INTRODUCTIONThe Model CDC-4 from Siemens Industry, Inc., is a card that
allows conventional detectors to be used on the FireFinder-XLS
system. It provides four Class A or Class B conventional detection zones. Each zone can support two-wire photoelectric or
ionization compatible smoke detectors and an unlimited number
of normally open circuit closure devices. The module also
supports Siemens Fire Safety flame and beam detectors. The
relay base, remote lamp and audible base may also be used with
the CDC-4. The CDC-4 uses one network address on the
FireFinder-XLS system. It has diagnostic LED indicators showing
module status and the status of each zone.
OPERATIONActivation of any device on the circuit initiates a zone alarm and
causes any previously programmed functions to operate. Any
circuit in an alarm or trouble condition is displayed on the PMI/
PMI-2/PMI-3.
The CDC-4 is designed to function in a local degrade mode
during failure of the FireFinder-XLS main processor or during
the loss of the system communication network. While in the
degrade mode, the CDC-4 can report both alarm and trouble
conditions and can activate local outputs on other modules
within the same enclosure.
The maximum zone alarm current can be set to either 175mA
or 100mA and is set in pairs for zones 1/2 and 3/4. When a
compatible detector is selected in the Zeus Programming Tool,
the maximum zone alarm current is automatically set by the
CDC-4. Detectors requiring the 100mA zone current limit (see
table on page 11) cannot be used on the same zone pair as
detectors requiring the 175mA zone current limit (see table on
pages 7-11).
CDC-4 zones may be configured either as alarm-causing or
supervisory-causing, if allowed by the local Authority Having
Jurisdiciton.
Do not use shorting devices on circuits with accessories on them. The shorting
devices will lower the zone voltage to a point where the accessories will not operate.

Any or all of the CDC-4 circuits may be programmed to operate with Alarm Verification. This allows the automatic verification of alarm conditions caused by smoke
detectors in order to prevent nuisance alarms. For further information, refer to the
FireFinder-XLS Manual, P/N 315-033744.
When upgrading the firmware in the CDC-4, be sure to check the PC board version.
Version 2.0 and above firmware are only compatible with PC board P/N 580-034888.
If version 2.0 or above firmware is uploaded into the older version of the CDC-4, the
PMI/PMI-2/PMI-3 displays “ROM SW Version Error”. The PC board revision number is
printed on the back of the CDC-4 board.
Controls and IndicatorsThe front panel of the CDC-4 contains one reset switch, sixteen LEDs, and three
HNET address switches as shown in Figure 1.
A reset switch is located on the top of the front panel. Pushing the reset switch reinitializes the CDC-4 operation (similar to a cold boot).
The LEDs follow the reset switch and their functions are defined as follows:
POWER(Green)Normally ON. When illuminated, indi-
cates that power for the CDC-4 is applied
to the card.
CARD FAIL(Yellow)Normally OFF. When illuminated, indi-
cates that the card microprocessor has
failed.
HNET FAIL(Yellow)Normally OFF. When illuminated, indi-
cates that the HNET communication with
the CDC-4 has terminated and the card
goes into degrade mode (applicable only
when card resides in the HNET network).
GND FAULT(Yellow)Normally OFF. When illuminated, indi-
cates that the CDC-4 has detected either
a negative or positive ground fault.
ZONE 1 ALARM(Red)Normally OFF. When illuminated indi-
cates that an alarm condition has been
detected in Zone 1. It will stay on
continuously until the system is reset.
ZONE 1 TROUBLE(Yellow)Normally OFF. When illuminated, indicates
that a trouble condition has been detected in Zone 1. It will stay on continuously until the condition is cleared.
ZONE 1 CLASS A OPEN(Yellow)Normally OFF. When illuminated, indi-
cates that there is a break in the Class A
wiring in Zone 1.
ZONE 2 ALARM(Red)Normally OFF. When illuminated indi-

cates that there is a break in the Class A
wiring in Zone 4.
Three rotary dial switches at the bottom of the front panel are used to set the HNET
network address of the CDC-4.
PRE-INSTALLATIONThe network address switches must be set prior to inserting the card into the CC-5
(refer to Figure 1):
Network Address Switches: Set the three-digit HNET network address for the
HUNDREDS
TENS
ONES
CDC-4 using the three rotary dial address switches located near the bottom of the
front panel. (Refer to Figure 1 for the location of the switches.) The address for the
CDC-4 must be the same as the address selected for it in the Zeus Programming
Tool. To set the address, turn the pointers on each of the three dials to the numbers
for the selected address. For example, if the address is 123, set the pointer for the
HUNDREDS dial to “1”, set the pointer for the TENS dials to “2”, and set the pointer
for the the ONES dial to “3”. The range of allowable addresses is from 001 to 251
(leading zeros must be used).

INSTALLATIONThe CDC-4 plugs perpendicularly into one slot in the CC-5 card-cage via two 96-pin
DIN connectors and can occupy any slot in the card cage. (Refer to Figure 4.)
Insert the CDC-4 card into the card guides rightside up
(lettering on the front panel is legible).
Slide the card in until the card edge connectors contact
the receptacles on the motherboard.
Verify that the DIN connectors of the card and the cardcage aligned properly. The card can only plug in one
direction to the card cage, if it does not align, DO NOT
FORCE the card.
Place thumbs on the front panel adjacent to the captive
screws and gently apply even pressure on the card until
the connectors seat in the receptacles on the
motherboard. Secure with the captive screws.
Power up the system and verify that the CDC-4 power
LED turns ON.
