Federal Model 5TT Single Phase - Weekly Attack Test - Navarino, NY - CD Unit - 4/20/26

We were dying to see another Onondaga Civil Defense 5BT, so we decided to hit up Navarino, in the southern portion if the county, and it does a 5 cycle attack. Turns out it has a lot more pitch shifting than the last time it was recorded a couple years back, it also has a slight imbalance problem. Mason set uo the far angle out in a field pretty far behind the department, it was on an incline so the far shot was a pretty sweet level view of it. Despite lower pitch and shifting, it was surprisingly loud despite these things having a terrible rotor design. I will combine all the info here: It utilizes a 5-hp Northwestern branded single phase motor, installed around 1954, part of the Onondaga County Civil Defense system, mainly consisting of Thunderbolts and Model 5BTS, and us used as a fire siren. Testing is every day at noon including Sunday, and an attack on Mondays at 7pm with the Onondaga county fire dispatch. ________________________________________________ DO NOT USE WITHOUT PERMISSION #airraidsiren
