This control unit must be installed with compatible initiating devices (smoke detectors, etc.) and
notification devices (horn, lights, etc.) connected to it. Electrical ratings of the initiation and notification
appliances must be compatible with the electrical ratings of the control unit and must be properly
interconnected. The wiring used for interconnection must be large enough to carry the total current for all
appliances without excessive voltage drop.
The control unit must be connected to a dedicated primary electrical source that has a high degree of
reliability and adequate capacity for this control unit. The only means of disconnecting this power source
shall be available only to authorized personnel and clearly marked "Fire Alarm Circuit Control".
The control unit must also have connected to it a battery set (24v) that has enough capacity to properly
operate the system for 24 or 60 (depending on system type) hours standby and 5 minutes alarm per
NFPA 72 (chapter 1). These batteries do lose capacity with age. Batteries must be replaced when they
fail to provide the control unit with the required standby and alarm power or after 4 years, whichever
happens first. These batteries must be checked for performance at least two (2) times a year or more
often if local requirements dictate.
Fire alarm control units cannot last forever. Even though this control unit was made to last for the
expected life of the fire alarm system, any part could fail at any time. Therefore a regular test program
should be followed and documented to make sure that each part of the system is tested as in Chapter 7
of NFPA 72 or more often if dictated by local code requirements. Malfunctioning units must be replaced
or repaired immediately by factory authorized service personnel.
NOTE: This control unit is designed to show an alarm condition when the
initiating devices connected to it detect specific conditions. These conditions
may or may not represent a life-threatening condition. Also, evacuation of a
building or area unnecessarily may subject individuals to an unnecessary
hazard. Therefore, it is most important that the building owner, manager, or
representative promulgate, distribute, and/or post instructions describing
steps to be taken when the fire alarm control unit signals any alarm condition.
These instructions should be developed in cooperation and conformance with
representatives of the local authority having jurisdiction.
As a backup or precautionary measure, it is strongly suggested that one of these steps should be to notify
the local fire department of an abnormal condition even where the DACT option (or similar device) is
included in the system.
Along with the use of this instruction manual, the appropriate following standards and the manufacturer's
instructions for initiating and notification devices should be used to install and maintain a functioning fire
alarm signaling system.

unit can address up to 8 FS-RU Serial Relay Units and/or FS-SAU Serial Annunciator Units. Auxiliary
power supplies will be required to power units beyond the control unit capability.
ADDRESSABLE DEVICES
Siemens Addressable Detectors
The control unit processor sends the sensitivity and pre-alarm settings to the detectors and polls the
detectors as to their status. The detector determines normal, trouble, pre-alarm or alarm conditions and
relays the status to the control unit.
Variable Thresholds
The obscuration level for alarm can be adjusted from the control unit on a permanent or time-variable
basis. This facility also means that the control unit can display information on individual points for
maintenance or service.
The control unit can trigger an alarm or trouble automatically on the occurrence of a number of conditions
of the detector. These include:
• Maintenance alert
• Pre-alarm alert
• No response
• Incorrect response
Other Siemens Addressable Devices
Heat Detectors
Addressable heat sensing detectors may be intermixed on the circuit for locations where heat sensing
may be the most effective detection mode.
Addressable Modules (Monitor and Control)
In addition to detectors, the circuit can communicate with addressable modules, allowing initiating devices
or notification appliances with local power sources, and supervising the power sources.
Manual Stations
Addressable manual stations may be intermixed on the circuit with proper response programmed into the
control unit.
PROCESSOR CONTROLLED OUTPUT ZONES
While the notification appliance circuits are essentially hardware circuits, the fact that the outputs are
commanded and controlled by the processor does provide more versatility than in a total hardware
system. All functional selections are included in the control unit programming process.
Output Sounding Patterns
The notification appliance circuits are operable in different sounding patterns. Any circuit is selectable to
any of eight software-generated patterns or continuous sounding. For convenience, three of the patterns
are preprogrammed for March Time, Temporal, and Californian patterns.
Control of Audible Silencing
It is possible to select an “auto-silence” mode, adjustable from 0 to 255 minutes. Each notification
appliance circuit programmed for alarm silence sequence, will be silenced upon time-out of the autosilence timer. The alarm silenced LED will flash, indicating the auto-silence time-out.
