1 smoke detector not getting power

I have 1 of my interconnected smoke detectors that is not getting power. Green light is not on. I've confirmed the detector works and I have switched out the cable that comes with the new detector. All other detectors are operating properly. I've checked light switches and it does not seem to be wired to any (smoke detectors are on their own circuit). I'm not very experienced with this type of work. Any ideas?

If all your detectors are on the same circuit turn off power to the circuit. Then pull down the ones that are working and look at their wiring. Your detectors are probably daisy chained or series with the power for one coming off the one ahead of it in line. If a connection is bad the detectors upstream will have power but those downstream of the bad connection get no power.
