EST Pre-Integrity speaker strobe?

I found this video of what looks to be EST Pre Integrity/792 speaker strobes going off, does anyone know the model number, and does anyone know the panel?

The speaker/strobe is a 765-7A-006.

I’m not sure about either of your questions, but the whoop tone reminds me of the one in this video (mainly the way the pitch briefly “hangs” at the start before increasing):
Fire Alarm at the Entergy Tower in New Orleans. Floor 21 (youtube.com)

It’s most likely an IRC-3. The whoop sounds different than a Honeywell one.

iirc, the IRC-3 used System Sensor smokes due to the panel using the CLIP protocol. The church in the video has system sensor smokes in this small room when I visited it the other day.

Well the Edwards-EST pre-Integrity speaker/strobe supports it being an Edwards system, but I’ve never heard any Edwards voice system play a whoop tone like that (heck I’m pretty sure the only system I have heard play such a whoop tone is Honeywell’s FS90).

Somewhat related, but these pre-integrity and even some early generation integrity strobes couldn’t sync, even with an Edwards panel. It could be literally any panel with these speaker strobes. An example of this is there is a Siemens system inside grand central station, however they use integrity speaker strobes.

Just because they can’t sync strobe-wise doesn’t mean they can’t operate at all with Edwards panels (especially since unlike Simplex Edwards even today has yet to come out with a line of addressable signals, thus meaning that just about any signal Edwards has ever made should work with just about any of their panels). The whoop tone does support it not being an Edwards system however (or at least fully Edwards given the presence of that pre-Integrity speaker/strobe).

The church does have 270-SPOs by the doors, which support the idea of the church having an Edwards system.

I meant the fact that those speaker strobes could technically be installed on any panel at the time.

270s are installed everywhere, not just on Edwards systems
