Your project can be done in twenty small steps.
Step #1 : Understand your smoke detector.
Will the smoke detector have a wire soldered to it that has a voltage that is less than 5 volts?

Step #2
You need to finish step #1 first. This takes time, solder, voltage meters, and wire.
Maybe a wire not wanted. A microphone can be placed near the alarm to sense the loud siren. and send a microphone signal to an Arduino analog input.

Step #3 : tomorrow

I am going to get going.
