each MDF block; attach them to the
side opposite the iV1STU cable. Use
bridging clips to connect the MSTU
cable pairs to the station cable pairs.
07 .12
The cables used for station
wiring should be industry-standard quad
or twisted pair.
07 .13 The overall length of the
cable run must not exceed
1000
ft. for
24 AWG wire.
WARNING:
When installing station ca-
ble, do not run parallel to
and within 3 ft. of an AC
power
line; any
power
lines
should be crossed
at
right
angles (90°) only.
07.14 At the station locations, ter-
minate the station cable in a conven-
tional 4- or 6-conductor modular station
connector to accommodate the modular
line cord from the
EK
T. The standard
modular EKT cord length is 7 ft., while
the maximum allowed length is 25 ft.
07 .15 Figures 14 and 15 show the
EKT wiring arrangement.
07 .16
The various manufacturers of
modular station blocks have employed
different color codes to indicate the
sequence of pairs in their blocks.
However, the color code most commonly
used is shown in Figures 14 and 15.
Verify the configuration of your modu-
lar blocks before connecting the station
cables.
07 .20 Intercom Code Assignment
07 .21
Intercom codes are assigned
permanently to specific MSTU cable ap-
pearances in STRATA VI. Make sure
the station cables are connected to the
proper terminals (Figures 14 and 15).
