FABISENSE  3-in-1 Plug-in CO Detector with Backup Battery

Never compromise on safety. The FABISENSE 253-A combines a professional-grade electrochemical CO sensor with a 1000mAh backup battery, ensuring your home stays protected 24/7 — even during power outages. With 5-second rapid detection, a dual alert system, and one-touch self-calibration, it's the plug-in CO detector that's always ready when you need it most.

✅ Key Features

• Electrochemical CO Sensor: Professional-grade sensor delivers rapid 5-second detection with high accuracy. Far more reliable than standard semiconductor sensors for CO-specific detection.
• 3-in-1 Monitoring: Simultaneously tracks CO concentration, ambient temperature, and relative humidity — giving you a complete picture of your indoor air quality.
• Dual Alert System (≥85dB + Strobe): Loud audible alarm combined with a bright strobe light ensures you're alerted even if you're asleep or in another room.
• 1000mAh Backup Battery: Continues monitoring and alarming during power outages. No gaps in protection, no matter what.
• One-Touch Self-Calibration: Quick and easy calibration at the press of a button. No tools, no technician needed.
• Plug-and-Play Installation: Plugs into any standard 110–220V outlet. Clear digital display shows CO levels, temperature, and humidity at a glance.
• Wide Application: Ideal for bedrooms, living rooms, kitchens, garages, RVs, hotel rooms, and anywhere continuous CO monitoring is needed.

⚠️ Alarm Thresholds

• CO 0–50 ppm: Safe — normal operation, no alarm.
• CO 51–100 ppm: Warning — audible alert + strobe. Ventilate the area.
• CO 101–300 ppm: Danger — maximum alarm + strobe. Evacuate immediately.
• Power outage: Backup battery activates automatically. Monitoring continues uninterrupted.
