The required 2-pole connection cable (max. 50 m, > 2 x 0.5 mm²) is not enclosed. The loudspeaker must be mounted in such a manner that it will be protected against water (e.g. under a roof overhang). A light-emitting diode indicates the function. The cable connection is made via a 2-pole terminal under the slide cover of the additional loudspeaker. The additional loudspeaker must be mounted in such a manner that it may radiate freely and without obstacles onto the surface to be protected.
