The traditional signal used in many schools and sporting grounds
throughout Australia has been a range of electro-mechanical hooters
known as the “RVB” horn. Originally manufactured in Melbourne by the
RVB company the RVB horn produced a unique low resonating tone and
was often arranged in banks of several horns of different frequencies to
produce a particularly rich sound . This multiple combination was used
at all of the major Australian rules football grounds.
Even in its original form the RVB horn was a somewhat temperamental
device often requiring “retuning” after a few years of operation. However the
introduction of stringent EMC standards into Australia in the late 1990’s
required extensive modifications to the original product with a resulting
decline in reliability to the point where it was often necessary to return
horns to the factory for “retuning” after only a few months of service.
This situation was costly and frustrating for the end user, installer and
distributor. The Hootronic electronic horn from European Safety Systems
came to the rescue. With the ability to reproduce accurately the sound of
electro-mechanical devices the Hootronic now provides the reliability of an
electronic sounder.
As one installer put it…..

“The new E2S Hootronic sounder has proven to be a great success since its
Inception in January. Predominantly for use in schools & football clubs, it
replaces the old technology trumpet horn, which has been used for decades
due to its unique sound. Being in a Marine enclosure ( IP67), it is well suited
for both these outdoor applications. Its high impact casing, flexibility in
mounting & high DB rating will lend itself to reaching a much wider market
place in the future, Mining, general industry & monsoonal areas are a few
that spring to mind. Protective cages are readily available for areas where
vandalism is prevalent. Extremely good product well received in the market
place in such a short time frame.”
