The detector operates in the default parameter set as long as the control panel has
not assigned a valid parameter set to the detector.
The following table shows the default parameter set for the point detector
OOH740-A9-Ex in the various sensor modes:
Fire detector Default parameter set
OOH740-A9-Ex in C-NET-Ex operation mode High Compensation
OOH740-A9-Ex in collective operation (no
resistor installed in detector base)
Sensitive, DOO emulation
Upon commissioning of the fire detection system, the optimum parameter set must
be selected based on the existing risk and the ambient conditions. See chapters
'Parameter sets for addressed operation [➙ 35]' and 'Parameter sets for collective
operation [➙ 41]'.
If the point detector is operated on the C-NET-Ex (addressed), it is automatically
set to the basic setting for the country in question when the control panel is started
up for the first time. Individual adaptation takes place using the commissioning
software on the corresponding control panel.
If the point detector is operated in collective operation, it operates with the default
setting when it is first commissioned. In this operating mode, the detector behavior
is adapted on an individual basis by installing configuration resistors in the detector
base.
In collective operation, the selected parameter set is displayed for 3 minutes when
the detector line is started up and when it is reset, by means of the LED for the
internal alarm indicator flashing.
You will find information on the default settings in 'Technical Ambient Supervision
Alarm' mode in chapter 'Default settings for the 'Technical Ambient Supervision
Message''.
