The newer TrueAlerts are so much louder than the older models, especially on code-3. I can stand continuous TrueAlerts however which is weird lol.

You mean the 4906 ones, including the conventional multi-candela 4906-9127? Yes, they are one of the loudest electronic horn/strobes out there, just as loud as the System Sensor SpectrAlert Advance and the Wheelock AS!
But they can’t beat the Simplex 4040 horns on Continuous at my old high school!
