Crossword Genius

Fire exit (2,3)

Ross

I believe the answer is:

go off

This clue is a double definition.

'fire' is the first definition.
(synonyms)

'exit' is the second definition.
(thesaurus)

(Other definitions for go off that I've seen before include "Rot; leave" , "Fire" , "Turn" , "Decay - become disenchanted with" , "Explode" .)

I've seen this clue in The Times and The Sunday Times.
