As far as I know, there’s only two videos of it on the entire internets…
Many of the comments say that it’s a Simplex 2001/2120 voice system, while others say it’s Pyrotronics (CPV-90?) or Edwards.
My original hypothesis was that it was the message contained on the old Simplex tape player featured in that recent Techmoan video, but the audio on those tapes was the same message used on its digital counterpart.
Inspired by that video, I did the same tape-respooling thing on the cartrette assembly I bought on eBay a few years ago, and it was the same message again! So now, I don’t really see any evidence that this was a Simplex system at all.
So, any thoughts on what it might be?
I’m also curious about the purpose of the DTMF “111” that’s part of the message. Is it used to verify signal integrity, where failing to detect that after X seconds will trigger a trouble condition? Is it used as a “message start” demarcator? Is it just a generic attention tone?
The script sounds similar to the Edwards message, but the voice sounds like the FCI FireVac III/Honeywell W940 voice used in the Entergy Tower fire alarm video. My theory is that it is not an early Edwards, but, judging by the Techmoan video, it is a Simplex 2001.
NewAgeServerAlarm commented on the first video (the hotel video) and stated that the system was a Simplex 2001 because of the three beeps before the message.
I’m aware of the comments but I’m somewhat skeptical, for reasons described above. A model number or, even better, seeing the actual panel in action would be awesome!
Another clue could be the high-pitched slow whoop in the veterinary video. Anyone recognize it?
I believe the hotel is an FS90 as the voice sounds like the Entergy Tower and Steelcase Pyramid voice (as both have FS90s with the same voice) and the veterinary building has an IRC-3 due to the slow whoop and a different voice.
Edit: after Mimi replied, both may be IRC-3 panels as the slow whoop in the veterinary video is the EST whoop and the script in the hotel video is the EST script.
I know there is a video of the Flamingo in Las Vegas that had an FS90 with the longest slow whoop to date on an FS90 (as long as the Steelcase Pyramid.) The tones also sound different as well.
