4.4.1 Ambient features
In markets where the use of the 'Technical Ambient Supervision Message' is
permitted, the point detector can be positioned above or near objects which require
the operating temperature or CO concentration to be monitored to prevent
damage.
The following ambient conditions are detected in 'Technical Ambient Supervision
Message' mode:
● An increase or decrease in temperature
● An increase in CO concentration
You can set the following parameters using the 'Cerberus-Engineering-Tool'
software on the control panel:
● CO concentration or temperature threshold value
● Alarming when the temperature threshold value is exceeded or undershot
● Alarming when the CO concentration threshold value is exceeded
● Hysteresis range
You will find more detailed information in the fire detection system documentation.
