## Questions & Answers

**Q: Does the quick connect electrical connector come with each detector**
A: For all those writing reviews that they are unhappy with the AC plug in this is an easy fix.  First turn the power off to your smoke detectors.  If you don't know what breaker this is then just turn off the power to the whole house if possible and work with a small flashlight or head lamp.  Just disconnect the wire nuts from the existing electrical connector making sure to remember or mark which colors are connected to each other.  Then reconnect in reverse the new electrical connector and presto you have converted your current connections to the new electrical connector.  I did this on over 10 detectors two years ago and have 4 more to replace this winter.  It takes a little time, but is as simple as changing a light bulb.  Skill level is about a 1.

**Q: I bought the set of 4 and I need another why can’t I find single units of these on Amazon.**
A: Probably because if the connectors aren't the same, you can't return the product, so you get stuck with 4 boat anchors and they make bigger profits at your expense.  The product page does NOT say that there is no return.

**Q: Does test also sense for Carbon monoxide?**
A: No. There ARE combination smoke detectors/carbon monoxide detectors, but this isn't one of them.

**Q: What is the current date stamped on back of these detectors?**
A: 2021
