3.3.1 Parameter sets
The detection behavior of the point detectors is influenced by the parameter sets
so that it can be specifically adjusted to the fire phenomena and environmental
conditions to be expected in the environment to be monitored.
All parameter sets are programmed in the point detectors. During commissioning,
the optimum parameter set must be selected for the conditions at the place of
installation.
On a

detector line, the parameter set must always be set explicitly.
You can select and set the parameter sets as follows:
● Using the 'Cerberus-Engineering-Tool' software
● Directly on your fire detection system (only within the same sensor mode)
You will find a description of the exact procedure for selecting and setting the
parameters in the relevant documentation.
Please note the chapter 'Applicable documents'.
Parameter sets for fire detection in collective mode
The point detector OOH740 can also be operated in collective mode.
There are several parameter sets for fire detection available in collective mode.
The parameter sets are selected in collective mode using resistors installed in the
detector base.
