## Questions & Answers

**Q: Is this smoke detector os coming with battery?**
A: They advertise it as having a 10 year fixed unit battery, so you can't replace it without replacing the unit.  My experience of them so far is that you can expect no more than 3 years before the low battery starts and you have to replace.  With 7 years 'left' on it's replace by end date.
Selling a unit as 10 years when it is 3 is disingenuous and I will not be buying Fireangel again.

**Q: Can ceiling mount for earlier model be used? Mine was installed a few years ago, so I think new models are same size.old one is ST620**
A: I have the SI-610 and was told when I phoned up this new one would fit in  the same mount

**Q: Does this product detect carbon monoxide?**
A: No - it is a fire and smoke alarm designed to detect house fires.

**Q: Will this attach to the base of my existing  ST-620 without me having to remove that as well?**
A: This unit is compatible with an ST-620 base plate.
