Alright y’all. I’ve been trying to peice together the history of a siren system near me (Dublin, Oh), and I’m getting somewhere. However, I’m pretty bad in two areas of my siren journey. 1: FS 2001 models, and 2: Whelen controllers. In this video:

There are
A)560hz Whelen 27/8/9/05 running wail
B) Whelen 2750 with....... what?
I can say with 100% confidence that these are the older, original sound cards of the system, and they are whelens. And if anybody has info in Dublin, that’d be cool! Thanks.
Also, is this running on an older controller? Dublin has all 560 hz now, but is it a possibility they had the mystery controllers AND controllers that ran whatever hz this is?https://youtu.be/jEGMOPu28F0