Audible Silence Inhibit
In addition to designation of waterflow zones, the entire control unit may be programmed to inhibit audible
silence for 0, 1, 3, or 6 minutes from the last alarm. System reset may also be inhibited.
The control unit includes a non-volatile memory recording up to 500 system events. Identified alarm,
trouble, supervisory trouble, and other significant events will be recorded along with the date and time of
occurrence, and can be inspected by operating front panel push buttons.
Events recorded in the history are:
• Alarm, Trouble, or Supervisory conditions.
• Drill, Tornado, Recall and General Evacuation.
• Activation of NACs or modules used for sounders or strobes.
• Unit used for command functions. (Silence, acknowledge, reset, etc.)
• PAS_INHIBIT switch activation.
• Alarm silence (manual and automatic).
• System reset.
• Power up.
• Entry to Programmer Mode.
• Secondary configuration edited.
• Validity check on backup configuration. (Errors detected or no errors detected)
• Running of comparison function. (Same or different)
All hardware is suitable for use in an interior or protected location.
Power Limiting
The AC power and battery wiring are not power limited. All other circuits leaving the control unit are
power limited, provided the proper installation rules are maintained.
Ground Fault Detection
The control unit provides ground fault detection and a ground fault will trigger the common fault buzzer
and system trouble LED.
Transient Protection
Transient protection devices are provided where needed to meet the requirements of UL864.
Security Functions
Processor control and addressing allow inclusion of several functions to assure security of the system.
Multi-lev el password protection of programming functions prevents unauthorized configuration changes.
Device type supervision: If the type reported by an addressable sensor or module, does not agree with
the configuration, the system reports a trouble.
Device address supervision: The system checks that all configured devices on the addressable device
circuit and the RS485 circuit responds to an address poll. If a configured device is missing, the system
reports a trouble. The system also polls unused addresses periodically. If a device responds to such a
poll of a non-configured device, the system reports a trouble. Two devices addressed the same also
cause a trouble to be reported.
REGULATORY STANDARDS
The FS-100 control unit meets the requirements of industry and government regulatory agencies as
noted.
Federal Communications Commission
The FS-DACT meets the requirements of the Code of Federal Regulations (CFR 47), Part 68, for

for fire service
In normal standby operation, the green AC POWER ON LED should be illuminated and no other indicator
operating. The display will show the system name, “System Normal” announcement and the current date,
day, and time.
B. Alarm Condition
1) GENERAL ALARMS
a) In case of alarm, the system alarm LED will operate in a flashing mode and the buzzer will sound.
Local audible and visual signals and remote alarm signals will operate, and the LCD panel display will
indicate the zone or point initiating the alarm.
b) On receipt of an alarm, proceed in accordance with the established emergency plan. Assure that all
personnel are accounted for, and notify the Fire Department.
c) To silence the audible after evacuation, where permitted by the codes and control unit programming,
press ALARM SILENCE. The alarm audible will be silenced, the alarm silence LED will be
illuminated and a system trouble indicated. Operating the ACKNOWLEDGE button will silence the
local buzzer and change the LED alarm indicator from flashing to steady.
2) Waterflow Alarms
Alarms detected on zones designated “waterflow” indicate sprinkler operation and the audible alarms
cannot be silenced in this condition. Operation of alarm silence will produce no effect.
3) Positive Alarm Sequence (PAS)
a) Activation of a point programmed for PAS, including two-stage manual stations, activates the Alarm
LED, display and buzzer (pulsing), but delays all other outputs (system and user) for 15 seconds.
b) Operation of the ACKNOWLEDGE button within 15 seconds will add 165 seconds to the timer value,
to make the total delay 180 seconds.
c) If an ALARM SILENCE button is pressed or the sensor returns to a normal reading before the
extended PAS delay time, the alarm sequence is aborted.
d) An alarm condition on a sensor programmed for direct alarm response (such as the key switch on a
manual station) will over-ride the PAS timer and activate the outputs.
