I have an idea. (Easier said than done lol) acquire a 4/5 port thunderbolt. Remove the chopper assembly. Buy a 1003 and take out the boring 5/6 chopper... And pop in the 4/5 one... Voila!! A 4/5 Thunderbolt 1003 is born!!
@@Creeperboy099 I'm late, but that is not going to work, you would have to add the whole other set of collector rings and the horn / horn bracket are different on a 1003, the mount is closer to the chopper unlike the 1000T. Unless you wanted to rewire the whole Thunderbolt.
Creeperboy099 I could possibly do this.. considering if I can get my hands on a 1003 And a model 2T or 4/5 port thunderbolt 1000T, witch is actually a possibility, but it’s hard to get a 1003 solenoid assembly even from west shore.. and even if you do you still have to have an rcm3...
no for a short time they did make the 4/5 1003's if im not mistaking there was one in Michigan and it had a beautiful sound. the thunderbolts were made from the 1950's to the 1990's and the early dual tone thunderbolts were 4/5 and when the 1003 was introduced i believe it was still a choice of what combo you wanted. the thunderbolt only had 3 chopper choices 5 port 4/5 port or the common 5/6 port. so yes 4/5 thunderbolts are real...but 5/6 1003's were most common.
Cemoman17 You can also request a synth by commenting and i will do it...right now i am working on a city ambiance of Whelen WPS 2810 in steady and a distant single tone Screamer in wail. creepy.
The siren winds up and when it peaks the electric current going to the field windings reverse causing a the rotor to "choke" with the assistance of a clutch i do believe
+Hero Token Most common use of it I think, this same guy has a Nuclear Meltdown simulation that uses both the pulse and the hi-low, but I think realistically it would be only the pulse, depending on the area
@@SNIXC I think they are the same because undulating hi lo is hi lo hi lo hi lo hi lo hi lo brrrrrrrrrrr hi lo hi lo hi lo hi lo hi lo brrrrrrrrrrr and alternating wail is hi lo hi lo hi lo hi lo hi lo hi lo hi lo hi lo hey loo hey loo hi lo hi lo hi lo hi lo hi lo brrrrrrrrrrr. Is it the same? Yes, same signal but also no because the sound is not the same
How do these sirens change their low pitch sound to that more smooth note like sound? (I'm not talking about the solenoid a, i mean the general sound when they do hi lo)
WELL I guess the best way to explain that is Musical theory, timbre and all that Jazz... but when the thunderbolt does high-low it is switching in between two port combinations 5 port to 6 port alternately. when a thunderbolt does high low it no longer has a overtone. well it does but it is muted significantly causing a cleaner smooth sound.
No, i know how they switch back and forth, but in saying the normal alert is really low and rough, and the hi lo sounds more smooth and note like. For example, take the hi lo tone and take out the high lo part for just a basic thing. It sound much different from when you actually click alert or attack.
+Corey Smith I think the main reason is because on alert or attack the air from the blower is being shared out between the two rotors and for Hi lo all the air is just going through one rotor at a given time
The University Park 1003 is the only known 1003 that came from the factory with a 4/5. There is another 1003 that was swapped with a 4/5 that occasionally runs hi-lo but unfortunately the blower is reverse wired.
@@disconnectatfunniez9189 sorry it took forever to get a reply. I think I have an answer. I do believe the other 4/5 1003 he's talking about is in St Paul, NE. Here it is doing alternate wail and I do not own the video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0bNxJVEk5yU.html
Fnap_ World_7765 the T only belongs to “1000T, 1000BT,1000BTSB, etc.. it means it’s DT, or “Dual Tone”... 1003’s are already dual tone.. 1003A three phase, 1003B single phase.. 1003ASB, Thunderbolt 1003 A series B... go research this.
