Warning level 3 is not output in the default device parameter set.
Example for parameter set 1 'Balanced EU2' @ 55 ±5 ppm CO:
At 50 ppm CO, alarming must take place after between 60 and 90 minutes.
At an operating temperature of 80 °C, the CO sensor may not function reliably.
Irreversible signaling of a critical fault therefore follows after four hours.
The point detector may only be used in continuous operation within the specified
temperatures!

4.3.3 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 with the 'SintesoWorks' software.
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'.