4) Pre- Signal
a) A point activated by a PRE -SIGNAL alarm activates the alarm relay, alarm DACT, city tie, alarm
LEDs and buzzers, and all user programmed outputs normally, but does not activate any NACs.
b) Operation of the ALARM SILENCE button less than 180 seconds after initiation of the alarm prevents
operation of the NACs.
c) Failure to act within 180 seconds will result in activation of the NACs.
d) Receipt of another pre-signal or standard alarm during the delay period immediately sounds the
NACs.
e) A SYSTEM RESET is required to return the zone and input point to normal, whether or not the NACs
were activated.
NOTE: Do not reset the system until the alarm condition has been cleared. The LCD display on the will
indicate the area in which the alarm was detected. The detector initiating the alarm will display a light. If
more than one zone is in alarm, the last zone to be alarmed will be indicated on the display.
f) When the alarm condition has been corrected, return the system to standby operation by pressing the
SYSTEM RESET button.
C. Trouble Condition
a) In case of a trouble condition, the system trouble LED and any programmed trouble LEDs will be
flashing, the LCD display will identify the problem, and the buzzer will sound. Refer to the applicable
section of the system manual to determine the probable cause of the trouble and the action to be
taken.
b) When a trouble has been noted, the buzzer may be silenced by pressing the ACKNOWLEDGE
button. The trouble LEDs will change to a continuous display. If the trouble has not been corrected
when the trouble re-ring timer expires, the trouble display will revert to its original condition and the
buzzer resound.
c) If the control unit is programmed for trouble acknowledge required, when the indicated trouble
condition has been cleared, the system will revert to standby condition after the ACKNOWLEDGE
button is pressed.
Note: Some trouble conditions require a system reset to restore the control unit.
D. Supervisory Condition
Supervisory conditions are indicated similar to regular system trouble conditions except that when a
supervisory condition is cleared, the cleared condition continues to be indicated until it is acknowledged.
E. Maintenance
In order to insure continued safe and reliable operation of the fire alarm system, periodic inspection and
testing should be performed in accordance with applicable NFPA 72 standards.

from either control unit or auxiliary power (no combined source can be configured).
Remote Device Data
When connecting devices on the RS485 communications circuit, the data wires must be daisy chained
and with no T-taps to preserve the integrity of the data. Each end (two places) must be terminated with a
120 ohm termination resistor. The following diagrams show typical examples using the proper wiring.
The basic configuration of the FS-100 control unit includes one addressable device circuit. The devices
are polled by the control unit every few seconds and input or output functions communicated to determine
device status or function. The control unit monitors all device addresses for alarm and trouble conditions.

Addressable Device Wiring Diagrams
Proper connections for UL Listed compatible addressable devices are indicated below. Refer also to the
instruction sheets packed with each device.
Detectors and modules may be wired together according to several NFPA defined wiring styles. The
wiring style that is appropriate for your installation should be determined from the relevant building codes
and the Authority Having Jurisdiction.
Style 4 wiring permits branching of circ uit connections. The control equipment supervises modules
because they are active and must respond periodically to the control unit’s interrogation.

Note:
Addressable Devices:
Detectors, Monitor Modules, or Control Modules up to a maximum of 60 devices per addressable
device circuit. Maximum of 20 devices per Isolator Module. Maximum of 12 Isolator Modules per
addressable device circuit.
Detectors, Monitor Modules, or Control Modules up to a maximum of 60 devices per addressable
dev ice circuit. Maximum of 20 devices between Isolator Modules. Maximum of 12 Isolator
Modules per addressable device circuit.
Each detector uses an address between 01 and 60 on the addressable device circuit. All device
addresses are programmed into the device using the FS-DPI Device Programmer Unit. When installed,
the device is regularly scanned by the control unit and checked for its current sensor status. The control
unit will interpret and respond to the analog data as programmed. Each time the device is scanned the
integral green visible LEDs will flash. In the event of an alarm condition the red LEDs will flash at a faster
rate.
FS- DPT Photoelectric Detector with Thermal
The FS-DPT Photo/Thermal Detector allows programmable analog sensitivity with fixed thermal
temperature of 135° F. It requires a DB -11, DB-X11RS, ADBX-11, AD-11P, or ADX-11PR base.
FS- DT Thermal Detector
The FS-DT Thermal Detector is a fixed 135° F detector. It requires a DB-11, DB-X11RS, ADBX-11, AD11P, or ADX-11PR base.
