- White

Pros
- DUAL PROTECTION: This combination carbon monoxide (CO) and smoke detector offers vital protection against both CO and fire risks. The CO sensor alerts you to invisible gas dangers, and the optical smoke sensor quickly 'sees' slow, smouldering fires.
- 10 YEAR BATTERY: Each 2 in 1 carbon monoxide and smoke alarm for home use comes with a 10 year sealed battery that lasts the alarm's lifetime. When the device needs replacing, it will ‘chirp’ twice and the amber LED will flash twice every 40 seconds.
- ADVANCED DETECTION: The advanced optical sensing technology reduces nuisance smoke alarms by 'seeing' thick white smoke as it enters the alarm, while the advanced electrochemical CO sensing technology provides improved CO detection.
- DISTINCT ALARM SOUNDS: The dual smoke and carbon monoxide alarm features clear visual indicators and separate alerts for each hazard, allowing you to easily identify the specific danger when the alarm sounds
Cons
- No specific positioning guidelines for optimal installation.
- Warranty only covers part of the product lifespan.
