The electronic Tyfon® horn and amplifier system is a high-performance option on vehicles which has limited or no access to compressed air, such as Trams or Metros. It can also be used instead of pneumatic horns as the electronic Tyfon® is certified according to the latest version of the TSI LOC&PAS. Customizable signalling along with speech/PA functionality makes the electronic Tyfon® the preferable choice among several rolling stock manufacturers.
