FIRESYSOK,
The Airbus A320 has a single smoke detector in the avionics bay. The pilot's nose being the second. If smoke not detected in flight deck by crew - don't action the checklist IMHO. It is one of the ECAM checklists that should not be actioned immediately but refer to QRH according to my airline.
Otherwise potentially you end up in a worse situation than necessary. Await the facts on this one though - not a pleasant experience I imagine.
