MXL Line Card
Installation Instructions
Model MLC
INTRODUCTION
The Model MLC MXL Line Card 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 FireFinder-
XLS/Desigo Fire Safety Modular/Cerberus PRO Modular
System. The MLC uses two consecutive addresses on the
HNET network. The application program that is loaded into
the on-board microprocessor controls the MLC operation. An
XLS/Desigo Fire Safety Modular/Cerberus PRO Modular
system can support a maximum of 2500 MXL intelligent
field devices using up to 25 MLC cards.
The MLC contains nine diagnostic LEDs. Ground fault
detection is provided. A USB port is included to allow
firmware upload via the front panel.
All field devices connected to the MLC 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 MLC initializes, operates, and maintains all devices
residing on the loop. The MLC communicates all relevant
device and event information, such as alarms and troubles,
to the PMI/PMI-2/PMI-3 (XLS), FCM2041-U2 (Desigo Fire
Safety Modular), FCM2041-U3 (Cerberus PRO Modular).
The sensitivity of any intelligent smoke detector and the
logic functions of any intelligent output devices can be
checked and adjusted from the PMI/PMI-2/PMI-3 (XLS),
FCM2041-U2 (Desigo Fire Safety Modular), FCM2041-U3
(Cerberus PRO Modular) through the MLC. All information
about the devices on the loop can be displayed on the PMI/
PMI-2/PMI-3 (XLS), FCM2041-U2 (Desigo Fire Safety
Modular), FCM2041-U3 (Cerberus PRO Modular). To see
the available information for each device on the loop, refer
to the FireFinder-XLS IOM Manual, P/N 315-033744, the
Desigo Fire Safety Modular IOM, Document ID A6V11231620,
or the Cerberus PRO Modular IOM, Document ID A6V11231627.
The MLC supports two separate 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. Each circuit has a
separate address on the HNET network. The installer sets the address on the module
for the first circuit which can be either odd or even. A consecutive address is auto-
matically assigned to the second circuit internally.
