Class X (DCLC) Device Loop Card
Installation Instructions
Model XDLC
INTRODUCTION The Model XDLC Device Loop Card from Siemens Industry,
Inc., is the interface for connection of Desigo Fire Safety
Modular/Cerberus PRO Modular smoke detectors, Multi-
Criteria detectors including Carbon Monoxide, manual
stations, monitor devices, and control devices to the Desigo
Fire Safety Modular/Cerberus PRO Modular System.The
XDLC uses one network address on the system.The
application program that is loaded into the on-board micro-
processor controls the XDLC operation.
The XDLC contains 16 LEDs for diagnosis of problems.
Ground fault detection is provided by the loop.
All field devices connected to the XDLC are addressed and
tested using the Device Programming Unit (DPU).
OPERATION The XDLC initializes, operates, and maintains all devices
residing on the loop.The XDLC communicates all relevant
device and event information, such as alarms and troubles,
to the PMI-2/PMI-3/OI-C/OI-D (PMI).The sensitivity of any
intelligent smoke detector can be checked and adjusted
from the PMI through the XDLC. All information about the
devices on the loop can be displayed on the PMI.The XDLC
allows the System polarity insensitive devices to be
connected without generating errors.
NOTE: PMI = PMI-2/PMI-3/FCM2041
The XDLC supports four Class A (DCLA) or Class X (DCLC)
loops (eight Class B [DCLB] parallel lines/stubs) of up to
252 Desigo Fire Safety Modular/Cerberus PRO Modular
intelligent field devices as well as device accessories (relay
bases, audible bases, and remote lamps) in any combina-
tion. The microprocessor controls the on-board isolators to
isolate any zone from the loop if one of them is shorted.
When one zone is isolated from the loop, the other zones
will still work.
The on-board microprocessor provides the XDLC with the
ability to function and initiate alarm conditions even if the
main PMI CPU fails.The XDLC accomplishes this “degrade” mode of operation by
monitoring the communications with the PMI. In the case of the failure of the PMI,

the XDLC continues to monitor its associated devices, and if any alarm device
activates, the XDLC will activate the outputs selected for “degrade” mode of operation.
Similarly, it will also signal other modules within its backplane as to the degrade alarm
condition. Note that output activation in degrade may take up to 60 seconds and that
outputs controlling releasing agents are not activated by “degrade” operation.
The “Degrade” mode operation is not the same as “Degraded Mode” as in ULC-
S527.
Controls and Indicators The front panel of the XDLC contains one reset switch, 16 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 re-initializes the XDLC operation.
The LEDs follow the reset switch and their functions are defined as follows:
POWER (Green) Normally ON. When illuminated, indi-
cates the power for the XDLC is applied
to the card. Blinks during firmware
download or if download has failed.
CARD FAIL (Yellow) Normally OFF. When illuminated, indi-
cates the card microprocessor has failed.
HNET (Yellow) Normally OFF. When illuminated, indi-
cates that the HNET communication with
the XDLC has terminated and the card
goes into degrade mode on HNET
failure.
GND FAULT (Yellow) Normally OFF. When illuminated, indi-
cates that the XDLC has detected either
a negative or positive ground fault on its
field wiring. Blinks during firmware
download.
ALARM (Red) Normally OFF. When illuminated, indicates
that the XDLC has detected an alarm.
TROUBLE (Yellow) Normally OFF. When illuminated, indi-
cates that the XDLC has detected a
trouble on its field wiring; or incapability
between firmware in either the PMI,
XDLC, or both.
OPEN Normally OFF. When illuminated, indi-
cates that the XDLC has detected an
open on its field wiring.
SHORT Normally OFF. When illuminated, indi-
cates that the XDLC has detected a
short on its field wiring.
LINE LEDS 1-8 Normally Off. When illuminated, indi-
cates a trouble (open or short) on the
associated line or loop.

