Most sirens will get that way eventually. It’s normal.

I would assume that was to prevent any bees or birds nesting under the siren

Agreed

Sounds like both are to me.

@@ArxCyberwolfPC Just the top one, the lower tone is still loud and strong

There the same port ratio but the design is different

@@SirensOfSpartanburg I knew that, I just meant that they're both 9/12 single-rotor with a 3-port undertone and they don't get to full pitch with a sluggish windup. Sure, the screamer is directional, but it doesn't change the sound itself other than the sirens efficiency

caps are bad

Which recording are you taking about?

@@indymetrosirens5643 This one: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vpO3T4I_YfA.htmlsi=r0uvo92Q3mu7SpRo It was a brand new install at the time.

@@PyroTech4051 The pitch in that recording is a bit lower, but still normal for a 2001-DC

💀

where?

@TrainsAndSirens1 What is that white stuff underneath the chopper cap?

@@SirensandThunderbolts1003 Sealant to prevent air leaks and due to chopper cap was damaged.

@@TrainsAndSirens1 ah ok.

This one doesn't for some reason

@@PalmettoStateSirens weird

Thats what i said after listening a few times.

Lol, even the glitching with the solenoids is acting like Harrodsburg!

I fixed it right after. Brush cap fell out this time along with the brush getting worn a bit more.

@@SouthCarolinaSirens i see

It is. It was having a lot of damper issues in the early 2000s, and they ended up disconnecting the solenoids leaving the top one closed during maintenance.

@@SolidSableye The top one works. I flipped the flasher and it was clicking, the spring is broken or stretched. The bottom one is disconnected i think because its contact wasnt sparking.

Cause it’s using the air horn tone
