Alli Archambault All of Whelens rotational sirens do that weird rotate one way and then stop, and then go the other way. That had to do that because if the siren did a full 360° turn, the wires inside the siren would snap and the siren would no longer work properly, let alone at all. Since they are electronic, unlike the other mechanical sirens. Such as the Thunderbolt.
This is rather peculiar. When Brandon filmed one doing Hi Lo, I thought it was just a malfunction since they normally run wail. This one also did the same thing the other one did, wind up and then cut in to Hi Lo
Elizabeth_958 Yeah And the weird thing is that the windup is the windup for Wail but then Another dtmf comes in for high low. The windup is because they called wail then Hi low. I have no Idea why.
