Custom 510 Hz Whelen WPS-2909 EPZ Siren Test - Ashford AL 12/11/24

[@SouthGeorgiaSirens]

The undertone on this one sounds awesome.... I heard a similar noise whenever I was directly beneath the unit on Fryer and Colquith during the 2022 test.

[@SirenArchives]

Sounds just like an 8-port DC-motor electromechanical siren (the tonality, not the wind-up/wind-down characteristics).

[@AmericanSirenProductions]

I like it more than 560

[@WJfilms]

This sounds like a Screamer S-2 or an S-5.

[@thunderlines-q4d]

Can you control the pitch using a potentiometer like the Siratone?

[@DJ2226]

No. Whelen produced a special firmware for this system to make them run like this.

@@DJ2226 Thanks for the info 👍
