Here is the noon blasting going on at my house from today. The first very faint siren is the Model 2 used as a time signal for the nearby power plant. Next is my 220 volt Model 2T hooked up to a timer, running on 110 volts. Last is my 220 volt Model 5T running on 110 volts, with me manually turning it on and off. Enjoy!
