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.
