This entry system is designed to utilize a building’s existing
telephone wiring and to address a variety of apartment entry
applications. Viking’s C-3000 Entry System provides secure
multi-tenant building access, without the need for any C.O.
lines; the only requirement is that each tenant have a touchtone telephone set wired to their apartment. Conversely, the
C-3000 performs equally as well in installations where C.O.
lines are present. An individual C-3000 module has a 12-tenant capacity; for larger applications, a maximum of eight (8)
C-3000 modules can be interconnected, allowing a total system capacity of up to 96 tenants. A C-3000 system consists of
at least one Master C-3000 module, and as many as seven
Slave modules.

From either of two entry doors, visitors may ring a tenant's telephone with a distinctive cadence, alerting
the tenant of their arrival. The C-3000 provides call waiting tones if the tenant’s line is in use. The tenant
may then converse freely with the visitor via their existing telephones. Once identified, the tenant can
elect to allow the visitor entry, by entering a single touch-tone on the keypad of the tenant's telephone set.
The C-3000 keyless entry feature supports unique entry codes for each tenant. As a measure of securi-

ty, the codes can be easily changed as
tenants move in and out of the building.
A postal lock feature is also supplied as
an added convenience.

A. Definitions
Master Module: The C-3000 module assigned module ID #1. Also, the only module in a single-module system.
Slave Module(s): Any module(s) in addition to the Master, in a multi-module C-3000 system. Slave modules are
assigned module ID numbers in the range of #2 through #8.
“66” Punchdown Terminal Block: A connection peripheral used to interface telephone lines easily. This installation
requires a “split” punchdown block.
B. Preparing the Installation
Select an appropriate location in which to install the C-3000 System. It is normally most convenient to install the C-3000
modules as near as possible to the telco demarcation point; that is, the common point at which all tenant phone lines
enter the building (if applicable). If the tenant phone wiring is not currently cabled though a "66" block or blocks, it will
be necessary to install "66" block(s) at this time to facilitate the installation of the C-3000 system. Note: See the instal-
lation diagram on the following page for recommendations on which “66” block to use.
C. Assigning Module ID Numbers
A C-3000 system consists of at least one (Master) C-3000 module, and as many as seven (7) Slave modules. Multiple
C-3000 modules are all interconnected from module to module, using the supplied modular cords, connecting the
MULTI-MODULE INTERCONNECTS from IN to OUT. If more than one C-3000 module is being installed, it will be necessary to set module ID numbers at this time. Each C-3000 module must have it's own ID number to be part of a C-
3000 system. Module ID numbers are set using the three-position DIP switches on the front of the C-3000 modules
(see diagram below). Module ID numbers are used to determine which C-3000 module is responsible for handling a
particular range of apartment numbers. As an example, Module #1 (the Master module) handles apartment numbers 112, Module #2 handles apartment numbers 13-24 and so forth.
D. Wiring Table
Refer to the wiring table below when installing the cabling for the C-3000 system. Note that tenant line 1 enters on pins
1 & 26 of the RJ-21X connector, and exits on pins 2 & 27 of the same connector. This also means a visitor would dial
a touch tone 1 to call the tenant connected to line 1. This scheme is used on all 12 lines on the RJ-21X connector,
occupying all pins up thorough the pin 24 & 49 pair, and repeats on up to the 96th tenant on the
8th module. The last pair on the RJ-21X connector (pins 25 & 50) has a special function. This
last pair is used (on the Master module only) as a connection for the Building Manager's
Programming Phone.