FS- DP Photoelectric Detector
The FS-DP Photoelectric Detector allows programmable analog sensitivity. It requires a DB-11, DBX11RS, ADBX-11, AD-11P, or ADX-11PR base.
DB- 11, ADBX-11 and DBX- 11RS Detector Bases
The DB-11 base is a standard base designed for use with all FS-Series addressable and all 11-Series
conventional detectors. The DB-11 provides connection to an optional remote LED lamp (RLI-1 or RLI-2
lamp).
The ADBX-11 audible detector base is designed for use with all FS-Series addressable detectors. The
ADBX-11 provides means to obtain a local audible alarm at the specific detector location. The integral
horn on the ADBX-11 will sound when either the detector installed in the base has latched into the alarm
state, or when criteria developed through logic programming is met. It will remain on until the detector is
successfully reset, or the logic criteria are no longer met. A separate 24VDC power source is required to
operate the integral horn.
The DBX-11RS relay detector base is designed for use with all FS-Series addressable detectors. The
DBX-11RS provides a local Form C relay at the specific detector location. The relay on the DBX-11RS
will energize when either the detector installed in the base has latched in the alarm state, or when criteria
developed through logic programming is met. It will remain energized until the detector is successfully
reset, or the logic criteria are no longer met. The contact is rated at 3A, 120VAC, or 3A, 30VDC resistive.
AD- 11P and ADX-11PR Air Duct Housing
The AD-11P Air Duct Housing and the ADX-11PR Air Duct Housing are used with the FS-DP addressable
photo detector. Both housings provide a means to mount the FS-DP in an air duct for proper operation of
the detector in an air stream. The ADX-11PR also has an integral Form C contact that operates similarly
to the DBX-11RS relay base.
LIM- 1 Line Isolator Module
The LIM -1 Line Isolator Module is designed for use with FS-Series addressable detectors and provides
short circuit isolation on the indicating device circuit. Each LIM-1 can support up to 20 devices. The
system is limited to 12 LIM -1s on the circuit.
Each addressable module uses an address between 01 and 60 on the addressable device circuit. All
module addresses are programmed into the module using the FS-FPI Programmer / Tester. When
installed, the module is regularly scanned by the control unit and checked for its current circuit status.
The control unit will interpret and respond to the analog data as programmed. Each time the module is
scanned the integral green visible LEDs will flash. In the event of an alarm condition the red LEDs will
flash at a faster rate.
Transmit & Receive Interface Modules
The FS-TRI-S monitor module provides a single Style "B" (2-wire) initiating circuit for normally open dry
contact fire alarm and supervisory (tamper) devices. The FS-TRI-S is designed to mount directly inside a
4" square junction box, and has screw terminals for all field connections. The FS-TRI-S may be used to
monitor manual stations, waterflow switches, tamper (supervisory) switches or other dry, normally open
contact initiation devices. It uses a single module address between 01 and 60.
The FS-TRI-M monitor module functions exactly as the FS-TRI-S, except that it is smaller than the FSTRI-S, and it uses flying leads for field connections. The FS-TRI-M’s small size and light weight design
allows it to be installed inside a single gang box, or behind a device being monitored without being rigidly
mounted.
The FS-TRI-D monitor module is similar to the FS-TRI-S, except that it provides two Style ‘B” initiating
circuits for normally opened dry contact fire alarm and supervisory (tamper) devices. The FS-TRI-D uses
two consecutive module addresses between 01 and 60 on the addressable device circuit.
The FS-TRI-R monitor module is similar to the FS-TRI-S, except that it also provides a programmable
remote relay which operates a Form C contact within the module. Both the initiating circ uit and the relay
output share the same address.
FS- CZM Conventional Zone Module
The FS-CZM addressable conventional zone module allows the addressable device circuit to interface
and monitor two-wire conventional smoke detectors or normally open contact initiation devices. All twowire detectors being monitored must be UL compatible with the module. The FS-CZM communicates the
status of a single zone of conventional detectors to the control panel via the addressable device circuit.
When the panel scans the module, it transmits the status of one zone of two-wire detectors to the control
unit. Status conditions are reported as normal, open, or alarm. The FS-CZM uses a single module
address between 01 and 60 on the addressable device circuit.
