HEIMAN Smoke and Carbon Monoxide Detector Combo — 10-Year Sealed Battery, Photoelectric + CO Protection

HEIMAN’s 2-in-1 smoke and carbon monoxide detector delivers continuous dual-hazard monitoring with a sealed 10-year battery for maintenance-free safety.

Combining a photoelectric smoke sensor with carbon monoxide detection, this compact HEIMAN alarm is built to protect living spaces for a full decade without battery changes or hardwiring. Engineered to reduce false alerts and comply with current safety standards, it’s suitable for homes, rentals, and small commercial spaces where reliable, low-maintenance protection matters.

How does this unit detect both smoke and carbon monoxide?

The detector integrates a photoelectric smoke chamber to catch smoldering and fast-burning fires while a CO sensor monitors invisible, odorless carbon monoxide. Both sensors operate continuously and trigger a loud alarm when thresholds are crossed.

• Photoelectric dual-beam sensing for fast and smoldering fire detection
• Electrochemical CO sensing for accurate toxic gas alerts
• Independent circuitry to evaluate smoke and CO levels separately

What makes the 10-year sealed battery and housing special for homeowners?

This model ships with an internal lithium cell sized to last the device’s entire service life, eliminating annual battery swaps and late-night chirps. Its V-0 rated ABS+PC enclosure withstands high temperatures and resists corrosion, helping the alarm endure typical household conditions.

• Factory-installed 10-year lithium battery — no replacements needed
• UL94 V-0 rated casing for enhanced heat and flame resistance
• Designed to avoid common maintenance hassles and related costs

Does it meet safety standards and what certifications does it hold?

The device is tested to current U.S. safety benchmarks and carries multiple approvals to satisfy building owners and property managers. Those certifications indicate adherence to recognized test methods for both smoke and CO performance.

• Complies with UL 217 10th Edition for smoke alarms
• Meets UL 2034 5th Edition requirements for carbon monoxide detection
• CSFM-approved and produced with certified eco-friendly materials

How will I know if the alarm has detected a hazard or needs attention?

When smoke or CO reaches alarm levels the unit emits an 85 dB audio signal and a flashing LED for clear audio-visual notification. It also provides status feedback for low battery, faults, and the end of service life so you can maintain a functional protection plan.

• 85 dB siren plus flashing LED for immediate awareness
• 20-second alarm memory LED to indicate prior events when you return
• One-touch Test/Silence button for quick checks and nuisance-silencing

Who is this for? HEIMAN’s combo alarm is aimed at homeowners, landlords, contractors, and small-business operators who want dependable, low-maintenance hazard detection without hardwiring. It suits kitchens, bedrooms, living areas, rental units, and corridors where a long-life, certified smoke and CO solution reduces upkeep and increases confidence in daily safety.
