Do all hard wired smoke detectors have batteries? Mine was chirping on and off and when I went up to open and see there was no battery. Is that normal?

If you don't have a user manual, use the manufacturer and model number. Go online and search their web site to see if/where the battery is. Also there may be a help line you can call.
All of ours do. Is there a spot for a battery but no battery in or just no place for a battery at all? If the battery slot is just empty, I would toss one in and see if the chirping stops.
It must have a battery "back-up" in case of power outage, battery needs changed.
