Eliminate the "invisible killer": Our 24/7 CO monitoring solution
Carbon monoxide (CO) is the "silent killer"—invisible, odourless, and deadly. Our Heiman CO Alarm is a premium 24/7 monitoring solution that goes beyond basic protection: blending cutting-edge technology with intuitive design, it safeguards your home against harmful CO leaks. Whether you’re asleep, at work, or away—we’ve got your home protected 24/7. -
Electrochemical Sensor: Precise CO Detection – Sleep Safe
Our Heiman CO Alarm features a high-sensitivity electrochemical CO sensor – the gold standard for CO detection. Engineered to respond exclusively to carbon monoxide, it triggers a precise alarm at levels as low as 50ppm, delivering zero sensor drift and no false alerts. As a indoor CO alarm, it detects hidden CO buildup even while you sleep, shielding you from the silent killer. -
Automatic Fault Detection: Distinct Alerts + Flexible Muting – Simplified Fault Resolution
It continuously monitors sensor and circuit status. In case of sensor failure or short circuit, the device immediately triggers clear alerts: the yellow LED flashes twice every 60 seconds, and the buzzer emits two beeps simultaneously—providing a clear fault indication to prevent hidden risks from being overlooked. -
Real-Time LCD Display: Visible CO Levels, Proactive Safety
Our Heiman CO Alarm features a crisp LCD display that shows real-time CO levels (in ppm) – so you don’t have to wait for an alarm to identify hazards. On a daily basis, it displays "0ppm" – your clear safe level indicator. Even minor CO increases (e.g., from poor kitchen ventilation or faulty heating) are shown early, letting you take proactive steps to avoid risks.
