The Siren Board

It's either a HPSA-3104 or a HPSA-81x4-R (x = 0, 1, or 2, depending on the age and radio). There isn't a way to tell unless you know what controller was on the siren originally. Since WAVES switched from SiRcom's horns to their own in around 2010-ish, this is a newer unit from Eaton or Cooper Notifications. If it is a 3100 series siren, it would have originally had a white fiberglass cabinet. The 7100/8100 series had an aluminum/stainless cabinet. The 7100 series was made to tie into a fire alarm panel, while the 3100 and 8100 series were radio-controlled, mostly using IP-based equipment or, in some cases, VHF/UHF-based stuff like most siren systems use.

It looks like a Hormann siren to me, but I'm not a expert myself so somebody needs to correct me.

I'm recording it on the first Wednesday of September, so maybe that will help further. Thank you for your reply!

Can you give me the video link please?

I'm very sorry, but I tried to record it but it didn't go off. I haven't been able to get any more info on it since then.

What's strange is I feel like I've seen photos of this exact setup floating around the internet with people claiming it's an "FS Thor", Federal Signal's diffraction horn siren. Did FS simply buy WAVES heads and sell them paired with their controllers, or is this not a Thor at all and we really have no pictures of them? Someone probably knows more about this than I do. I could be thinking of a totally different installation.

Cooper waves?
