Frequently Asked Questions
Q: Does the smoke and CO combo detector come with a battery included?
A: No, the detector does not include a battery. It requires one CR123A (DC 3V) battery, which is sold separately. Once installed, the battery is designed to last up to 10 years under normal standby conditions.
Q: Where should I mount the smoke and CO detector — on the ceiling or wall?
A: This detector is designed for both ceiling and wall mounting. For optimal smoke detection, ceiling mounting is generally recommended. For CO detection, either position works well since CO disperses evenly throughout a room. Always follow your local fire safety guidelines for specific placement advice.
Q: How does the app notification feature work on this combo alarm?
A: The detector connects to a companion smartphone app and sends real-time push notifications when smoke or elevated CO levels are detected. This means you'll be alerted even if you're not in the same room — or even at home — giving you an extra layer of awareness and peace of mind.
Q: What safety certifications does this smoke and CO detector carry?
A: This detector is CE certified and complies with EN14604-2005 (smoke alarms) and EN50291-1:2018 (carbon monoxide alarms) European safety standards, ensuring it meets rigorous testing requirements for residential use.
Q: What is the coverage area of this combo detector?
A: The detector is rated for a coverage area of 20–40 m², making it suitable for average-sized bedrooms, living rooms, kitchens, and hallways.
