PC4204CXCF
Power Supply / Relay Output / Combus Repeater Module
v 3.0 • Installation Instructions
®
1.0 Introduction
The PC4204CXCF is a power supply/relay output module for use
with PC4010CF and PC4020CF Maxsys fire/security systems. The
PC4204CXCF provides one power output for system devices and 4
programmable relay outputs. Relay 1 can be used to repower the
Combus. This module will also regenerate the Combus data signal to
allow for longer wire runs. This module is not to be used for fire alarm
bells.

NOTE:NOTE:
NOTE: The PC4204CXCF is the only power supply which can repower the
Combus on PC4010/PC4020CF systems. See the control panel
Installation
Manual for details.
The PC4204CXCF is the only power supply unit for PC4010CF/PC4020CF
system devices which has UL/NFPArequired supervision integrated
into the control panel. Primary power for the PC4204CXCF must be
connected to the same branch circuit as the PC4020CF.

3. Press the circuit board onto the plastic standoffs to secure the
module to the cabinet.
Once the unit is mounted, wiring may be completed.
3.3 Installation and Wiring
NOTE: The PC4204CXCF is intended to be PERMANENTLY
CONNECTED and should be installed by service personnel only.
Before beginning to wire the unit, ensure that all power (AC
transformer and battery) is disconnected from the control panel.
Perform the following steps to complete wiring:
1. Connect the four panel-originating Combus wires to the
PC4204CXCF. Connect the red, black, yellow and green Combus
wires to the RED, BLK, YEL and GRN Combus In terminals,
respectively.
If Relay 1 is being used for Combus power, connect the Combus
wires according to the diagram below. Note that for this option,
jumper Con3 must also be set for “Repower Relay 1.”
Additional modules repowered by the PC4204CXCF should have
the black, yellow and green Combus wires connected to the BLK,
YEL and GRN Combus Out terminals respectively.
2. Complete all output wiring.
3. Connect the external tamper switch, if used.
Consult the wiring diagrams for further information.

Current Ratings
In order for the system to operate properly, the power output of the
PC4204CXCF module cannot be exceeded. For the maximum available
AUX current, refer to the Battery Selection Charts based on 24h/60h
standby power time. The maximum available AUX supply current is
dependent on the size of the transformer used as well as the selected
battery charge current. Use jumper J2 to control the supply current
(see below).

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.
1.1.
1. The Combus must be run in minimum 18-gauge wire.
2.2.
2.2.
2. No module can be more than 1000' (305m) in cable length from
the PC4204CXCF (see below ‘Combus Extensions’).
3.3.
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.
4.4.
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 1LED 1
LED 1 illuminates when the module transmits data on ‘Combus In’
LED 2LED 2
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.

IMPORTANT: A minimum of 1/4" (6.4mm) separation
must be maintained at all points between power limited
wiring and all other non-power limited wiring and
connections. Wire entry for power limited wiring must
be separate from non-power limited wiring.
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 according 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 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.
