When we built our house (3 years ago) the Inspector had me place them:
1 in every bedroom
1 near the kitchen, we have an open area livingroom/kitchen
1 in the basement
They all must be tied together, same circuit with the extra wire to signal them all to go off together, with battery backup. Didn't care which type of smoke detector they were.

Not necessary with newer ones, like Kidde's. Many have 10 year Lithium batteries now.Also, the detector needs to be changed either 5 or 7 years. Look in the instructions.
Write this date on the inside of the battery compartment. You are NEVER going to remember when they need to be changed.
When you change the battery, you'll see the date.

The average is 10 year life now. A lot of them are now coming with "Life Long Batteries" (the battery is supposed to last 10 years)... I will just stick to changing mine every 6 months.
I have one in every bedroom, 1 upstairs (its an open upstairs, no dividing walls), 1 in the kitchen, 1 in utility room. 1 in the living room/tv computer room.
I say overkill is something that cant be reached when it comes to these as well as CO2 detectors (we got 2 in our house).
How would the location of smoke/CO detectors (not to mention fire sprinklers) be affected by the location of ceiling fans?
