"HI-LO AUDIBLE WARNING SOUND (CHP-R-2020-06207)" lists three specific approved Hi-Lo Evacuation tones, but by frequency and California name. Each has a 1 second cycle.
I would have thought that Whelen Carbide programming or the like would have this designated by now, but it doesn't.
The three are:
659-554 European Hi-Lo
932-740 USA Hi-Lo
1244-1046 California Hi-Lo
So, what are the Whelen names, let's say, for these tones? Like "Swiss Tone" or "DIN" ... I saw someone mention German Land tone, but I'm not sure if that is one of the approved ones or not.
Maybe someone can identify which ones are which with a frequency meter or something.
Just curious ... It hasn't rained here for 61 days so I might have to try out something like this soon.
