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 PC4204CXCF is used to

repower the Combus, please refer to the wiring diagram for the exact

wiring procedures. Note: Please follow the diagram 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 18-gauge wire.

2.2.

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

the PC4204CXCF (see below ‘Combus Extensions’).

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

PC4204CXCF is significantly reduced. Check the capacitance rating

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

Limits” below). 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 PC4204CXCF module or between

two PC4204CXCF modules (see “Capacitance Limits” below).

Long Distance Combus Extensions

The length of Combus from a PC4204CXCF Combus Regenerator can

be extended beyond 1000’, providing the following conditions are met:

• Combus must be regenerated and repowered at both ends of the wire

run using PC4204CXCF and modules.

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

• A maximum distance of 4000’ can be achieved between two

PC4204CXCF devices. To extend further, additional PC4204CXCF

devices should be used.

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

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

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 PC4204CXCF 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 PC4204CXCF Combus Repower/Regenerator modules.

The following chart indicates the total Combus wire allowed depending

on the capacitance rating of the wire used:

Wire Capacitance per

1000’(300m)

TOTAL Combu s Wire

Length

15nF 5300’/1616m

20nF 4000’/1220m

2 5n F 32 00’ /97 6m

3 0n F 26 66’ /81 0m

3 5n F 22 80’ /69 3m

4 0n F 20 00’ /60 8m

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 ouput of the module.

LED 1LED 1

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

LED 2LED 2

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

The PC4204CXCF module will isolate ‘Combus In’ from any short

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

PC4204CXCF 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 PC4204CXCF 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 PC4204CXCF and the control panel).

3.5 Applying Power

NOTE: Do not connect power until all wiring 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 PC4204CXCF: first connect

the battery leads, then the AC transformer.

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 wiring and should disconnect both poles

simultaneously. The wiring connected to the PC4204CXCF must be

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

that prevents excessive strain on wire and terminal connections, loosening of

terminal connections and conductor insulation damage.

NOTE: Do not connect fully discharged (less than 10V) or damaged batteries

to the PC4204CXCF.
