Tone sequence system 724 & 744 Per4mance

During emergency drives the acoustic signal is often perceived too late by other road users. The reason for this is the one-dimensional sound propagation in tone sequence systems. With the TFA 7xx, Hänsch is breaking a new ground. In addition to optimised sound propagation for urban (wide pressure mode) and rural (direct pressure mode), the Adaptive Sound Pressure Technology (ASP) also offers an extension option with increased range and intensity: the TFA 744 Per4mance.

 

Variable urban/rural switching


Urban driving - Focus propagation

Valuable in critical intersections

 

 

 

 

 

 

 

 

 

Rural driving - Focus range & intensity

Acoustic road clearer                     

 

 

 

PRODUCT BENEFITS


  • CAN447 compliant – controllable via digital control units from Hänsch
  • variability of AF sources without additional switching box
  • power outputs for supplying analogue consumer loads without relays
  • flexibility due to configurability of load outputs by body manufacturer (no coding necessary)
  • public address via additional undercarriage loudspeakers (UKL) in the lightbar (optional)
