INSTALLATION NOTE MSS 30007
Fixing notes
The sounder base is designed for surface mounting and is provided for rear and surface cable
entry. The sounder insert has to be removed before fixing the mounting base. To release the
sounder insert, fixing clamps have to be pushed in direction of the arrows (Fig.2). for rear
cable entry, conduit box mounting, feedthe cable through the openings. For surface cable
feed, please break out the prepared cable entries. Install the mounting base with two screws
on a flat dry surface. Therefore, only the prepared fixing bores may be used (see Fig. 2)!

Tone table
The sounder provides 11 tones with an additional second toneoption (see table below). Tone
selection is via the integrated DIP switches. Volume setting follows infinitely variable via a
potentiometer. Both tones can be activated separately, whereby a subsequently activation of
the second tone switches off the first tone. Only if the sounder volume is set to the maximum
level, the certified sound (no. 1) comply with EN54-3. Certified sound measurements are listed
in Bulletin_Sound_Pressure_Level_EN54-3.pdf (F.01U.315.263). This document can be obtained
from the manufacturer.
