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.

Values in parenthesis ( ), example DIN alarm, A20

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.

Values in parenthesis ( ), example siren, A22

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.

Values in parenthesis ( ), example BZB all clear signal, A25
