Ken,
We've got (New Construction) one in every Bedroom, outside in the Hallway and on each floor, all interconnected. Battery Backup not required at this time. In addition a CO detector is required by the bedrooms somewhere and must be AC powered, w/digital display, and of the type that records the total accumulated exposure.
Paul,
You probably know this is coming, but What kind of rooms are fires likely to start in?
Bill
