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,