Three rotary dial switches at the bottom of the front panel are used to set the HNET
network address of the XDLC. All field devices connected to the XDLC are ad-
dressed and tested using the Device Programming Unit (DPU). Refer to the DPU
Manual, P/N 315-033260 for further information.
PRE-INSTALLATION Set the three-digit HNET network address for the XDLC using the three rotary dial
switches located near the bottom of the front panel. (Refer to Figure 1 for the
location of the switches.) The address for the XDLC must be the same as the
address selected for it in the Zeus ProgrammingTool.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 dial to “2”, and set the pointer for the ONES dial to “3”. The range
of allowable addresses is from 001 to 251 (leading zeros must be used).
USB CONNECTOR
The USB connector provides an interface to download new Firmware to the XDLC.
Using a standard USB A-B cable connected to a PC running Zeus, a new XDLC
Firmware can be downloaded. The Zeus Configuration Program is used to select the
new Firmware and initiate the download to the XDLC.
Both the power LED and the Ground Fault LED will blink during download.The power
LED will blink alone if the firmware was not completely downloaded to the XDLC.
In addition to Firmware Download, the USB port provides a diagnostic log of the
XDLC internal functions for field support personnel.
INSTALLATION The XDLC 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 2.)
Insert the XDLC 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
card-cage are aligned properly.The card can only be
plugged into the card cage in one direction; 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 the card with the captive screws.

The XDLC circuit can be wired Class B (DCLB), Class A (DCLA), or Class X (DCLC).The
configuration tool allows selection of Class A, X or B. The XDLC field circuit wiring does
not require twisted, shielded wire, but is recommended. It can be installed in conduit
containing low voltage power, notification appliance circuits, audible and speaker zone
circuits, and RS-485 and other data circuits without restrictions.
Electrical connections for the zones are shown in Figure 4. The wiring style is set in
the Zeus Programming Tool without using external jumpers.
If the return wires in a zone are reversed (in a Class A [DCLA] configuration), the line
numbers and short LEDs associated with the affected zone will be illuminated.
Switch the two return wires to remove this trouble. Eliminate all other troubles
before completing the installation.
NOTE:
1. Devices wired as Class X (DCLC) must have Isolator Mode checked off.
2. For Class A (DCLA) and Class B (DCLB), the option for Isolation Mode is
available for the X-devices as long as the wiring matches the configuration.
3. During system initialization, the XDLC will test the wiring for each device
and produce “XDLC Device Wiring Mismatch” trouble if there is a mismatch
between the Isolation Mode in the configuration and the device wiring.
COMPATIBILITY 1. The XDLC supports compatible devices with the model numbers listed in
Table 1 for UL 864 and in Table 2 for UL2572. Use any combination of those
listed in Table 1 orTable 2, as applicable.
2. The XDLC supports a maximum of 252 Desigo Fire Safety Modular/
Cerberus PRO Modular intelligent field devices distributed across four Class
A (DCLA) loops or eight Class B (DCLB) loops. A mix of Class A (DCLA) and
Class B (DCLB) is supported. The XDLC supports a maximum of 190 Desigo
Fire Safety Modular/Cerberus PRO Modular intelligent field devices wired in
isolation mode distributed across four Class X (DCLC) loops. A mix of Class
A (DCLA) and Class X (DCLC) wiring is supported where the maximum total
number of devices across four loops is 252 with a limit of 190 of those
Desigo Fire Safety Modular/Cerberus PRO Modular intelligent field devices
wired in isolation mode.
3. All circuits are power limited to NFPA 70 per NEC 760. The XDLC supports
the use of 12-22 AWG non-shielded, twisted, thermoplastic fixture wire
without conduit, if permitted by local building codes.
4. No end of line device is required.
5. Total circuit resistance of each zone must not exceed 50 ohms. (Refer to
the chart on page 7.)
Maximum capacitance: 0.5μF between line+ and line-
1. 0 μF between line and chassis
6. T-tapping is not allowed on Class A (DCLA) or Class X (DCLC) loops.
7. All models are UL and ULC listed.
8. The Multi-Criteria detectors are programmed using the DPU. A PAD-5,
Document ID A6V101030358, or a SBGA-34 base, connected to a ZIC-4A, P/
N 500-033050, or ZIC-8B, P/N 500-648670, can be used to createTemporal
4 tones in conjunction with the Carbon Monoxide enabled detectors
FDOOTC441 or OOHC941. Using these detectors with the ABHW-4S or
ABHW-4B, the selection of tones are chosen using the panel’s configuration
tool.
