LIFT EMERGENCY TELEPHONES
Distance of the loudspeaker, microphone and buttons from the basic unit: 25 m max.
Buttons must not have a common return wire. To connect the basic electronics package with the user-interface
elements (loudspeaker, microphone and buttons) a shielded cable must be used. IY-ST-Y or AY-ST-Y. Connect
shield to –12 V terminal (see also Seite 2). Mount dial pad at a distance of 25 m max. (use Behnke patch cable
for connecting the dial pad).
In order to connect MLM A to C (microphone/loudspeaker modules = user units comprising loudspeaker, micro-
phone and button), you should use original Behnke patch cables – see also page 10.
The integrated add-on amplifier (1 W) can only be activated for MLM A. The corresponding configuration steps can
be found in our comprehensive technical manual (available as PDF on the Internet – see also note on page 2).
