Loudspeaker output
100 V or 70 V loudspeakers can be connected on each speaker output with the 4 (four) 12-pin
connectors that are delivered with the device. Loudspeaker cables with a cross sectional area
from 0.14 mm
Recommended connecting cable: stranded wire, LiY, 0.75 mm² (h/w 03/00 and higher).
About the cable diameter
The voltage drop over cables should not exceed 10 %.
Cables with a higher voltage drop lead to a high proportional cable attenuation at the
loudspeakers. This is particularly noticeable at higher volume levels, for example alarm signals.
A high voltage drop can also cause communication problems with the EOL modules.
The following table gives an overview of the maximum cable lengths for different speaker
loads depending on the cable diameters.

Maximum loudspeaker load
The maximum rated power should not exceed 500 W per amplifier channel and/or controller/
router output (see chapter 6.1.2.). The internal 2-in-6 router output block offers the possibility
to distribute the 500 W amplifier power to 6 zones. If two 500-watt amplifier channels are
used within a router cluster of 6 zones, up to 1000 W can be distributed to these 6 zones. The
maximum rated power of 500 W at a single speaker output must not be exceeded.
Danger!
It is possible that during operation shock hazard voltages (> 140 V peak value) may be
present at the outputs. Therefore, the connected loudspeaker zones have to be installed in
accordance with applicable safety regulations. When installing and operating 100 V
loudspeaker networks, compliance with the VDE regulation DIN VDE 0800 is mandatory.
Especially, when 100 V loudspeaker networks in alarm system applications are concerned, all
safety precautions have to be in accordance with the safety class 2 wiring.
