Hello.....my name is XXXXX XXXXX I will be happy to assist you with your electrical question. My goal is to exceed your expectations on Just Answer!

 

1) The yellow wire is used as the "inter-connected" wire. This yellow wire should be connected to other smokes that also have an inter-connected wire. The black wire is the hot wire, the white wire is the neutral.

 

2) There are a few reasons as to why a smoke detector will go into a chirping mode. One common reason is a loose white neutral wire connection or faulty splice.

 

Check out the following link from FireX and Kidde as to the causes of the chirping:

3) If your smokes are 10 years old or older, they also need to be replaced and have reached their end-of-life. All smoke manufacturers recommend replacing the smokes at a maximum of 10 years.

 



Hope this helps.........If you have any additional questions, let me know and I'll be glad to answer them for you.
