Fault lights on Co2 and Smoke Detectors
I have 3 smoke and 2 Co2 detectors. I just changed the batteries. Both of the Co2 detectors are now displaying the yellow Fault light, and two of the smoke detectors are displaying the Yellow test light with the red light blinking every ten seconds. I have no idea what the issue is. Any ideas?

It sounds like the CO and Smoke Detectors just aren't on their brackets all of the way. When the detectors aren't on all of the way, they will show those solid yellow lights and may also chirp once per minute. You can easily get the detectors back on the brackets properly by turning it further to the right until you hear it click into place. Once it does, the yellow light should turn off.
