When planning a modernization, the following limitations must be taken into
account:
The following devices can generally not be replaced with a multiple protocol
device:
– All flame detectors
– All manual call points
Note the information provided in document 001508 relating to installation
(calculation of the capacity layer). See chapter 'Applicable documents'.
All detectors that have not been replaced must be replaced with detectors from
the 'Sinteso' or 'Cerberus PRO' product lines when changing over to
FDnet-Ex/C-NET-Ex.
Limitations exist when connecting external alarm indicators. You will find more
information in chapter 'Limitations on detector families'.
Only the 'stub' topology is permitted in areas at risk of explosion. The following
are not admissible:
– 'Loop'
– 'Sub-stub on loop'
– 'Sub-stub on sub-stub'
– 'Sub-stub on stub'
– Several stub branches from one location.
You will find information about detector compatibility in
documents 008331 (Sinteso) and A6V10229261 (Cerberus PRO).
You will find information about the FDnet/C-NET detector line topology in
documents 008843 (Sinteso) and A6V10210362 (Cerberus PRO).
You will find information about the FDnet-Ex/C-NET-Ex detector line topology in
document A6V10324618.
