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
