The burglar alarm system at Hove Train Station's Esso petrol station releases smoke when activated by an intruder.
Firefigters from both Hove and Preston Circus rushed to the scene shortly before 5am on Sunday morning (February 9).
Police arrived minutes later. It is unclear if anything was taken.
Anyone with information should call Sussex Police on 101.
