Alertus Technologies 600 Watt High Power Speaker Array

Alertus offers breakthrough text-to-speech technology embedded in a high power speaker array (HPSA) to overcome these challenges. Alertus can override your existing outdoor HPSA or design a new system to cover your campus, base, or facility outdoor areas with siren tones and clear voice messages. Alertus outdoor self-amplified high power speakers and low powered self-amplified speakers are also available should an HPSA not be suitable for your location.

Good speech quality and believable siren sound - I approve.

I noticed you guys have changed to a newer controller design. Are the new ones still capable of producing these “European” tones with the volume ramps? This sounds very similar to the sirens made by Telegrafia.
