Ah the ol UMMT-S17s, my school had these all over the elementary end of my elementary/high school building, and they used to scare the living day lights out of me, but then I started to like them. They were all in continuous.

@@electromaniac5573 I looked up "oscillating relays", and all the examples I could find have them oscillating at many times per second. What I think you want is a timer circuit.

The U-S17 was one reason why Wheelock sued Siemens
Their speaker strobe series right before the lawsuit was called the clear speak series and included both wall amd celling models
For these Siemens rebranded wheelock devices, they take Faraday sync as I found out, and was able to get them to sync with my U-MCS
Nice
Siemens is truly amazing
this reminds me of a crazy system i saw in a building once
Do you know what kind of panel it was? What was the setup like?

What was so similar before?
Cool but next can you do a video of your whole fire alarm collection
We had these when I was in high school
4:00 My school has these, they're Siemens versions too
Will there be a video on the Adam's elevator bell.
Now that you mention it...
I belive the s-17 has other tones on it too
And of course we have the s-17's on synced temp 3 at my high school, set to MAX VOLUME Scaring the f*** out of me every time.
And surprisingly they have audible silence too
Look up fire alarm at Panera bread
AKA a place I used to eat at
4:03 i have that alarm
My school 3:21
i must admit, i absolutely hate siemens.
Yeah, the panels aren't the easiest to work on. I like Simplex and Fire-Lite.

@@electromaniac5573 Why an oscillating relay?
