NOTE: * These modules draw current from the Combus to power devices

external to the module. This current must be added to the total Combus

current. See manufacturer’s specifications for the current draw of each

device. Each LED assembly draws up to 20mA of current.

Combus Operation and Wiring

The Combus is used by the control panel and the modules to

communicate with each other. When the PC4204CX is used to repower

and extend the Combus, please refer to the wiring diagram for the

exact wiring procedure.

NOTE: Please follow the dia ram exactly.

Modules can be home-run, connected in a daisy chain or T-tapped

anywhere on the Combus.

The following rules MUST be followed when wiring the Combus:

1.1.

1. The Combus must be run in minimum 22-gauge wire.

2.2.

2. No module can be more than 1000' (305m) in cable length from

the PC4204CX.

3.3.

3. Shielded wire should only be used in areas that present excessive

RF noise or electromagnetic interference. If shielded wire is used,

the maximum distance a module can be located from the

PC4204CX is significantly reduced. Check the capacitance rating

of the wire to calculate the maximum distance (see “Capacitance

Limits”). NOTE: Shielded wire is not recommended.

4.4.

4. The total capacitance of the Combus wiring must not exceed 80nF

between the control panel and PC4204CX module or between two

PC4204CX modules (see “Capacitance Limits” below).

Long Distance Combus Extensions

The length of Combus from a PC4204CX Combus Regenerator can

be extended beyond 1000ft (305m), providing the following

conditions are met:

• Combus must be regenerated and repowered at both ends of

the wire run using the PC4204CX.

• No other modules are to be connected along the long distance

wire run.

• A maximum distance of 4000ft (1220m) can be achieved between

two PC4204CX devices. To extend further, additional PC4204CX

devices should be used.

NOTE: The wirin used to connect this equipment must be insulated with

PVC, TFE, PTFE, FEP, neoprene or polymide.

When extending Combus long distances, use the following chart to

determine what gauge of wire is necessary:

Maximum Length AWG

2000ft (600m) 22

3000ft (900m) 21

4000ft (1200m) 20

Line Loss

When current is drawn through a piece of wire, voltage will be lost

due to the wire’s resistance. This voltage loss must be considered

for all installations.

To ensure proper operation, at least 12.5VDC must be applied to all

modules on the system (when AC is applied and the battery is fully

charged). If less than 12.5VDC is applied, system operation will be

adversely affected.

To correct the problem, try any or all of the following:

1. Connect another PC4204CX power supply near the module to

provide power to the Combus.

2. Reduce the length of the Combus run to the module.

3. Increase the gauge of wire.

Capacitance Limits

An increase in capacitance on the Combus will affect data

transmission and will cause the system to slow down. Capacitance

will increase for every foot of wire added to the Combus. The

capacitance rating of the wire used will determine the maximum

length of the Combus, between two PC4204CX Combus Repower/

Regenerator modules.

For example, 22-gauge, non-shielded, 4-conductor wire has a typical

capacitance rating of 20 picofarads per foot (which is 20nF/1000’).

For every 1000' of wire added – regardless of where it is run – the

capacitance of the Combus will increase by 20nF.

The following chart indicates the total Combus wire allowed

depending on the capacitance rating of the wire used:

Wire Capacitance per

1000’( 00m)

TOTAL Combu s Wire

Length

15nF 5300’/1616m

20nF 4000’/1220m

25nF 32 00’/976m

30nF 26 66’/810m

35nF 22 80’/693m

40nF 20 00’/608m

Wires run in parallel also increase Combus capacitance. For example,

when using 20nF wire, the following would be some of the

combinations allowed:

• Four wire runs at 1000'/305m each

• Six wire runs at 666'/203m each

• Eight wire runs at 500'/152m each

• 10 wire runs at 400'/122m each etc…

Contact the wire manufacturer for the capacitance ratings of the

wire being used.

3.4 Regenerating Combus

This module will regenerate the Combus signal as it passes from

one side to the other. The LEDs on the module will illuminate

whenever there is activity on either side of the input or output of

the module.

LED 1 LED 1

LED 1 illuminates when the module transmits data on ‘Combus In’

LED 2 LED 2

LED 2 illuminates when the module transmits data on ‘Combus ut’

The PC4204CX module will isolate ‘Combus In’ from any short

circuit problems on ‘Combus ut’. In the event of a problem, the

PC4204CX module will generate a module fault along with the

modules on the disabled Combus. This information can be used

to determine which section of Combus is disabled on the system.

When connecting the PC4204CX to the Combus, care must be taken

to ensure that the ‘Combus In’ terminals are connected to the

wires originating from the control panel (or a module that may be

situated between the PC4204CX and the control panel).

3.5 Applying Power

NOTE: Do not connect power until all wirin is complete.

After all wiring is completed, apply power to the control panel.

Connect the battery leads to the battery, then connect the AC

transformer. Then, connect power to the PC4204CX: first connect

the battery leads, then the AC transformer.

For more information on control panel power specifications, see

the control panel

Installation Manual

NOTE: It is the installer’s responsibility to provide adequate protection

for the transformer used in the primary and secondary circuit accordin

to the rated current of the transformer. The transformer used must be Class2,

Fail Safe as defined within EN61558-1 and must meet the applicable

requirements of the EN60950 Standard. A readily accessible disconnect

device must be incorporated into the fixed wirin and must disconnect

both poles simultaneously. The wirin connected to the PC4204CX must

be mechanically protected, routed, supported, clamped or secured in a

manner that prevents excessive strain on wire and terminal connections,
