5.5.2 HDSS Console Connections
The HDSS console must be connected to the data
pairs of circuits 7 and 8 on a PEKU with standard two-
pair twisted, jacketed telephone cable. To
accommodate the connection, the instrument end of
the HDSS console cable should be terminated in a
modular station connector block (RJ-ii). Refer to
Chapter 7-Wiring
Diagrams, for wiring/
interconnecting details. If using 24 AWG cable, the
overall length of the cable run from the Expansion Unit
(KSU) to the HDSS console must not exceed 500 feet
(152 meters). The HDSS console can operate with
either an electronic or digital telephone (preferably an
LCD model).
This section provides installation instructions for the
Digital Door Phone/Lock Control Units (DDCB or
HDCB). It also includes installation instructions for the
Door Phone (MDFB). Each DDCB or HDCB can
support as many as three MDFBs or two MDFBs and
one door lock.
The Strata DK280 system can be equipped with up to
12 MDFBs.
CAUTION!
When installing the HDSS console cable, do
not run the cables parallel if they are within 3
feet of an AC power line. AC power lines
should be crossed at right (90") angles only.
Avoid running HDSS console wire pairs near
devices that generate electrical noise, such as
DK280, DDCBs or HDCBs can only connect to slot
1 l/port 004, slot 12/pat-t 012, slot 13/part 020 and slot
14/part 028. DDCBs can only connect to circuit 5 (a
PDKU or RDSU PCB and HDCBs can connect only to
circuit 5 of a PEKU or PESU PCB).
Note:
DDCBs and HDCBs cannot connect to the
RSTU, PSTU.
