Скачать или смотреть School Tornado Alert Siren System

Hi everyone, yep I'm still at SG, just in a sales role for a few years now. I do go out to the field once in a while. Thank you to all the subscribers who like these videos.
Here is my niece helping me complete the test of her school's internal tornado siren system. I custom designed this system for them because prior to this, there was no way to alert the school and they do not have a PA system. There are 12 sirens throughout the building including two exterior ones. The pull stations are Spectrum Series custom labeled for this application. The sirens are the Federal Signal SelecTone 300GC model with the "Slow Whoop" tone module. Because of the voltage drop they do fall out of sync, but it gets the point across.
