Federal Signal 500-DHTT - Annual Siren Test - Calhan, CO (4/17/23)

Today Calhan conducted their annual test of their Federal Signal 500-DHTT. My main camera malfunctioned prior to the test, so I only had this camera recording (sorry for the lower quality).
I met up with SPCKennesaw for this year's test. This year the town didn't forget to sound the All Clear signal, unlike last year.
Special thanks to Calhan PD for letting us sound off the siren! (BTS video of that coming later).
Calhan's siren is tested during spring (April or May). This siren sounds three 1 minute blasts, followed by a steady 3 minute "All Clear" tone.
Enjoy!

It's been a great pleasure to meet up with you, and it was fun for both of us to sound it off too.

Around 1:36 it almost sounds like a reverse wired cyclone winding down to me.
