Changing over from FDnet to collective
When changing from an FDnet detector line with FD20 detectors on a collective
line, or when new detectors are used on a collective detector line for the first time,
collective detector bases are mandatory!
WARNING
Removal of the devices cannot be detected when the wrong detector bases are
used.
Fire may spread unhindered.
Only detector bases FDB201 and FDB201-AA as well as sounder base
FDSB292 may be operated on a collective detector line.
Changeover is normally performed automatically. With some detectors, a
temporary fault or alarm may occur during changeover.
Changing over from AnalogPLUS detector line to FDnet detector line
or from FDnet detector line to AnalogPLUS detector line
The changeover must take place by reading in the line several times. Repeat the
reading-in process until the correct number of installed detectors per line is read in.
The line must be switched off for around 30 s between reading in.
Recommendation: Use the line tester FDUL221 for the changeover.
Changing over from SIGMALOOP detector line to FDnet detector line
or from FDnet detector line to SIGMALOOP detector line
The changeover must take place by reading in the line several times. Repeat the
reading-in process until the correct number of installed detectors per line is read in.
