
No—this unit detects both CO and LP. Some owners still carry a portable CO meter near sleeping areas for redundancy.
How often should I replace it?
Follow the replacement date on the label (commonly 5–7 years). The unit provides an end-of-life chirp/indicator when it’s due.
Where should it be mounted?
Low on an interior wall in the living space. Avoid corners, dead-air spots, floor registers, returns, and exterior doors.

Why Buy From RVupgrades

  • Real support: Phone, chat, email, and text—talk to people who actually know RV parts.
  • Fast fulfillment & tracking: Multiple warehouses, clear ETAs, and proactive order updates.
  • Flexible payment options: Choices you won’t get on marketplace sites.
Choosing between 30/40 vs 45 Series?
30/40 Series (LP Only)
Detects propane leaks only. Good if you already have a separate CO detector.
45 Series (Dual CO + LP)
One device, both gases. Clean upgrade for modern RV safety and fewer devices on your wall.
