I'm trying to learn about fire tone outs.
The departments in my county are toned out with a 1 second and 3 second tone. My understanding is that this is Quick Call II.
But some people in the county, like fire coordinators and fire investigators, have their own tones which sound different. Their tones alternate between two frequencies (20 times) for a total of three seconds. Does this pattern have a name? Where can I find more info about it?
Example recording is attached (first 9 seconds)
