This is where the 4003 and 4100 tones come from. nickpiegari.com... Thanks wileyk209zback and Alex H. for letting me use the excerpt from your video!

WOW. This is awesome. This is like the Moog of fire alarm voice evacuation systems.

I heard Honeywell had a SIMILAR one, but it also included a voice generator as well. It was the SAME weird whoop sound (like a person tuning a violin incorrectly).

ooh, very interesting! I wonder if it was a circuit that everyone lifted from some electrical engineering textbook or something

So tell me since when did this 2001 generator used these cassette tape for voice evac back then before it was replaced with 4100 voice evac in 1988?

That chiming sound; I recognize it! The hospital I used to work at made a similar chiming sound in areas that had Simplex LifeAlarm speakers on 2903 light plates, along with over the intercom speakers (the intercom was tied into the fire alarm system.) They still have a few 2001 panels controlling the system, along with some 4100-series panels as well (I remember the emergency wing making a temporal version of the older Simplex chime tone; they have a 4100 system in that wing with 4903 speaker/strobes.) A VERY interesting Simplex setup, with a huge mix of stuff from the '80s to today (the Simplex system was first installed when the hospital was expanded in 1982.) There are even a few areas with horns: the radiation therapy wing has Space Age 2DCD+AV32 horn/lights, and a couple other wings have TrueAlert horn/strobes.

+wileyk209zback, is there a pitch wheel on that tone generator?
@ZakWolf9 жыл бұрын
I wouldn't be surprised if there were.
@OrthodoxChristianBeliever9 жыл бұрын
cause there's a similar chime tone to that chime tone for the simplex 4100 when the technitian utilizes the supervised microphone, but it's just a bit higher pitched
@CODMarioWarfare6 жыл бұрын
Yeah, a pitched variant on those tones is still used today. Off the top of my head, I remember a common clip used for speaker tests, supposedly from the 4003 and related, that started with 2 of those chimes followed by the slow whoop. I remember a multi-part high rise video in which zones that were not activated had that chime running every couple seconds as a standby tone.

Sadly, the hospital had an electrical room fire a couple months ago, so as part of the repairs and renovations, they are now upgrading to a fully-addressable Simplex 4100ES voice-evac system. The 2001 panels are now likely gone, along with the 4100 tied into them, as they already have the 4100ES panels in place, and they will soon be replacing all the conventional devices and the older LifeAlarm speaker/lights with the modern addressable Simplex equivalents (though they will probably use conventional TrueAlert speaker/strobes).

oh i love the classic original 2001 / 2120 with a hint of 4100 series since 1988 too it's better it's so nostalgic. It’s 4100’s 36th since it was made in 1988

Have you ever traced the tone generator cards? I'm assuming they're all 555 timers or op amps.
@NicksMadScience4 жыл бұрын
I must've at some point; the whoop card has some homemade modifications to it, apparently :D The chime is 555-based, the whoop circuit is based on, uh... some sort of voltage ramping thing? Not sure, it's been a while. I love that whoop tone so much; it's just so WEIRD and I'd love to learn more about how it works. I snapped some photos if you're curious: nickpiegari.com/misc/nicksmadscience/simplexcards/

my grandmother, when she was alive, lived in an old folks building, and the system at the time, it was twenty to thirty years ago, it was a simplex 2001 fire alarm control panel w a voice evacuation system, and it made that same exact slow whoop tone. No pre-recorded voice though. The last time I saw photographs of the lobby where the 2001 fire alarm control panel was, they replaced it w a mircom system.

The buttons and knobs to the left of the tone generator cards, what r those?
@nickpiegari17889 жыл бұрын
That's the "mixer" part of the board. I believe those are the trim controls for the tone generators, mic input, and tape / message player input. WAY fancier than any modern system, as far as I know.

did they ever use a recording of the straight, tone generator? Cause it seems like they did, and they use that for the code three tone
