detector line
w One fire detection installation is installed for collective detector lines.
w Detector bases DB721D are installed on the detector line.
w Point detectors OOH740 are installed in the detector bases DB721D.
1. Install a fire detection installation with one C-NET detector line
2. Remove the point detector from the detector base.
3. Remove the diode unit from the detector base DB721D. See the chapter
'Removing the diode unit [➙ 93]'.
4. If a resistor for selecting a parameter set in collective mode is installed in the
detector base DB721D: Remove the resistor.
Because the resistor is no longer needed, e.g. the connection wires of the resistor
can be cut using a wire cutter or another cutting tool.
5. Install the point detector on the detector base.
6. Repeat steps 1 to 5 for each detector base.
a The fire detection installation detects the point detectors on the addressed
detector line during commissioning.
7. During commissioning, check the set parameter set on each point detector. If
necessary, select another parameter set.
a Migration is complete.
If there are a lot of collective point detectors on one stub, it is often the case that
not all of the detectors are detected when the detector line is first started up. In
this instance, restart the detector line. Repeat this process until all of the
detectors are detected by the control panel.
