List of available alarm parameters
Type Uni-sweep
frequency1: pitch at sound-start in Hz (min 40Hz, max 9999Hz) is swept until frequency2 is reached.
frequency2: pitch at sound-stop in Hz (min 40Hz, max 9999Hz).
time: duration of the sweep - Freq1 to Freq2 - in seconds., (min 0.01s, max 99.99s).
ratio: duty-cycle of the square wave in percent, (min 1%, max 50%)
repeat: number of repetitions of the sweep Freq1. > Freq2 (min 1x, max 9999x).
0000 corresponds to infinite repetition.
Type Bi-sweep
frequency1: pitch at sound-start in Hz (min 40Hz, max 9999 Hz) is swept until frequency2 is reached.
frequency2: reverse frequency of the sound in Hz (min 40Hz, max 9999Hz) is swept until frequency1
is reached.
time: sweep duration from freq1 to inversion point in sec., (min 0.01s, max 99.99s).
The duration of the sweep freq1> inversion point > freq1 is symmetrical.
ratio: duty-cycle of the square wave in percent, (min 1%, max 50%)
repeat: number of repetitions of the sweep Freq1.> inversion point (min 1x, max 9999x).
0000 corresponds to infinite repetition.
Type continuous sound
frequency: pitch of the sound in Hz (min 40Hz, max 9999Hz)
ratio: duty-cycle of the square wave in percent, (min 1%, max 50%)
time: duration in sec., (min 0.01s, max 99.99s). 0.00s corresponds to infinite duration.
