Can I replace just one smoke detector?
Yes, you can replace a non-wired smoke alarm with one that requires electrical power connection to the home wiring.

My old fire alarm only has two wires and my new one has three.
Will a hard wired smoke detector work without a battery?
Smoke Alarm Power Sources
