    'Suppression (5)' parameter set. Default (0): If no parameter set is selected, the point detector automatically uses a preset parameter set. In the case of the point detector OOH740-A9-Ex, this is the parameter set 'High Compensation (7)'. Balanced (4): The 'Balanced' parameter set reveals a balanced response behavior regarding reaction to fires and robustness to deceptive phenomena.
