Device Loop Card
Installation Instructions
Model DLC
INTRODUCTION The Model DLC Device Loop Card from Siemens Industry,
Inc., is the interface for connection of FireFinder-XLS/Desigo
Fire Safety Modular/Cerberus PRO Modular smoke detec-
tors, Multi-Criteria detectors including Carbon Monoxide,
manual stations, monitor devices, and control devices to the
FireFinder-XLS/Desigo Fire Safety Modular/Cerberus PRO
Modular System. The DLC uses one network address on the
system. The application program that is loaded into the on-
board microprocessor controls the DLC operation.
The DLC contains 12 LEDs for diagnosis of problems.
Ground fault detection is provided by the loop.
All field devices connected to the DLC are addressed and
tested using the Device Programming Unit (DPU).
OPERATION The DLC initializes, operates, and maintains all devices
residing on the loop. The DLC communicates all relevant
device and event information, such as alarms and troubles,
to the System CPU. The sensitivity of any intelligent smoke
detector and the logic functions of any intelligent output
devices can be checked and adjusted from the Operator
Interface (OI) through the DLC. All information about the
devices on the loop can be displayed on the OI. The DLC
allows the System polarity insensitive devices to be
connected without generating errors.
The DLC supports only one loop (two isolated parallel
zones) of up to 252 FireFinder-XLS/Desigo Fire Safety
Modular/Cerberus PRO Modular intelligent field devices as
well as device accessories (relay bases, audible bases, and
remote lamps) in any combination. The microprocessor
controls the on-board isolator to isolate either zone from
the loop if one of them is shorted. When one zone is
isolated from the loop, the other zone will still work.
The on-board microprocessor provides the DLC with the
ability to function and initiate alarm conditions even if the
main FireFinder-XLS/Desigo Fire Safety Modular/Cerberus
PRO Modular CPU fails.
