I've been dreaming of this day ever since I first heard this siren in person 2 years ago. Sure it sounds funny with the broken high tone damper, but now I've heard an in-service 4/5 Thunderbolt 1003 doing steady hi-lo and I was given permission to set it off. I even taught the fire chief something he didn't know, which is the ability to run custom signals via the RCM panels. A huge shoutout to @NebraskaSirenProduction as well as fire chief Mike Becker for making this test possible! Sadly the other enthusiast didn't get hi-lo on tape due to issues with his camera equipment so I sent him a copy of this video as a thanks for making this happen. So yes, he has my permission to post this. Anyone else caught reuploading this will be issued a copyright claim.
Since this was a special test, I growled it at first to let civilians know it will be tested a 2nd time. That also allowed me to find out that the test button on this siren's AF Timer is hooked up the way it should be, in the sense that the flasher and solenoids are tested when the test button is pressed, as it says in the manual. We could have held that button for a minute, but I decided it would be more fun to use the RCM panel switches instead since we could also get BTS footage of it going off in hi-lo from outside the building.
This should go without saying, but since I am aware of this siren being tampered with previously, DO NOT OPEN SIREN PANELS OR ADJUST SETTINGS WITHOUT PERMISSION! I was told by jcb19 at SirenCon 2023 that someone managed to sneak in and mess with the chopper level and time delay settings since the first time I heard this siren in person. As cool as it may seem to be able to alter a siren, let me tell you, it's not. It is called UNAUTHORIZED TAMPERING with a LIFE SAFETY SYSTEM and can lead to criminal charges. On the other hand, setting off a siren outside of test time when there's no emergency can constitute creating a false emergency which is a FELONY CRIME! This includes sirens that you own personally. It is no different than calling 911 with no emergency/prank calling them. We had permission from both the fire department and county dispatch to set off the siren after its usual test and knew what we were doing. We did not adjust the chopper level (frankly I love how Thunderbolts sound on level 7) or do anything other than setting it off manually.
