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. In addition, the optimised electronic compressor signal offers another possibility, to increase the attention of road users.

Variable urban/rural switching

Urban driving - Lateral spread

Particularly effective in critical crossing areas

Rural driving - Range & intensity

Acoustic road clearer

PRODUCT BENEFITS

funtioning in the system - via CiA447, FireCAN or analogue* controllable
one for all - special signals DIN URBAN/RURAL, international tones**, compressor, public address and radio activation as well as Airhorn/Bullhorn are available via a tone sequence amplifier
maintance-free - system consisting of electronics and loudspeaker require no maintenance
weather resistant - loudspeakers have been proven to be water resistant for years
energy efficient - ¼ of the power consumption in comparison to a conventional compressor system
reduced interior noise - no pumping compressor noise, which interfere with communication or stress the emergency personnel
simple assembly - due to the compact design and fewer components (e.g. no compressor or air hoses)

*AD- converter required

**YELP, WAIL, HILO, Netherlands, Austria. Further tone sequences on request.