Customized programming of the FS-100 control unit may be accomplished through a keypad included in
the control unit. A sixteen-key, telephone-style keypad mounts on the front panel within the cabinet. The
keypad may also be easily removed if desired. See the Siemens Programmer’s Manual (P/N 315-
699490) for detailed information of system programming.
PROGRAMMING SECURITY
The following levels of security protect the system from unauthorized use:
• User – Locked Door
• Maintenance – Locked Door and 4-digit Maint Password
• Technician – Locked Door and 5-digit Tech Password
The User and Maintenance Levels are also accessible from the Remote LCD Annunciator.
• Device sensitivity may be read out and alarm thresholds controlled on a per-point basis, as well as
setting overall percent obscuration and day/night variations. Individual points may also be disabled
for service.
To perform these functions on the unit, enter the 4-digit maintenance password into the control unit or
LCD annunciator. When the menu is displayed, select the desired function or sub-function and press the
appropriate operating button. When the function is complete, the menu will provide a command for
exiting the maintenance mode.
Note that any abnormal condition, such as disabled points, will report a
trouble. Confirmation of disabling or re-enabling a point is required to
complete the action, but acknowledgment of the trouble is not required, since
it resulted from operator action.
Activation of an alarm condition or a timeout after no button activity terminates Maintenance mode.
• The system may automatically scan the operating points and report to a printer, facilitating NFPA 72
test requirements. The control unit may perform this scan once a day, with the time selectable by the
user.
To initiate a non-programmed automatic test cycle, enter the 4-digit maintenance password into the
control unit or LCD annunciator. When the menu is displayed, select Auto-test and press the associated
switch. The Auto-test cycle will be completed and the control unit returns to normal. Results will be
displayed on the display (anomalies only) or the printer (full data) according to the selected mode.
• The system will automatically monitor drift of quiescent sensor output levels and report a
maintenance alert if a preset level is passed, or if a sensor drifts too quickly. This maintenance alert
is annunciated as a trouble.
• The system may be programmed to report the number of times the alarm verify function is initiated by
device, time of day, and/or day of week, allowing location of environmental problems. This datum is
available on the display as described in paragraph 1 above.
• The system may be programmed to alert the operator when scheduled maintenance is required.
• A 500 event history is maintained, with all events available for chronological review at the operator
level. This history may be cleared only with the Maintenance Level Code. For details on included
data and use of the history, see operation instructions.
To clear history when data has been read out and restoration of memory space is desired. Activate
maintenance mode as described above and follow menu instructions for clearing the event history.
CAUTION: If the control unit has remote connections to the Fire Department or
other monitor, be sure to disable the remote signals and notify the remote
monitoring station before performing test operations, since an off-normal
condition will be indicated.
Quick test is possible in one of two modes, (silent or audible) and is selectable on a per-zone basis. Any
number of zones may be placed into test at the same time, but only one mode of quick test operation is
possible for the whole system at one time. Points not in quick test operate normally. Quick test operation
initiates a system trouble condition.
In the silent mode, all alarm outputs are disabled and only the front panel indications and remote
annunciator LEDs operate. In the audible mode all system sounders will sound momentarily as each or
device is alarmed.
The system maintains a counter of the number of activation’s during the quick test and reports this value
when quick test mode is exited.
Quick test terminates into alarm if more than one device activates simultaneously, or if a device does not
return to normal after being activated within a configurable length of time.
Quick test terminates automatically into normal standby mode using a timer. The value of the timer is
configurable. The timer can be configured to limit the total time of the quick test (i.e. the timer is started
only when quick test is entered), or to limit the time between device activation’s (i.e. the timer is re-started
after each activation).
Alarm activation’s that occur in a system or zone in quick test or by a point in quick test cause the event
to be logged and printed. No other action is taken.
To initiate quick test, enter maintenance mode as described above and follow menu instructions to
configure and initiate the test.
Initiation of General Evacuation from the control unit, an RS485 LCD Annunciator, or an RS485 Remote
Processor causes termination of quick test and starts the normal alarm sequence.
Quick test may be terminated by a menu selection or by timeout (set at 5 to 30 minutes) from the last test
activation. Timeout system reactivation is annunciated by a 1/2 second on, 1/2 second off pattern from
system sounders programmed for drill use. A device in alarm condition when quick test is exited causes
the normal alarm sequence.
