Fire Alarm System

Anyone has a reference standard that explain the types of fire alarm sound has to be?

Some info in: [URL="http://www.cooperfire.com/sites/default/files/docs/CC1608_Fire%20Systems%20Design%20Guide.pdf"]Fire Systems Design Guide[/URL]

Here is about: [URL="https://law.resource.org/pub/in/bis/S03/is.13735.1993.pdf"]AUDIBLE EMERGENCY EVACUATION SIGNAL[/URL]

tks for the reference, but I still can't find what I'm looking for.
I'd like to know how to decide the ring type of an alarm signal, should it be the sirene or bell (ringing) type.

Well, if you know what are you looking for, I'm sure you will find.
Here are some more examples on alarm types: [URL="http://www.marineinsight.com/misc/marine-safety/different-types-of-alarms-on-ship/"]different-types-of-alarms[/URL]

selmagis, thanks for your posts.

Really useful for reference.
In my place, we use the ringing bell for indoor alarm. how about for outdoor, should we should the same type or can we use the siren type?

For consideration, our yard are located next to the sea with size of 5 hectare and a lot of worker doing fabrication in the open yard.
