For a correct operation of the supervision, it is
important that the loudspeaker line has the
characteristics that are listed in section 12.6.5. Also, the
minimum total loudspeaker impedance at 70 kHz is
important. This impedance depends on the quality of
the transformer in the loudspeaker and the number of
loudspeakers in the line. The loudspeakers of Bosch
Security Systems are designed with this impedance
criterion in mind.
The power rating for any loudspeaker that is used with
the loudspeaker supervision must be between 0.75 W
and 60 W.
Proceed as follows to install the loudspeaker supervision
board in a loudspeaker:
1 Set the address of the board with the S700 and S701
address selectors (see section 12.4).
2 Use the corner holes in the board (see figure 12.5) to
install it in a loudspeaker. The coils on the PCB must
be kept at a distance of 30 mm or more from the
loudspeaker magnet and a distance of 50 mm or
more from the loudspeaker transformer, otherwise
the magnetic fields can disturb the correct operation
of the board.

Note
The installer shall only use EN54-24 compliant
loudspeakers for emergency sound systems in
Europe.
Note
See the installation instructions of the
loudspeakers for more information.
Note
To install the board in, for example, a box, use
the universal brackets (LBB4446/00). Connect
the board to a bracket using the middle holes
(see figure 12.5).
