4.6.1.1 Temperature monitoring
Temperature monitoring compares the current measured temperature with a preset
threshold value.
You can select the following comparisons:
l
Temperature exceeded: Alarming takes place when the measured temperature
exceeds the set threshold value.
l
Temperature undershot: Alarming takes place when the measured temperature
undershoots the set threshold value.
The threshold value can be selected within the permissible ambient temperature.
You will find specifications for the permissible ambient temperature in chapter
'General (irrespective of the detector line)'.
Hysteresis ranges
You can set two hysteresis ranges:
l
Normal hysteresis range with a range of 1 °C.
l
Large hysteresis range with a range of 5 °C.

4.6.2 Configuration
You can configure the point detector as follows:
Adjustable values
Notes
Normal hysteresis range
Hysteresis range of 1 °C
Large hysteresis range
Hysteresis range of 5 °C
Temperature [°C]
Permissible temperature range: -20…+70 °C
Adjustable increment: 1 °C
Temperature undershot/
temperature exceeded
Selects whether the message should be sent when the set
threshold value is undershot or exceeded.
4.6.3 Default settings for the 'Technical Ambient Supervision
Message'
When the point detector is delivered, the 'Technical Ambient Supervision Message'
mode is switched off.
You can switch on and configure the 'Technical Ambient Supervision Message'
using the 'Cerberus-Engineering-Tool' software.
You will find more detailed information in the fire detection system documentation.
