ASC T-128 Full Alert Siren Test (12/07/21)

This is siren #9 of the Nine Mile Point Nuclear Generating Station system. There are 40 sirens in the system that surround the plant in Scriba NY. This particular siren can be found out the corner of NY-104 and Fred Hayes Blvd in Oswego NY. The system is tested (growl) on the first Tuesday of every month. In December and June, they do a full 3-minute test (alert). This was the December 2021 Test. I recorded this test on two different devices, this is the stationary one.
If you listen carefully to the beginning you can hear the siren lowering in pitch and volume. The siren returns to its normal pitch and volume after about 1 minute and 10 seconds. My guess is that the siren activated on battery power then switched to regular power. The siren batteries might also be faulty causing the wavering pitch and volume.

Nice video! Yeah I hear the pitch changing too! It was probably running on batteries at first which are probably the original ones from 2014 and should be replaced. The one I recorded sounded better. It was fun recording in the snow! 👍

Thank you! I definitely agree that the batteries need to be replaced. Recording in the snow was definitely an interesting experience.
