## Questions & Answers

**Q: What is the difference between the kn-cosm-xtra-b and kn-cosm-xtra-ba?**
A: The kn-cosm-xtr-b has not been made since 2012. The warranty was 5 years and it had a  7 year life. It took 3 AA batteries.
The kn-cosm-xtr-ba has a 10-year life and warranty. In addition, it uses 2 AA batteries and the battery compartment is now on the front.

**Q: 10 year warranty but co2 requires replacement in 7?**
A: prior to 2013 the sensor had a 7 year life, but that is now 10-years.

**Q: I can't get the battery door to open so that the batteries can be placed in. Any ideas on what to do?**
A: There are red "arms" in the battery compartment that get stuck on the lip of the door is closed without batteries installed. Use an implement to bend the arms back and then slide door open.

**Q: Is this okay to place in the kitchen?**
A: You do not need to place this near the floor. Carbon monoxide spreads evenly throughout a room. It doesn't "fall" as some have suggested. Although as everyone knows, smoke DOES rise, so the ceiling is a fine place to install for both dangers.
