Kidde COBDL Carbon Monoxide Alarm W/ Digital Display, 10-Year Life, 2 AA Battery Portable CO Detector

Description

Protect building occupants from the silent threat of carbon monoxide with the Kidde COBDL Carbon Monoxide Alarm, a professional-grade CO detection solution from North America’s #1 home fire safety brand. Engineered for residential HVAC installations where fuel-burning appliances such as furnaces, boilers, water heaters, gas ranges, and fireplaces create potential CO exposure risks, this portable alarm delivers advanced electrochemical sensing technology in a compact, tabletop or wall-mount form factor.

The COBDL goes beyond standard CO detection by providing low-level CO alerts — warning occupants of dangerous carbon monoxide concentrations before they reach UL alarm thresholds. This early-warning capability is especially valuable for protecting vulnerable populations including children, elderly adults, and pets, who are more susceptible to the health effects of prolonged low-level CO exposure. HVAC contractors can recommend this alarm as a complementary safeguard alongside routine combustion appliance maintenance, flue inspection, and indoor air quality assessments.

Featuring an easy-to-read backlit LCD display with peak-level memory, the COBDL allows homeowners and service technicians to instantly verify current CO concentrations (in ppm) and review the highest CO level detected since the last reset — a valuable diagnostic tool when troubleshooting potential combustion appliance issues or venting problems. A smart light-sensing feature suppresses non-critical low-battery chirps at night, reducing nuisance alerts without compromising safety.

Powered by 2 AA batteries (included) with a 10-year limited warranty and end-of-life replacement notifications, this alarm meets the latest UL 2034 standard, NFPA 72, NFPA 101, FHA, HUD, and California State Fire Marshal (CSFM) requirements — making it suitable for new construction, retrofit installations, multi-family dwellings, and rental property compliance. The portable design allows placement on any level of the home near sleeping areas and fuel-burning HVAC equipment, per industry best practices.

Features:

• Advanced Electrochemical CO Sensor — Precision detection technology provides reliable carbon monoxide monitoring across the full UL 2034 response range: 70 ppm (60–240 min), 150 ppm (10–50 min), and 400 ppm (4–15 min).
• Low-Level CO Alert Technology — Industry-leading early warning system detects sub-alarm CO concentrations faster than standard detectors: ≤21 min at 70 ppm, ≤9 min at 150 ppm, and ≤4 min at 400 ppm — ideal for homes with gas furnaces, boilers, or attached garages.
• Backlit Digital LCD Display with Peak Level Memory — View real-time CO concentrations and peak readings at the press of a button, providing HVAC technicians with diagnostic data during combustion analysis and service calls.
• Multi-Color LED Status Indicators — Three-color LED system (green for normal operation, red for CO alarm, amber for faults and end-of-life) enables at-a-glance status verification for homeowners and service professionals.
• HUSH™ Silence Feature — Temporarily silences nuisance alarms, reducing false-alarm frustration during cooking or brief combustion events while maintaining safety protection.
• Smart Night Mode — Ambient light sensor suppresses non-critical low-battery chirps during nighttime hours without compromising emergency alarm functionality.
• 10-Year End-of-Life Notifications — Audible and visual reminders signal when sensor replacement is required, eliminating guesswork and ensuring continuous code-compliant protection.
• 85 dB Audible Alarm at 10 ft — Loud, attention-grabbing alarm ensures occupants are alerted throughout the home, meeting UL residential alarm requirements.
• Portable Wall-Mount or Tabletop Design — Flexible installation accommodates any level of the home, ideal for placement outside sleeping areas and near fuel-burning HVAC equipment per industry recommendations.
• Battery-Powered Operation — Operates on 2 AA batteries (included) for hardwire-free installation, simplifying retrofit applications and ensuring protection during power outages.
• Code Compliance — Meets UL 2034, NFPA 72, NFPA 101 (one- and two-family dwellings), FHA, HUD, and CSFM standards for residential carbon monoxide protection.

Applications:

• Residential homes with gas, oil, or propane furnaces and boilers
• Properties with gas water heaters, ranges, ovens, or clothes dryers
• Homes with attached garages, fireplaces, or wood-burning stoves
• Multi-family housing, rental properties, and vacation homes requiring code-compliant CO protection
• Supplementary protection for homes with newly installed or serviced combustion appliances
