HEIMAN

The HEIMAN Wireless Interconnected Carbon Monoxide Detector comes in a convenient 3-pack, designed for battery-powered, portable use in homes, apartments, RVs, and travel scenarios. Certified to UL 2034 5th Edition and approved by the California State Fire Marshal, it targets renters, homeowners, and mobile users seeking reliable CO protection without permanent installation.

Standout features include the Japan-made FIGARO TGS5141 electrochemical sensor, which offers precise detection from 0-5000 ppm with stability against humidity and temperature fluctuations, minimizing false alarms compared to cheaper sensors. Wireless interconnection links up to 656 feet, sounding all alarms together, while custom grouping adds flexibility, even integrating with HEIMAN smoke detectors for comprehensive safety.

Build quality shines with a compact 2.76 x 2.76 x 1.46-inch mini design in flame-retardant PC+ABS housing, making it unobtrusive yet durable against heat and corrosion. The 10-year lithium battery and one-touch controls for testing, silencing, and low-battery muting ensure hassle-free operation.

Potential drawbacks include the need to pair units for interconnection and a non-replaceable battery, though its 10-year lifespan addresses long-term needs. No voice alerts mean reliance on the 85 dB siren and LEDs.
