Model FCL2004-U1
MXL Device Interface Module
INTRODUCTION
The Model FCL2004 loop driver from Siemens Industry, Inc. is a module that allows MXL intelligent
addressable smoke detectors, manual stations, monitor devices, and control devices to interface to the
Desigo FC2025/2050, Cerberus PRO FC922/924 system. The application program that is loaded into
the on-board microprocessor controls the FCL2004 operation. A FC2025/2050, FC922/924 system can
support a maximum of 240 MXL intelligent field devices using up to two FCL2004 modules inside the
enclosure.
The FCL2004 contains eight diagnostic LEDs: Power, Card
Fail, Ground Fault, Degrade Alarm, Trouble, Loop Fault,
External Communications, and Firmware Update. Ground
fault detection of the intelligent loops is provided.
All field devices connected to the FCL2004 are addressed
and tested using the Device Programming Unit (DPU) or
the FPI-21 Programmer/Tester. The select system setting
on the DPU and FPI-32 must be set to MXL.

OPERATION
The FCL2004 initializes, operates, and maintains all devices residing on the loop. The FCL2004
communicates all relevant device and event information, such as alarms and troubles, to the
FC2025/2050, FC922/924 PMI. All information about the devices on the loop can be displayed on the
PMI.
The FCL2004 supports two separate Class A and B circuits of MXL intelligent field devices. Each
circuit can monitor and control up to 60 intelligent devices as well as device accessories (relay bases,
audible bases, and remote lamps) in any combination. The placement of the FCL2004 cards on the
adapter plate do not determine its address. The address is determined based on location in the cable
chain from the PMI. The FCL2004 directly connected to the PMI is always at address 91. If another
FCL2004 is added, the system will automatically address it to address 92. The on-board
microprocessor provides the FCL2004 with the ability to function and initiate alarm conditions even if
the Periboard/PMI fails.
