AnalogPLUS detector family

The DO1133A point detector cannot be replaced by a multiple protocol detector.
The following applies to connecting external alarm indicators:
If the external alarm indicator is connected to only one individual detector, there
l
are no limitations.
If only original AnalogPLUS detectors and FDOOT241-A3 point detectors are
l
used in combination wit base adapter FDB241, there are no limitations.
If several FDOOT241-A3 point detectors are to be merged on an external
l
alarm indicator, we recommend using the FDB241 base adapter.

SIGMALOOP detector family

The SDF3500 point detector cannot be replaced with a multiple protocol detector.
The following applies to connecting external alarm indicators:
If the external alarm indicator is connected to only one individual detector, there
l
are no limitations.
If only original SIGMALOOP detectors and FDOOT241-A4 point detectors are
l
used in combination with base adapter FDB241, there are no limitations.
If several FDOOT241-A4 point detectors are to be merged on an external
l
alarm indicator, we recommend using the FDB241 base adapter.

Interactive detector family

The DB1151A detector base cannot be replaced with a Sinteso detector base if
l
the detector is operated interactively. An FDB251 base adapter must,
therefore, always be used.
On an interactive detector line, an external alarm indicator may only be
l
operated on an FDOOT241-A5 multiple protocol detector via an FDB251 base
adapter. The external alarm indicator must be connected to the DB1151A
detector base.
The point detectors DOT1151-Ex and DT1151-Ex may not be replaced with
l
multiple protocol detectors.
If an FDOOT241-A5 point detector is mounted in interactive mode (factory
l
setting) on an addressed FDSB291 sounder base of an FDnet system which is
in operation, the sounder base may produce one or two alarm sounds. The
alarm sounds can be prevented as follows:
– Change the FDOOT241-A5 point detector to FDnet mode with the
FDUL221 line tester before mounting in the sounder base.

Detector family with MS8/PMT pulse detection technology

On an MS8 detector line, an external alarm indicator can only be connected to a
multiple protocol detector if using a Sinteso detector base.
