Caratteristiche principali

Il LEN-220 è un diffusore passivo a 100 volt con sorgente di linea certificato secondo la norma EN 54-24 Tipo B per l'uso in sistemi di allarme vocale. Come tutti i prodotti della serie Voice Alarm, è dotato di un alloggiamento in alluminio rinforzato in acciaio, resistente alle intemperie, che lo rende ugualmente adatto all'uso in ambienti interni ed esterni. Gli altoparlanti a colonna LEN garantiscono un'eccellente intelligibilità del parlato e una lunga portata anche in ambienti acustici difficili.

  • 18 × rivestito Telaio da 4"
  • Direzionalità uniforme
  • Soppressione dei lobi laterali indesiderati grazie a Fohhn Source Division Waveguide
  • Resistente alle intemperie senza protezione aggiuntiva (grado di protezione IP65 secondo IEC 529 / EN 60529)
  • Nuovo: Montaggio flessibile grazie alla scanalatura a T sul retro
  • Disponibile in diversi colori (RAL Classic, Pantone, NCS) o con Fohhn Texture Design
  • Per garantire prestazioni ottimali e affidabilità operativa, è necessario che gli amplificatori del sistema Fohhn includano la corretta preimpostazione dei diffusori.
