First of all, it's "siren", not "cyrin".
Second, you're actually seeing the only set of ports. For some reason, a large number of these "flattened bird house" style Federal Signals had the core (the siren inside the housing) flipped upside down. I believe this was done in an attempt to increase sound output, being that the "smooshed" housing appears it would be restrictive. They are nothing more than normal Model 5's.
Oh the cyrin Is actually because I have someone in my contacts by that name And so my phone decides to “Correct” when in reality it’s more of a nuisance than anything
And wow I just learnt something new today, I didn’t actually think that they flipped them upside down, I thought they actually mounted it on top of an older Siren of some sort Or potentially they had two sirens, a Dual tone for civil defence and single tone for fire, in a similar way to how the Europeans do their sirens
, I apologise if I sound like a siren Kiddie But this is generally what I have found out plus combined with a assumption of knowledge, please do take my words with at least a water softener bag of salt
