## Questions & Answers

**Q: Anyone know how to turn it off as alarm keeps bleeping and error code says low battery. Only been on three days and as it is Saturday no support**
A: This a sealed battery alarm, you can not turn it off, it must be faulty, send it back to the seller.www.cutlershardware.com

**Q: Is the battery already active in the box or do you activate yourself once received?**
A: It's already there and you activate it by mounting on the backing plate.  When you slide the unit onto the backing plate, there is a little moulding on the backing plate that pushes a lever in a slot on the unit and starts the 10 years (or whatever it is). There was an instruction- I half recall- to halt the process, but can't actually remember.

**Q: Is it suitable for a campervan**
A: Yes according to the leaflet,suitable anywhere a boiler or log burner is etc

**Q: Is the detector kite marked?**
A: Hello, yes it is, to EN50291-1-2010 RegardsCutler's Home Store
