## Questions & Answers

**Q: Does this meet the Scottish 2022 updated legislation as I notice it has three batteries rather than built in?**
A: No, this does not meet the new Scottish legislation as these have replaceable batteries. You need to have a carbon monoxide alarmed with a sealed-in battery and we would suggest you purchase either the Kidde 10LLCO alarm or the Kidde 10LLDCO alarm which both have sealed-in battery and will last for the duration of the alarm. The battery is also covered as part of the 10 year warranty which is valid from the date of purchase.

**Q: What is the decibel rating for the alarm please?**
A: 85 decibels and this is also stated in the instruction manual

**Q: Hi , is this alarm comply with Bs 50291 ? Thanks**
A: Hi the answer is Yes it stamped BS50291 so it seems to comply

**Q: Does this unit comply with bs en 50291 standard?**
A: As per advert on Google for this unit it states - Kitemarked to BS EN 50291-1:2010 and CE marked, 7 year warranty.
