The FEDHORN system is an electronic sirens system with horn sound.
HORN SOUND: Two synchronized sirens connected to two 100W speakers reproduce the sound of horn by electronic technology.
EASY INSTALLATION: Compact and modular system with an easy fitting into the vehicle, taking advantage of every space inside it.
EASY MAINTENANCE: Elimination of maintenance cost associated to oil compressor and air membranes systems due to use of a fully electronic system.
FLEXIBILITY: Specific configuration for different countries.

DAY/NIGHT: An internal sound damping assure a sound reduction during the night.
CANBUS: Communication System between lights, sirens and controller head. This system minimizes wiring installation and allows controlling all the elements by a single remote control.
