Current job: Mircom horn-only devices (the whole building has a few different horn devices).
My school has an EST3 system with a large variety of alarms. The older main building has 2 floors with 2 different kinds of alarms. The alarms in the basement section are Simplex 4903’s in the hallway and 4906 strobes in the classrooms. The upstairs section has Wheelock MT’s in the hallway and 4906 strobes in the classrooms. The older gym and the theater have Gentex speaker strobes and the theater has 1 of the 3 annunciators in the system. The newer part of the school has EST Genesis horn strobes and speaker strobes. The smaller art building has System Sensor Spectralert classic horn strobes. And the Newer gym/Arena has EST Integrity Speaker strobes. The smokes and pulls are all EST SIGA series devices. I don’t know when it was installed, but that’s the system.

Welcome to The Forums!
Wow, that’s definitely a huge mix of devices. Do the speaker/strobes all play a typical EST message? I’m guessing they will probably replace or upgrade the EST3 system in the (hopefully near) future. I wonder if they will replace some of the devices and change to all speaker/strobes to comply with modern code, or if they will just replace the panel. They will probably just upgrade to EST4, but almost anything (except probably Silent Knight) would be an upgrade.
I don’t think the current system is getting replaced anytime soon. Being such a large complex, it would cost way too much to replace. It may not sound like it but our school system is pretty small.
One of the theater speaker strobes
If im not mistaken, the voice evac is a Potter EVAX panel and it plays the code 3 whoop.
this is a picture of the theater Annunciator

My middle school also had an EST system with an EVAX panel (The system had mainly horn strobes though.)
My schools mostly horn strobes too
Not sure why that would be the case if the main panel is an EST3 (which I’m pretty sure can have integrated voice & thus doesn’t need a separate voice panel, unless maybe that EST3 is replacing a previous FACP, which would explain the Gentex speaker/strobes (since of course it’d be much more likely to see Edwards speaker/strobes on an Edwards system).
the main panel is the smaller square est 3 with external voice evac
“smaller square est 3 with external voice evac”? What? Your explanation seems to make absolutely no sense to me.
Oh, that, okay. That EST3 has an external voice panel despite being voice-capable itself?
For some reason yes. Maybe they didn’t option it in?
Maybe. Seems like a dumb thing to do though when they could have just had the EST3 itself handle the voice portion (though like I said that may be because the separate voice panel was there already from a previous panel, & thus they just kept it there & tied the EST3 into it when the latter was installed).
That, or the EST3 was there before the voice panel.
that doesn’t make much sense to me.
Well, that school might have had a horn/strobe system previously, & then when it was upgraded to be voice-capable they put in a separate voice panel to accomodate for the fact that that particular EST3 wasn’t made with voice in mind (though why they didn’t go with an Edwards voice panel to match the EST3 I have no idea).

Edwards did rebrand EVAX panels at one point.

Yk what. It is probably the Edwards rebranded one
Do you know what the voice message says? EST did rebrand EVAX panels with more tones (including the unique code 3 whoop) but with a different voice message.
