Alarm Volume parameter
The alarm volume parameter sets the duty cycle of the pulsed alarm signal. At 0%
it's off, at 100% it is continuously on (no pulsing). The setting is used the moment the
alarm is switched on. Changes during a running alarm will not be used until the next
following alarm activation.
The setting can be changed in the Web client using the PPO to container write mac-
ros, in the Web client over painter / teq refresh triggered painter properties including
button use, or it can be changed over a FTP rewrite in the configuration file.
Alarm Frequency parameter
The alarm frequency parameter sets the frequency of the 'beeper' during the active
pulse periods of the pulsed alarm signal. If set to low in respect to the pulse-width
nothing will be heard. The setting is used only at the moment the alarm is switched
on. Changes during a running alarm will not be used until the next following alarm
activation.
The setting can be changed in the Web client using the PPO to container write mac-
ros, in the Web client over painter / teq refresh triggered painter properties including
button use, or it can be changed over a FTP rewrite in the configuration file.
Interval time parameter
The interval time is the pulse repetition time period. At for example 50% duty cycle
interval time setting to 200 leads to 100 mSec off, 100 mSec on pulsing.
During the 'pulse on' period the frequency should be set sufficiently high to hear
something. Setting the interval time to 0 switches the acoustic alarm off.
The setting can be changed using in the Web client the PPO to container write mac-
ros. If used on a button it can be set on the button down or button up event.
If the Container write is set on the button down event, at a button touch the acoustic
alarm first will switch off the current buzzer / beep action and restart the next one
with the actual volume and frequency setting as has been set at this moment.
