Supply Voltage - Dynacord Promatrix 6000 Operation Manual

Promatrix 6000 Router
The audio outputs on the device allow to connect 100 V (or 70 V) loudspeaker zones. The
delivery includes 12-pin connectors. Conductor cross-sections of 0.14 mm² (AWG26) to
1.5 mm² (AWG16) can be used.
Recommended connecting cable: flexible CU strand, LiY, 0.75 mm².
For ease of installation, the connector can be removed. Several loudspeakers can be
connected until the point at which the total power consumption of the loudspeaker network
corresponds to the nominal power value of the amplifier channel, where the rated load
resistance of the power amplifier outputs is not to be exceeded. The nominal power values
and the rated load resistances of the outputs can be found in the documentation of the power
amplifier.
Notice!
Conductor cross-section
The maximum voltage drop must be less than 10% to avoid alarm signal attenuation and
ensure a sufficient signal level of the pilot tone for (optional) EOL modules.
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 3 standard.

Supply voltage

Connect a 24-volt DC source to the DC power input. The delivery includes a 2-pin connector.
Conductor cross-sections of 0.2 mm² (AWG24) to 6 mm² (AWG10) can be used.
Recommended connecting cable: flexible CU strand, LiY, 4 mm².
The DC input is protected against incorrect polarity and overload. The associated fuse is
located on the inside of the device and is not accessible from outside of the device.
Warning!
!
Never connect the positive terminal + with ground.
