hazards or people in that area of the building. Standard NFPA 704 Hazard rating icons
can also be used.
The 32-bit microprocessor CPU at the heart of FireFinder-XLS rapidly processes
logical decisions based on the status of the smoke detection and other initiating
devices to control the system outputs. The object oriented software configuration
tool, Zeus, is used to configure the FireFinder-XLS system’s operation based on the
customer specified operating requirements.
The System continuously checks all software and hardware for proper operation. It
checks all System memory components, control panel electronic hardware, and the
System program. A hardware watchdog circuit is provided to ensure that System
programs are functioning properly. If a problem develops with the program or proces-
sor, the watchdog circuit places the System into a trouble condition and resets it.
Each module in the FireFinder-XLS System has its own microprocessor. To ensure
reliable operation, if the main panel’s central processing unit stops, these modules,
operating in degrade, still annunciate any alarm or trouble through common lines
called Any Alarm and Any Trouble. All of the modules communicate with the main
FireFinder-XLS central processor through an RS-485 network communications
system.
While FireFinder-XLS is designed for multiple applications, such as security point
monitoring, the fire alarm operation is always processed as the highest priority over
all other operating modes.
CONFIGURATION The table below presents the minimum configuration necessary to meet NFPA 72
Local, Municipal Tie, Remote Station, Proprietary and Central Station, UL 1076, and
NFPA 12A, 13 and 2001.
