It's started going off intermittently. No, not batteries needing replacement chirping.
This is a rental, so I need to go through the rental agent - which I have done.
Turned the thermostat down to "keep things from freezing" and have cracked the door to get more fresh air. Seems to satisfy the alarm for now.
For what it's worth I've got an oxygen concentrator that hooks up to my CPAP. I can run a hose with a nasal anula from it to my recliner/computer.
So, hive, should I be calling the fire department as well?
stay safe.
