Urmet Kombi Push Button Panel Audio Unit
Amplified Micro Loudspeaker for Urmet Kombi Push Button Panels
This door speaker is compatible with Urmet' s Kombi series pushbutton panels, which use conventional 4+N system technology with electronic and traditional call. The amplified micro-speaker and the modules with integrated electronics 825/220 and 825/320 allow the amplifications to be adjusted in both directions by means of two potentiometers.
To adjust the volume of the inner or outer potentiometer, simply move the potentiometer to the right to increase the volume and to the left to decrease the volume. Its transmission values are calibrated to their optimum values.
The phonic unit has to be inserted into the prepared place in the Kombi modules for micro loudspeakers by screwing it to the columns.
