Re: What tones would you prefer for voice evac?

As far as slow whoops go, I like the classic 4100 whoop tone best. Sounds realistic and attention-grabbing, but not as startling as I think the U/ES one is.

That said, at the risk of being boring, I think 520Hz code 3 should be the standard.

Re: Alternatives to System Sensor for Notifier notification

The initial question has pretty much been answered (seems Wheelock and Gentex would be the best bets). But just out of curiosity, what types of NA's are you planning to install? Horns, speakers, or chimes? Wall or ceiling mount?

Re: Strange fire alarm upgrade at the local Aldi storr

I know it took me a while to figure out what the signals were in the main part of my local Wegmans supermaket. I had seen a Wheelock AS outside, and wall-mounted NS's in the dining area, but I didn't notice until later that there were also AS's high up on the ceiling in the main part. So I wouldn't ...

Re: History of fire alarms, by generation

I feel like the second generation is more mid-50s to mid-60s, and the third is more late '60s to very early '80s. I think the Federal 30A also deserves a mention for the second generation, and the Faraday and Federal horns (Simplex 404x and 405x respectively) for the third. But otherwise, it's prett...

Re: Siemens rebranding EST equipment

An eBay search does show some Siemens-branded EST equipment. How long ago was this? Does it predate Siemens buying Cerberus Pyrotronics/Faraday? I know Honeywell used to rebrand EST equipment before they bought Pittway.

Re: Simplex 4048 manufacturer found

From what I'm seeing online, Thomas was a division of Benjamin who made the 4030. I guess this was the successor to that horn.

Re: Target remodel and fire alarms

I guess bells are still the preferred signal there? It's certainly a universally recognizable sound. One of my nearby Target locations was recently remodeled, and got white ceiling-mounted System Sensor L-series horn/strobes and remote strobes. (First time I've seen those in person.) The old red wal...

Re: Most Absurd Description of a Fire Alarm Sound

The generic description in the school district I grew up on seems to be either "a series of blasts" or "a long blast" of "the bell or horn". My elementary school had the "series of blasts" description throughout my time there, which definitely fit the pulse of the original Standard 30A's, and I supp...

Re: Early Wheelock Mini Horn?

I heard these signals online when the video was up. It might not have been a mechanical tone. The two notes were about an octave below the ones on the Wheelock MT hi/lo, and had more of a screechy/raspy sound to them. It was making some type of coded pattern similar to the military chant "Left, left...

Re: Early Wheelock Mini Horn?

I'm guessing they'd still sound like a GX-90/typical smoke detector sounder. I'm still curious about the "slow whoops". And those weird-sounding signals in a UAlbany dorm that had the octogonal grilles and 7002T-type strobe, but made a weird sort of tone that sounded like a mechanically-generated Hi...

Re: Wheelock 7002T coming back!

TBH, if they decided to redo the 7002T, it would probably look like a 34T with a ZNS strobe put through the middle with rounding done to "modernize" the body of the horn. If I had to guess, the model number would probably be Wheelock MHS (mechanical horn/strobe) or MH (mechanical horn). Sadly, skip...

Re: Wheelock 7002T coming back!

If only this were real! I wonder why they didn't make one back in the mid-90s, as other companies were still using mechanical horns at that time. That actually makes me wonder - was the 34T still in production for a while after the 7002T was discontinued? Would have been interesting to see those ins...

Re: New UL listed products from Chinese manufacturers

Interesting to see these. They look a little odd but I welcome more variety in the market. I wonder how they sound.
