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
