3. Opsætning og installation
3.1 Valg af placering
For optimal performance, install the detector in areas where carbon monoxide or smoke may accumulate. This includes living rooms with stoves or wood fireplaces, kitchens, bedrooms, bathrooms, garages, cellars, and during travel in hotels or RVs. Ensure the device is placed where its display is easily visible and its alarm can be heard.
- For CO Detection: Place at breathing level, typically 1-1.5 meters (3-5 feet) from the floor.
- For Smoke Detection: Place higher on a wall or ceiling, away from air vents or fans that might interfere with smoke reaching the sensor.
- Avoid placing near windows, doors, or areas with high humidity or extreme temperatures.
