Voice Alarm

LEN-20

Varenummer: 1801-XXXXX

LEN-20 er en passiv 100 volt-højttaler, der er certificeret i henhold til EN 54-24 Type B til brug i talalarmsystemer. Som alle produkter i Voice Alarm-serien er den udstyret med et vejrbestandigt, stålforstærket aluminiumshus, hvilket gør den lige velegnet til indendørs og udendørs brug. LEN-højttalerne garanterer fremragende taleforståelighed og lang rækkevidde, selv i vanskelige akustiske omgivelser.

Main features

  • 2 × belagt 4" chassis
  • Jævn dækning og spredning
  • Undertrykkelse af uønskede side lobes takket være Fohhn Source Division Waveguide
  • Vejrbestandig uden yderligere beskyttelse (beskyttelsesgrad IP54 i henhold til IEC 529 / EN 60529)
  • 8 × M6 gevind til sikker montering
  • Fås i forskellige farver (RAL Classic, Pantone, NCS) eller med Fohhn Texture Design
  • For at sikre ydeevne og driftssikkerhed er Fohhn-systemforstærkere med den korrekte højttalerforindstilling påkrævet.
