It would really be helpful if you could explain the (hardware) setting 
in more detail.
When you say "Python to listen" I assume you mean a microphone connected 
to a computer where your python programme will be running.

How many smoke allarms and in what radius should be detected? Or is it 
only a specific one?

This could range from a simple programme triggered by an amplitude 
change (e.g. a piezo attached to the single alarm in question) to a 
complex audio fingerprinting one...
