VILMA 55

ELECTROMECHANICAL CIVIL PROTECTION / AIR RAID WARNING SIRENS 

VILMA 55 Advantages

  • Designed and manufactured vertically in our premises in EU

  • Complying with PSEA norms of the Hellenic Civil Protection Ministry, as well as global norms

  • ISO 9001 certified

  • A robust and rugged electromechanical siren, with no sensitive electronic circuits

  • Very easy and quick installation

  • Produces a distinctive deep, loud, and clear 420 Hz sound of triangular waveform which can travel and be recognized many kilometers away

  • Very reliable with an extremely long lifecycle due to its simple structure and its rugged construction which makes the siren almost maintenance-free

  • Voltage fluctuations, lightnings, severe weather cannot affect VILMA55’s function and performance

  • Its vertical design with the special protective roof – resonator allows a 360ο sound propagation (omni-directional) covering very large areas

  • Ideal for densely populated cities where circulation noise and compact building can block sound propagation, as its sound can penetrate everywhere

  • One and only siren can cover large areas, whereas other siren types would demand more installations at the same cost per unit

  • VILMA 55 siren is covered by a long-term warranty
