In for 4 to replace my old Firex and Kidde hardwired models with the 9V backup.

I chose these because:
- They cover both smoke and CO
- They use photoelectric sensors which should be more accurate
- They are networked
- They should be easier to silence false alarms because they announce which room is the culprit
- These Costco 2-packs INCLUDE the adapters to connect to my old Firex and Kidde installations
- The backup batteries aren't Lithium Ion, but at least they are cheap and accessible AAs
- This deal is significantly cheaper than anything else with comparable features

Do these work if mixed with regular wired smoke detectors. I'm thinking of just replacing one on each floor so I have CO detection.

Yes, that's what I do. I have the combo detector in the hallways and regular ones in the bedrooms.
