Our hard-wire detectors all have 9 volt backup batteries. They'll chirp if the battery is dead or removed.
The dual sensor units are Ionization & Photoelectric in one. No CO sensor. I always kept a CO detector separate from Smoke detectors. I have a First Alert CO detector w/digital readout that plugs into the wall and has a battery backup.
