- UL 2034 5th Edition Certified & CSFM Approved — Fully meets UL STD 2034 5th Edition, the latest mandatory US safety standard for residential carbon monoxide detector. Follows official NFPA installation guidelines to deliver reliable, code-compliant protection for households, rental homes and residential properties. It also complies with California fire safety certification requirements.
- LCD Digital Display + Graded Low Level CO Early Warning System — This carbon monoxide detector features a clear digital screen showing live CO readings starting at 20ppm, so you can gauge hazard severity at a glance, effectively protecting vulnerable groups including infants, the elderly, pregnant women and pets from chronic low-level CO poisoning risks. The co alarm delivers multi-stage alert system: 30ppm early warning for slow low-level buildup, a loud 85dB danger alarm, and 12-hour alarm memory to alert you of missed CO events when you return home.
- Dual Installation Modes | Tabletop & Wall Mount — No wiring or electrician needed for this co detector. Place directly on any flat surface for instant use, or wall-mount with the included full hardware kit. A built-in safety lock prevents forgotten AA battery installation — the cover won’t close without batteries inserted. It auto-powers on after a 100-second warm-up with zero extra setup.
- Ultra-Compact & Portable for Home & Travel — Measuring just 4.09" L × 2.89" H × 1.43" W, and only 4.37 oz, this lightweight CO detector works perfectly for everyday home use and on-the-go protection. Bring reliable CO safety to hotels, vacation rentals, Airbnb stays, RVs, cabins and more.
- One-Touch Hush & Simple Weekly Self-Test — The single Test/Hush button silences nuisance CO alarms (4 minutes), low-battery chirps (12 hours) and end-of-life alerts (48 hours), while uninterrupted CO monitoring remains active. Use the button for quick weekly self-tests to confirm proper operation.
- All-Source CO Detection for Full Home Coverage — Reliably detects carbon monoxide from every type of fuel-burning source, including gas furnaces, water heaters, fireplaces, car exhaust, clothes dryers and kitchen stoves. Perfect for placement in bedrooms, hallways, living rooms, basements and on every floor of your home.
