2 Lettering for conventional
connection
3 Long slit
4 Triangular mark
5 Single guideway
*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.
Connection
See Figure 1, Page 3 to Figure 3, Page 3.
Wire the base according to the lettering for GLT connection (2). During
cabling, the holders for cable ties (1) can be used to fix the base.
