GENERAL
The intent of this manual is to guide field installation
and test personnel through the installation and set-up of the
Compact CEC and C3 Maestro portions of the C3
Advantage dispatch system. Detailed installation and power-
up procedures are included in this manual for the Compact
CEC.
To avoid duplication of set-up and troubleshooting
documentation, the CEC/IMC Digital Audio Switch –
Installation, Set-Up and Troubleshooting manual,
LBI-38938, has been included with this manual set.
References to the applicable set-up sections within
LBI-38938 which also apply to the Compact CEC are made
in the set-up portions of this manual. If necessary, also refer
to LBI-38938 for troubleshooting information.
Also to avoid documentation duplication, references are
made to the installation and set-up information in the C3
Maestro Console System maintenance manuals, LBI-39062
and LBI-39100 (sub-manuals LBI-39055 and LBI-39101
respectively) and to the C3 Maestro Console System –
Editor Program user's manual, LBI-39056. These manuals
are provided with the C3 Maestro dispatch console
equipment package.
NOTE
Unless otherwise noted, all installation, power-up,
and set-up procedures in this manual should be
performed in the order presented.
COMPACT CEC INSTALLATION
FLOOR PLAN
In a standard C3 Advantage dispatch system
installation, the C3 Maestro consoles are co-located with the
Compact CEC cabinet. In an installation of this type, the
consoles may be located in the same room as the Compact
CEC or they may be located in an adjacent or nearby room.
The pre-wired console-to-Compact CEC cables supplied
with the C3 Advantage package are 100 feet (30.5 meters) in
length. If longer cabling is required, the cables should not be
lengthened to exceed 4000 feet (1219 meters). This is the
specified limit for an RS-422 serial interface.
Alternately, one or more C3 Maestro consoles may be
remotely located via dedicated phone line (or equivalent)
interconnections. In this case, modem and/or microwave
equipment floor plan provisions must be made at the
Compact CEC location if this equipment is not installed in
the Compact CEC cabinet. In addition, floor plan provisions
for the modem and/or microwave equipment must also be
made at the C3 Maestro console's location.
Three (3) punch blocks within the Compact CEC
cabinet are mounted on a punch block mounting rack. These
punch blocks provide the line audio and control data
interconnect points for the external equipment such as the
C3 Maestro consoles and the EDACS trunked site. The
mounting rack is secured to the cabinet's rear horizontal
mounting rails just above the RPS unit.
In some cases, it may be beneficial to remove this
mounting rack/punch block assembly from the Compact
CEC cabinet and place the assembly at another location such
as on a nearby wall or within an existing punch block
cabinet. If relocated, floor plan provisions should be made
for the punch blocks. The five (5) factory-supplied Telco
cables which interconnect the Compact CEC's Concentrator
Cards (A1 thru A3) to its punch blocks (PB1 thru PB3
respectively) are 15 feet (4.57 meters) long. Therefore, if
using the factory-supplied Telco cables, the maximum punch
block relocation distance from the Compact CEC is limited
to approximately 15 feet minus any horizontal rise and fall
required for cable ducts, trays, etc. In the Compact CEC
cabinet, the Concentrator Cards are approximately 4.4 feet
(1.34 meters) from the floor. If longer or shorter Telco
cables are required, see Table 1 for part number
information.
Cabinets which contain any optional equipment ordered
or planned for the installation should also be included on the
original floor plan. Optional equipment includes items such
as logging recorders, Call Director patch equipment and
UPS equipment.
EQUIPMENT ROOM GROUNDING
❏
Installation manual LBI-39067 – Standard For Site
Grounding And Protection – is included with this
set of manuals. Refer to LBI-39067 for proper
grounding techniques. These techniques should be
observed in order to protect the equipment and
service personnel from lightning and other sources
of electrical surges.
AC POWER AND UPS EQUIPMENT
The Compact CEC employs a Redundant Power Supply
(RPS) unit which is mounted at the very bottom of the
cabinet. This power supply unit incorporates dual (2)
independent switching power supply modules which each
have an ac power input (120 or 230 Vac nominal) and +5,
+15 and -15 Vdc outputs. "ORing" diodes inside the RPS
unit combine matching dc outputs from each module before
application to the Backplanes and the uplink GETC. With
