2 Principles and conditions of modernization Using multiple protocol detectors 2 Principles and conditions of modernization 2.1 Using multiple protocol detectors 2.2 Characteristics of 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.
Principles and conditions of modernization Step-by-step modernization 2.3 2 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.
2 Principles and conditions of modernization General limitations on modernization 2.4 General limitations on modernization 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'.
Principles and conditions of modernization Limitations on the collective Ex detector family 2.5 2 Limitations on the collective Ex detector family WARNING Replacing an intrinsically safe point detector in an area at risk of explosion Risk of explosion ● ● ● Before replacing the point detector, carry out all necessary safety calculations and safety assessments. Document evidence of explosion protection.
3 Point detectors and base adapters 3 Point detectors and base adapters The table below shows which point detectors can be replaced with multiple protocol detectors: Detector family Collective Ex: Siemens/Cerberus Point detectors which can be replaced DO1101A-Ex DT1101A-Ex DT1102A-Ex Replaced with Multiple protocol detectors Base adapter FDOOT241-A9-Ex --- OOH740-A9-Ex --- The point detectors FDOOT241-A9-Ex and OOH740-A9-Ex may not be installed using base adapters.
Undertaking modernization Step 1: Detector modernization 4 4 Undertaking modernization 4.1 Step 1: Detector modernization The following steps must be taken during each modernization: 1. For information about installing new detector bases FDB20x or FDB22x, see chapter 'Base replacement [➙ 16]' 2. For information about configuring the detectors, see chapter 'Configuration of detector type [➙ 17]' 3.
4 Undertaking modernization Step 1: Detector modernization 4.1.1 Base replacement On collective Ex detector lines, when replacing the point detector with a multiple protocol detector, the switch can be made to a Sinteso detector base.
Undertaking modernization Step 1: Detector modernization 4.1.2 4 Configuration of detector type The point detectors FDOOT241-A9-Ex and OOH740-A9-Ex can be set to the existing detector type using parameter set resistors. Procedure: Detector bases FDB20x or FDB22x are installed. 1. Install a point detector FDOOT241-A9-Ex or OOH740-A9-Ex directly in the new detector base as a replacement for a point detector DO1101A-Ex. 2.

Undertaking modernization Step 1: Detector modernization 4.1.3.2 4 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.
4 Undertaking modernization Step 2: Replacing the control panel and changing over to FDnet-Ex/C-NET-Ex protocol 4.2 4.2.1 4.2.2 Step 2: Replacing the control panel and changing over to FDnet-Ex/C-NET-Ex protocol 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.
Undertaking modernization Step 2: Replacing the control panel and changing over to FDnet-Ex/C-NET-Ex protocol 4 Migration to the following protocols can take place, depending on the control panel being used: FDnet-Ex: Use the multiple protocol detector FDOOT241-A9-Ex Non-Ex Area FDnet Ex Area FDnet-Ex FDOOT241 -A9-Ex FDCL221Ex FDnet FDOOT241 -A9-Ex FDOOT241 -A9-Ex FDOOT241 -A9-Ex FDnet-Ex FDCL221Ex FDM223Ex C-NET-Ex: Use the multiple protocol detector OOH740-A9-Ex Non-Ex Area C-NET Ex Area C-NET
4 Undertaking modernization Step 2: Replacing the control panel and changing over to FDnet-Ex/C-NET-Ex protocol 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.
Undertaking modernization Step 2: Replacing the control panel and changing over to FDnet-Ex/C-NET-Ex protocol 4.2.5 4 Configuration The multiple protocol detectors are configured directly on the control panel or using the relevant configuration software for the fire control panel.
