7 sold in last 24 hours
UL 2034 5th Edition Certified & CSFM Approved — Meets strict UL 2034 5th Edition sensitivity and performance standards, and is CSFM approved for residential carbon monoxide alarm applications, compliant with NFPA installation codes.This CO alarm provides reliable protection for homes, rental properties and residential spaces. NOT for use in garages, workshops, or directly under vehicle mufflers/exhaust pipes. Operating temperature range: 40°F to 100°F (4.4°C to 37.8°C); performance will be compromised outside this range. 2 AA Battery Powered — NOT a Plug-In Alarm — This carbon monoxide detector operates on 2 replaceable AA batteries and does not plug into a wall outlet or require household wiring. Battery operation allows flexible placement without depending on a nearby electrical outlet. Replace batteries when the low-battery warning sounds; battery replacement is required during the service life of the alarm. Real-Time LCD Display + Graded Low Level CO Early Warning System — This carbon monoxide detector features a clear digital screen showing live CO readings starting at 20ppm (20–999ppm measuring range), so you can gauge hazard severity at a glance. 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. Tabletop or Wall-Mount Installation — 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.
