Drew's Federal Sign & Signal STH-10A | Alert | Kane County, Illinois

[@Midwest_Sirens]

For anyone wondering why it changed pitch is because I was messing with the speed on the VFD. Hopefully soon I'll get the VFD programmed to full 220VAC and it'll be able to go full power

[@dangerousnoodle3730]

Can't wait!!

[@Midwest_Sirens]

@@dangerousnoodle3730 yes sir, I'll tell you when it's all set up

[@davidwhitefancollector3985]

The pitch is very low & the wind up is very slow. Is to do with voltage?

[@Midwest_Sirens]

@@davidwhitefancollector3985 No, the slow wind up is due to the VFD and the low pitch is because I didnt crank the VFD up to full power

[@davidwhitefancollector3985]

What does VFD stand for?

[@BusMaster99]
