The Siren Board

Came across this 2750 on YouTube. It does a short 5-6 second 400hz tone during this test video. I suspect this ones a very old HSS branded siren. They've been installing their own HSS branded Whelen Omnis around Europe. I have no idea what controller it uses but its most likely using its Analog ESC-864 controller. Anyways, wanted to post this here to shine light upon it and to find more information about this WPS-2750.
