Hallo,
as I used this alarm function in practice couple of times 
I would like to enhance this sound pattern Beep-Beep- 3s pause -Beep-Beep. I can tell for me it is not very helpful to listen for these two short Beeps and the wait next 3 seconds from where the sound goes.
When I hangs around through high forest with wind in my ears and birds chirps it is hard to recognize the direction of the alarm when it comes so sparsely.
First of all Beep is too short (didn’t look into source code but guess it is 100ms) and then 3 second is too long to wait for next Beep-Beep.
It would be perfect to have an option to edit this pattern somehow what do you think guys?
