Principles and conditions of modernization
Using multiple protocol detectors
2 Principles and conditions of modernization
2.1 Using multiple protocol detectors
Multiple protocol detectors for areas at risk of explosion can quickly and efficiently
replace point detectors that are already fitted on collective Ex detector lines.
The point detectors can either be replaced individually or as a complete detector
line.
Installed point detectors can be replaced e.g. during scheduled maintenance visits
by a service technician.
2.2 Characteristics of multiple protocol detectors
The multiple protocol detectors FDOOT241-A9-Ex and OOH740-A9-Ex may
communicate via different detector line protocols.
These detectors automatically recognize the protocol on the detector line
(e.g., FDnet-Ex/C-NET-Ex or collective Ex) and switch to this protocol.
This functionality simplifies detector line commissioning during modernization
because additional measures are not normally needed on the point detector.

Step-by-step modernization
2.3 Step-by-step modernization
Step-by-step modernization involves firstly replacing the existing detectors with
ones which support both the current detector protocol – hereinafter referred to as
the alternative protocol – and the FDnet-Ex/C-NET-Ex.
The replaced detectors initially continue to be operated with the alternative
protocol.
If the fire control panel is replaced at the end of the modernization project, the point
detectors automatically change over to the new protocol (FDnet-Ex/C-NET-Ex).
The existing cabling can usually be transferred with ease.
These measures enable out-of-date fire detection installations to be gradually
replaced with modern, sensitive fire detection installations with false alarm
immunity.
This document does not cover modernization via the control panel with a line card
of an alternative protocol, e.g. collective.
Step 1: Replacing the existing point detectors with
multiple protocol detectors
The detectors communicate with the protocol of the installed system
(collective Ex).
No changes are required on the fire control panel.
Step 2: Replacing the existing fire control panel with a control panel
Sinteso FC20xx or Cerberus PRO FC72x
At the same time, all peripheral devices that have not been modernized, such
as manual call points and input/output modules, must be replaced with devices
which can be used on the FDnet-Ex/C-NET-Ex.
As an alternative to replacing the control panel, the existing line card in the fire
control panel can be replaced with a line card (FDnet/C-NET).

Step 1: Detector modernization
4.1.3.2 Testing detectors without detector exchanger and
tester/detector tester
The point detectors are highly resistant to deceptive phenomena. This means that
optical fire detectors, for example, will recognize the immediate occurrence of
smoke (such as that which occurs during testing with test gas) as a deceptive
phenomenon and will not trigger an alarm. This is desirable in normal operation;
however, it does make testing with test gas problematical.
To enable detector testing with test gas or hot air, the detector must be switched to
test mode. Testing with test gas or hot air is performed differently on addressed
detector lines and collective detector lines.
Collective Ex detector lines
On a collective Ex detector line, the detector is not set to test mode if the detector
group is switched to 'Test' on the control panel.
Detectors on a collective Ex detector line are switched to test mode for 3 minutes in
the following cases:
Starting up and resetting the detector line
Inserting the detector
Removing the detector from the detector line and re-inserting it
To trigger a detector using test gas, normally 2…4 gas discharges at intervals of
approx. 2 seconds are required. When the detector is in test mode, activation
takes place after approximately 10 seconds.
4.1.3.3 Setting the detector zones to 'Test'
Collective Ex detector lines
Setting the respective detector zones to 'Test' on the control panel does not result
in a situation where the detectors can be activated at speed.
4.1.4 Starting up from collective mode
When starting up for the first time, you must perform the following:
1. Switch the detector line on.
2. Wait at least 30 s.
3. Read in the detector line until all the detectors installed have been recognized.

4.2 Step 2: Replacing the control panel and changing
over to FDnet-Ex/C-NET-Ex protocol
4.2.1 Replacing the control panel or installing a line card
During modernization, we would recommend replacing the existing fire control
panel with a control panel Sinteso FC20xx or Cerberus PRO FC72x.
In the case of the 'AlgoRex' and 'SIGMASYS' product lines,
a line card (FDnet/C-NET) can be fitted in the existing fire control panel (E3M141,
FDC).

Line card
Order number
AlgoRex E3M141 S54405-A9-A1
SIGMASYS FDC S54230-B150-A2
4.2.2 Replacing the remaining peripheral devices
When changing over to the FDnet-Ex/C-NET-Ex, all peripheral devices on a
detector line which have not been modernized must be replaced. This applies to
the following device groups in particular:
All manual call points
– Replace the manual call points with manual call points FDM233-Ex
The alarm indicators must be replaced with alarm indicators FDAI9x-Ex.
Migrating the detector line from 'Collective' to 'Addressed'
The starting point is a collective detector line in which no multiple protocol
detectors are installed yet (bottom detector line in the diagram) or a detector line
which already has all of or some of the multiple protocol detectors installed (top
detector line in the diagram).

4.2.3 Converting collective Ex detector lines
When switching a collective Ex detector line with point detectors FDOOT241-A9-Ex
or OOH740-A9-Ex, the following points must be observed in particular:
Remove the EOL resistors on the collective Ex detector lines.
The safety barriers SB2 or SB3 and DC1192 must be removed and a line
adapter (Ex) FDCL221-Ex must be installed instead. The line adapter (Ex)
FDCL221-Ex provides safe isolation between the non-intrinsically safe and the
intrinsically safe circuit.
There is no need to replace the detector base FDB20x with a detector base
FDB22x.
There is no need to remove parameter set resistors on the terminals for the
external alarm indicator. This does not restrict the function of the detectors on
the FDnet-Ex/C-NET-Ex.
If, on an FDnet-Ex/C-NET-Ex detector line, a point detector is removed from a
collective detector base (such as a detector base FDB201), communication
between the control panel and all subsequent detectors is interrupted. A fault is
indicated on the control panel.
Remove the diodes in the detector bases in the case of mixed collective Ex
detector lines to which manual call points and point detectors are connected.
Check whether only permitted topologies are being used. Only the 'stub'
topology is permitted.
The maximum possible number of peripheral devices per stub must be
checked.
Check whether the max. lengths of line and capacities are within the
permissible data.
You will find more information on safely installing an FDnet-Ex/C-NET-Ex detector
line in document A6V10324618.
4.2.4 Starting up for the first time under FDnet-Ex/C-NET-Ex
When starting up for the first time, you must perform the following:
1. Switch the detector line on.
2. Wait at least 30 s.
3. Read in the detector line until all the detectors installed have been recognized.
The peripheral devices must change to FDnet-Ex/C-NET-Ex mode. We would
recommend using the FDUL221 line tester for the changeover.
You will find more information on the line tester FDUL221 in document 008250.
