Installed point detectors can be replaced e.g. during scheduled maintenance visits by a service technician. 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. -
Page 11: Step-By-Step Modernization
Principles and conditions of modernization Step-by-step modernization 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. -

Page 16: Base Replacement
Risk of explosion ● When modernizing the collective Ex detector line, point detectors FDOOT241-A9-Ex and OOH740-A9-Ex may only be used with detector bases FDB20x or FDB22x. Do not use detector bases from the AlgoRex product range or base adapters. You will find information about installing the detector bases FDB20x and FDB22x in document A6V10208546. -
Page 17: Configuration Of Detector Type
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. If the point detector FDOOT241-A9-Ex or OOH740-A9-Ex is intended to replace a heat detector: Also install a standard resistor to set another parameter set. -

Undertaking modernization 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. -
