Halo Smart Smoke Detector

My issue with mine got worse. First a smoke alarm and then a minute later it cleared and then carbon monoxide alarm and it would not go off so I had the fire department come out and they found zero carbon monoxide. So I replaced the detector with one of my spare ones. No alarms and all is fine. (oh and I also have another carbon monoxide attached to my alarm system and it did not go off).

So is the one I took down trash or any way to re calibrate the sensors?

Once they break they are done, I had the same problem had to replace with a spare
