capacity only by the fire alarm panels. The Xenta 401, or
other programmable Xenta controller, will typically be
used as a Fire Alarm Managing Controller(s) – FAMC.
Regardless of contact or serial alarm input from the
FSSI, the FAMC will programmed to trigger the
automated zoned fire/smoke response based on only the
first alarm signal and will ignore subsequent alarms until
manually reset from the FSCS. The FAMC will insure the
applicable zone controllers receive the fire alarm signal.
The FSCS-Managing Controller (FSCS-MC) will typically
be programmed to enunciate the alarm condition on the
FSCS panel.
RS232 Simplex Interface
The FSSI provides the Simplex interface via an RS232
serial port positioned on the side of the enclosure. The
RS232 port is presented through an RJ45 modular jack.
The FSSI-U8 (Field Server Simplex Interface) is UL
Listed (UL864) for application in a TAC Smoke Control
System. This data sheet provides information,
instructions and restrictions pertaining to the proper
application of this specific product in a smoke control
system. This data sheet takes precedence over other
general product installation and application information
for the FSSI and must be used in conjunction with the
“Smoke Control Systems Manual” (0-004-7897-1). The
manual provides a system level view of the smoke
control application and provides additional information
regarding the various products that can be
interconnected to form a system.
General Application
The TAC model FSSI-U8 is a UL864 listed version of the
FieldServer Technologies’ Model FS-B2011-01 Simplex
LON Bridge product. The FSSI is a protocol translator
gateway between the industry standard LonWorks
technology LON network and the proprietary Simplex
Within the TAC smoke control system, the FSSI may be
used to serially receive fire and smoke alarm signals
from a Simplex fire alarm panel. The FSSI supports
Simples series 4020, 4100 and 4100U fire alarms
The fire alarm signals used to activate the system’s
automated zoned smoke control response may originate
from any UL864 listed system via discrete contact
closure which can be monitored by any of the Xenta
controllers. However, when working with a large system,
receiving the fire alarms through a serial interface such
as the FSSI can be much more efficient and limited in
An RJ45 modular Cat-5 cable (such as provided with the
FSSI Simplex I/F) extends from the RJ45 RS232 port on
the FSSI to the Simplex fire panel. The FSSI cable is
terminated with the serial data connections at the
Simplex panel. Refer to the Simplex installation
documentation for RS232 connection description.
The RS232 RJ45 jack provides two integral LED
indicators which illuminate to indicate activity on the
RS232 transmit and receive signals. The yellow LED
indicates transmission from the FSSI and the green LED
indicates receive data to the FSSI.
The integrity of the RS232 Type-3 communications
between the FSSI and the Simplex panel is supervised
by the FSSI. Upon the detection of a fault, the FSSI shall
communicate the condition to the FSCS-MC to audibly
and visually enunciate on the FSCS panel.
The RS232 connection to the Simplex panel must not be
longer than 20 ft. in length and must be run in conduit.
The RS232 is power limited (+-12V).
Three conductors (1, 4 & 8) of the 8-position RJ45
modular jack on FSSI are connected to Simplex as
FSSI RJ45 receptacle is numbered 1-8 right-to-left.

Controller Network LON Communications
The FSSI controllers communicate with the Xenta
controllers using a common network, LonWorks TP/FT10, 78Kbps LON (Local Operating Network).
Rating: Type 3, Max: 5V, .1A, Power Limited,
8850ft @ 16awg cable. See smoke control system
manual for table of cable and distance specifications.
The LON port is presented on the side of the FSSI
enclosure with a two position plug-on terminal block
labeled “Fieldbus”.
The LON communications is Power Limited and should
be supervised from the FSCS controller.
The FSSI is housed within a metal enclosure (4.08”W x
3.82”D x 1.7”H) and provides rails along the side with
holes for panel mounting. The FSSI should be installed
within one of the ENCL-.. series enclosures designated
in the smoke control system manual.
Operating Environment
LON Network Integrity
In smoke control applications, the LON network
communications cable carrying smoke control
commands may only interconnect with products that are
UL864 listed. The smoke control system manual
identifies the other TAC and 3rd party products that may
be interconnected in the smoke control system on the
LON with the FSSI.
The communications integrity to the FSSI from the
FAMC is supervised and any fault is reported to the
FSCS controller for audible and visual enunciation on
the FSCS panel.
