6 Cables and Connectors

6.1 Introduction

Each Zeus intercom system will have unique requirements

for cables, so it is not practical to supply these with Zeus.

A computer interconnect cable has been provided, but

even this may not be long enough for your system layout

requirements. Most cables will need to be custom built.

Following is some useful general information for those

who are not familiar with cable construction. Connection

diagrams are also included for all of the common types of

connections to Zeus.

6.2 Connectors

6.2.1 Types, Solder vs Solderless

Connectors for cables are of two general types: solder and

solderless. Solder connectors are the least expensive, and

the connections are repairable. However, there is more la-

bor involved when using these connectors, and some sol-

dering skill is required to make good connections.

Solderless connectors are generally much more expensive

and require special tools, which can also be expensive.

Also, the connections are not generally repairable (except

that you could probably perform solder repairs if needed).

On the other hand, cable construction is quicker with

solderless connectors. Ask your intercom dealer about

recommended sources for connectors.

6.2.2 Pin Numbers

Pin numbers are generally stamped on the connectors, but

the numbers are very small. It helps if you know that the

connectors you will be using generally follow a standard

numbering sequence, with the male and female connec-

tors having mirror-image numbering. See Figure

6.3 Cable Requirements

We recommend 22AWG, stranded, twisted pair cable for

your connections. For most applications you can use un-

shielded cable. Shielded cable is only required when some

condition in the environment is inducing noise into the in-

tercom system. For keypanels and the TIF-951, the cables

should have three twisted pairs. To connect 4-wire audio

devices, you’ll need two twisted pairs. To connect single

audio inputs or outputs, such as program inputs or paging

speaker outputs, you’ll need one twisted pair. The LCP-102

and the UIO-256 require a single twisted pair. Ask your in-

tercom dealer about recommended sources for cabling.
