3.13 Cable Types and Calculations

3.13.1 General Requirements

The CIE cable type and cable installations shall follow the application related current standards and
regulations stipulated in AS/NZ 3000, AS/ACIF S-009 and AS1670.

3.13.2 Real Cable Resistance

The CIE cable length is mainly determined by the cable cumulated resistance. The cumulative cable
resistance is the total resistance of all installed copper wire used in the related circuit loop, including
both the supplying path and the returning path.

The cable resistance character is generally specified in ohms per meter by the cable manufacturer.
However, in the cable calculations, the real cable resistance shall be used, which includes the
following modifications of the manufacturer specified value.

1. The manufacturer specified value shall be doubled for twisted-pair cables.

2. The total cable length shall include both the supply path and the return path. The manufacturer

specified value shall be doubled for multiple core cable so that both the supply and the return paths
are considered.

For example, if the manufacturer specified cable resistance of a twisted pair cable is 0.05 Ohms per
meter, the real cable resistance per meter will be 0.05 X 2 X 2 = 0.2 Ohms per meter. If the cable
length is 100 meters, the cable cumulated resistance is 0.2 X 100 = 20 Ohms.

Some common used cable parameters are listed in the following table.

3.13.3 Zone, Audio Input and Monitored Switch Input

The zone, microphone audio input and monitored enable input cables are required to have less than
50

Ω of the total cumulated cable resistance.

The maximum cable length is calculated using the following equation.

L

MAX

= 50 / R

RPM

(Equation 1)

While

L

MAX

- the maximum cable length,

R

RPM

- the real resistance per metre.

For example, if the manufacturer specified cable resistance of a 2-core cable is 0.02

Ω per metre, the

real resistance will be 0.04

Ω per metre and the max. zone cable length will be 50/0.04 = 1250 metres.

3.13.4 Output Devices

For each speaker circuit cable length, please refer to the audio amplifier documentation.

For each dry-contact output, the cable length is determined by the connected equipment or devices.

For power output devices such as a MDH and or electronic sounders, the maximum cable length is
calculated using the following equation.

L
