* By default, a spring for mounting the detector in concrete and wooden
ceilings is preinstalled (identifiable by the red marking.) For mounting a
detector in a false ceiling panel you can use the additional, softer spring in
the package. In this use case, the detector must not be subjected to
strong vibrations (> 350 m/s). The shock resistance according to EN 54-7,
Section 5.13 is not warranted then.
2 Wiring
See Graphics, page 4.
Wire the LSN bases according to the lettering for LSN connection (5). During cabling, the
holders for cable ties (4) can be used to fix the base.
