Switching over the parameter set
In addition to selecting the parameter set, the point detectors with ASAtechnology
enable time- or process-controlled switching over of the parameter sets
(Manned/Unmanned switchover). The time- or process-controlled switching over of
parameter sets allows the detector to be used in places where the situation
changes significantly on a regular basis (e.g. kitchens, production halls).
Parameter sets which can be loaded
The detectors have several permanently programmed parameter sets. For special
applications new, additional parameter sets can be downloaded in the field
(depending on the control panel).
3.1.3 Features of the 'Technical Ambient Supervision 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:
l Threshold value for temperature
l Alarming when the temperature threshold value is exceeded or undershot
l Hysteresis range
Parameter configuration is carried out using the software 'Cerberus-Engineering-
Tool'.
