Message'
The 'Technical Ambient Supervision Message' cannot be configured on all fire
control panels. Observe the information in the 'List of compatibility'.
'Technical Ambient Supervision Message' mode detects an increase in
temperature caused by hysteresis above a specified threshold.
Temperature monitoring compares the current measured temperature with a preset
threshold value.
You can configure the following parameters for the point detector:
● Threshold value for temperature
● Alarming when the temperature threshold value is exceeded or undershot
● Hysteresis range
Parameter configuration is carried out using the 'SintesoWorks' software.
