8 Adjustment of detection settings
The standard settings of the video-based fire detection will be sufficient for the most
customer environments. Nevertheless, there are many ways to adapt the flame and smoke
detection to the requirements of the customer. The detection settings of the fire detection
can be changed in the configuration menu:
1. Go to Configuration and navigate to Alarm.
2. Select Fire detection.
General and special settings for Fire detection are selectable. Anytime you change the
settings, confirm with Set to apply these changes.
If you want to abort, just click on another menu option, for example Audio Alarm.
The Intelligent Video Analytics functions and the video-based fire detection settings can be
changed during operation and will immediately become effective.
8.1 General settings
Following settings change the detection algorithm generally.
Flames
The default setting of the flame size is 1.6% of the picture width. The Min. size can be set with
a software slider. Possible settings are 1.1% to 2.0% of picture width. A red square at the
bottom of the picture visualizes the actual setting in the original size. Small values for Min.
size increase the distance to detectable flames, larger values decrease false alarms.
Verification time [s] of the flame detection can be set to 4, 8, 12 or 16 seconds. The default
value is 8 seconds. Small values cause faster detection (higher risk of false alarms), larger
values decrease false alarms.
Smoke
The default setting of the smoke size is 2.3% of the picture width. The Min. size can be set
with a software slider. Possible settings are 1.6% to 3.1% of picture width. A yellow square at
the bottom of the picture visualizes the actual setting in the original size. Small values for Min.
size increase the distance to detectable smoke, larger values decrease false alarms.
Verification time [s] of the smoke detection can be set from 10 to 30 seconds. The default
value is 15 seconds. Small values cause faster detection (higher risk of false alarms), larger
values decrease false alarms.
Sensitivity
In case of false alarms, you can use a software slider to adapt the value Sensitivity for flame
and smoke to your specific needs. The following table shows the different settings:
