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, feed the 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)!
