Hello again. I’m posting this thread as I’m wondering about Unitrol sirens and their history.
Starting off, the Touchmaster.
If anyone noticed the Touchmaster before FS took over had a different sound to it. It had a lower pitched 80K wail and the Yelp had a “bow” sound it, the wail on sweep switches after it peaks. The newer ones don’t have these features. I also noticed some FS Touchmasters still kept these features. Does anyone know when FS phased out the old DN tones from their Touchmaster?
Did any major departments use Touchmaster in bulk?
Alright into the 2nd Unitrol. The 80K
I currently own two 80K amplifiers. One FS and the other Unitrol. I noticed they sound different pitch wise. What was the reason for this change? Also I noticed on a video of the San Francisco Police Department responding, that one of the 80Ks had a fast Yelp compared to the other 80Ks I heard. If possible, can you change the Yelp of the 80K to sound faster?
Third question for this siren. The controllers. Which departments use the 480K, 280K, or FP-183k more often? Also what does the “LV” stand for on the 183k? I noticed on the manual on the 80K the 183k has “off” “man” and “auto” whilst on the LV is has “wail” “yelp” and “Hilo”. Was this specifically changed for departments?
Alright, last siren. The Omega.
When I saw LAPD responding with it, I noticed they used the priority tone. Did they intentionally set it up like that or was it just the officer making his own modifications?
As you also may know, the Omega has a sweep mode which sounds like an electronic game. Has anyone heard an actual police car use this feature? Also does the FS and DN Omegas have any differences like the other 2 Unitrols?
I apologize if I wrote too much as these questions have been bugging me. I also apologize for the repetitive use of some words. Thank you for taking the time to answer these questions and reading through this post.
