alarm report for ease in locating the source of the alarm. For fire fighters using the
system, standard NFPA Fire Service icons are presented to alert them to the availabil-
ity of fire service equipment (stand pipe locations, sprinklers, building fire hoses, fire
hydrants, etc.). Standard HazMat icons are also presented to notify responding
officials of possible hazards or people in that area of the building. Standard NFPA 704
Hazard rating icons can also be used.
The 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 alarms and troubles 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. The exception to this is when the XLS is configured as a
combined fire and mass notification system, in which case it can be configured to
allow fire emergency events to have priority over mass notification events or vice
versa.
The XNET and DNET networks allow connection of multiple FireFinder XLS panels
into a single networked system and provide support for the optional Global Voice
system.
The GCNET (Global Control Network) may be used to connect multiple XNET/DNET
networks (each called a “Building”) into a single network. GCNET provides Galactic
Voice Control across multiple Buildings from a single point, and provides support for
galactic display of Fire events via Management Stations. GCNET is carried on a single
Multimode or Single mode optical fiber.
The XLS Voice System with a ZAC-40 amplifier, when used in conjunction with
Siemens Hi-Fidelity speakers, meets the requirement for low frequency signal tone
as described in the section for Determination of Low Frequency Signal Format, in
UL464, Standard for Audible Signal Appliance, suitable for sleeping areas as required
by NFPA 72 Chapter 18.4.5 (2013 Edition). Refer to the Compatible Notification
Appliances list, P/N 315-096363, for compatible speakers.
