1.0 GENERAL DESCRIPTION
The DS 85 is designed to enforce (repeat) the
data stream in an intercom line (“string”) and to
supply additional 48V DC power to that intercom
line in case of long cable runs. For this purpose
the mini switch at the rear panel of the unit has to
be switched “on”. The 48V power is supplied to
pin 4 and 5 of the “Intercom Link Out” connector.
If it is not allowed that the intercom system has
powered intercom lines, the mini switch at the
rear panel of the DS 85 has to be switched “off”.
The DS 85 is now a data repeater only.
WARNING
:
The DS 85 may only be put in the
‘through intercom line’, so not in the CAT5/CAT6
cable between a user station and the “Intercom
Out” of a DS 80 Wall Box, nor in the cable
between a user station and one the “Intercom
Out” connectors of a DS 88 Hub.
The DS 85 has to be connected to a local mains
outlet (100 – 240 V AC, 50/60 Hz, 125 W).
Remotely switching the DS 85 on and off:
After a matrix unit in an digital intercom system is
switched on, it sends a handshake signal to its
intercom lines (strings) which triggers an
electronic switch inside the DS 85.
A triggered switch enables the power supply
section of the unit. As soon as a matrix unit is
switched off, the handshake signal disappears
from the intercom line and the DS 85 power
supply section switches off.
See the ASL Digital User Manual for safety
instructions and max. CAT5 cable lengths.
