Carbon monoxide is odourless, colourless, and kills people in their sleep. This combination alarm covers both smoke and CO in one unit, with a digital display showing the CO level in parts per million — so you know whether you're seeing a low-level problem or an emergency.
- Detects both smoke and carbon monoxide
- Digital display — shows CO concentration in ppm, not just an alarm
- Sound and light alarm — loud siren plus visual indicator
- Battery operated — works during a power cut, which is when CO risk is highest
- No hub or app needed — standalone protection
Where to fit CO alarms: outside every sleeping area and on every level of the home, including the basement. If you have gas appliances, an attached garage, a fireplace or a wood stove, this is not optional equipment.
Check your state and local code — several US states require CO alarms in all dwellings with fuel-burning appliances or attached garages.
