3.40 HDCB Door Phone/Lock Control Box In-
stallation
3.41
The HDCB Door Phone Control Box sup-
ports three door phones (MDFB), or two door
phones and one door lock control. Wiring connec-
tions for the HDCB are the same as for an elec-
tronic telephone.
3.42 The overall combined length of the HDCB
and MDFB cable run from the KSU to the tele-
phone must not exceed 1,000 feet (305 M), if
using 24 AWG cable.
CA UT/ON!
When installing the HDCB or MDFB cable,
do not run parallel to and within 3 feet of
an ACpower line. AC power lines should
be crossed at right (90") angles only.
A void running the HDCB/MDFB wire pairs
near devices that generate electrical
noise, such as neon or fluorescent light
fixtures.
3.43 Refer to Wiring Diagrams, Section 200-096-
209, for wiring/interconnecting details. The fol-
lowing considerations should be made when in-
stalling door phones:
l
A maximum of four HDCBs are allowed per
I
system with PCTU(l, 2, or 3); three HDCBs are
allowed with PCTUS.
l
One electronic telephone (PEKU or PESU) port
(always the 5th circuit port) is required for each
HDCB.
l
HDCBs can only be connected to PEKU or
PESU port numbers 04, 12, 20, and 28.

Only one HDCB may be connected to a PEKU
or PESU.

will support an HDCB.
