Grand Daddy of signaling devices!

Good day all.
I have to ask about signaling devices.
In this new plant we have MANY horns, buzzers, strobes and stack lights. The signal for all kinds of things as you can imagine. But now I have a need for the grand daddy of attention getters. I need to signal to an entire production area that an event is happening and we need all available hands at a specific area. This area is a massive room with many running machines, conveyors ect. So I really need to find something unmistakable and unavoidable to tell people what is happening.
I am wondering what you guys / gals may use for similar signaling in your plants. The common AB stack signal just will not suffice.
I am imagining a train horn or something I can give a few quick blasts on.

Thanks
 
I would put a few loud buzzers with strobe lights, similar to a fire alarm annunciator, but louder & NOT RED!

Standard 120VAC buzzers with strobe lights on the junction box would work, 1 every 30 linear feet with loud machinery, every 50 -75 feet if not a loud shop.
 
Oh, one thing.
If you place one op these things inside a building, you may have to consider noise restrictions in the work place. You dont want to get sued for causing someone hearing damage.
Maybe consider a really powerful flash rather than an audible device.
 
What about giving everybody a vibrating pager which displays a message designating where to report?

I love the Hemi siren. That is the one I must have. Just have to get QA to allow it on the plant floor.

Thanks guys!
I have a few ideas now.

Brings to mind the idea I posted in another thread - electronic dog training collars with the remotes wired to the control panel. Fast response by all involved!
 
I'm sure there's been plenty of research on this, but in my opinion a siren means "all hands respond", while a repeating horn is just a warning that can be ignored.

I would recommend one that sounds like a civil defense siren rather than like a fire-truck or police-car siren. Anyone who has lived in a tornado-prone area will know the sound by instinct.

One of my colleagues has a phone ringer sound that never fails to pull my attention and quicken my heart rate: it's the Boeing ****pit warning for excessive rate of descent: "[whoop] [whoop] Pull up!"

I do not recommend that as your general assembly siren. And if you make it your phone ringer, don't be surprised when you come back from lunch to find your phone has mysteriously turned off.
