4.3.1.4 Default settings
When the point detector is supplied, the default device parameter set for CO
(parameter set 0, 'Robust EU1') is set.
The optimum parameter set for CO must be selected when commissioning the fire
detection system. The selection criteria are the existing risk and ambient
conditions.
After the commissioning of the control panel, the fire detector is automatically set to
its country-specific basic setting.
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'.

4.3.1.5 Application examples
The table below includes examples regarding the selection of the parameter set for
CO for the point detector. The examples cannot be used universally, but illustrate
typical applications.
Environment Detection behavior wanted Parameter set for CO
Rooms with open fire Very fast response needed 'Static 40 (4)'
Heating rooms
Evaluation of time dependency of
CO concentration
'Balanced EU2 (1)' or
'Balanced US1 (7)'
Combustion or fermentation plants
Very robust behavior towards
deceptive phenomena
'Robust EU1 (0)'
Car parks, automotive workshops
Robust behavior towards deceptive
phenomena
'Balanced EU2 (1)' or
'Balanced US1 (7)'
Underpasses and escape
compartments
Evaluation of time dependency of
CO concentration
'Balanced EU2 (1)' or
'Balanced US1 (7)'
Animal stalls Fast reaction required 'Static 50 (5)'
Chemical labs or production sites
Fast and very sensitive reaction
required
