unlock the door when smoke detector...

[madie01]

i want to make a project to unlock the door when smoke detector detect any smoke at our place like our home..can u help me..in my idea:
-when smoke detector detect a smoke, it transmitted the signal 2 micro controller
-then micro controller transmit the signal 2 sub micro controller that control each floor..
-from sub micro controller, it will transmit the signal to unlock the door..

if we look, many people panic when there have a fire..so they doesn't find their key 2 unlock their home door..

can u help me..

Hello madie01,

I see too many potential failure points in your scheme...
Why not unlock doors by direct hardwired connection in event of smoke/fire detection?
