The ACKNOWLEDGE/STEP key silences the piezo sounder and changes
all flashing conditions to steady. Only one press is necessary regardless of
the number of new alarms, troubles, or supervisory signals. If the piezo
was silenced, depressing the switch sends an ACKNOWLEDGE message
to the printer and history file.
ACKNOWLEDGE also automatically sends a special command to the
LCD-80 and ACS annunciators to silence their piezo.
If more than one event exists, ACKNOWLEDGE/STEP advances the
display to the next item and holds there for 20 seconds, or until the
ACKNOWLEDGE/STEP key is pressed again.
ALARM SILENCE performs all functions of ACKNOWLEDGE/STEP.
In addition, if an alarm exists, it turns off all silenceable circuits and
illuminates the ALARM SILENCE LED. It sends an “Alarm Silenced”
message to the printer and the history file.
A subsequent new alarm will resound the system.

The IFC-200 waits for the DRILL switch to be held for two seconds
(to prevent accidental activation), then turns on all silenceable circuits
(all M510CJ modules/indicating appliance (bell) circuits that are
programmed Silenceable) and turns off the ALARM SILENCE LED. It
sends a Manual Evacuate message to the LCD display (shown
below), LCD-80, printer, and history file.
MANUAL EVACUATE
02:49P WED 07/08/93
SYSTEM RESET turns off all M510CJ modules and indicating appliance
(bell) circuits, breaks resettable power to 4-wire detectors, and sends an
All Systems Normal message to the LCD display, LCD-80, printer,
and history file. It also turns on all LEDs, piezo, and LCD display
segments as long as the SYSTEM RESET key is held, performing a lamp
test. Any alarm or trouble that exists after System Reset is performed will
resound the system.
The six LED indicators on the front panel operate as follows:
The green AC Power LED illuminates when 120 VAC power is applied to
the system.
The red Fire Alarm LED flashes when one or more alarms occur. It
illuminates steadily when ACKNOWLEDGE/STEP is pressed and turns
off when there are no longer any alarms on the system and RESET is
pressed.
The Yellow Prealarm Warning LED flashes when a prealarm threshold is
released. The LCD display indicates whether it is an alert or action
prealarm.
The yellow Supervisory LED flashes when one or more supervisory
conditions occur, such as a sprinkler valve tamper condition. It
illuminates steadily when ACKNOWLEDGE/STEP is pressed and turns
off when there are no longer any supervisory conditions on the system and
SYSTEM RESET is pressed. This indicator is used for security functions
in a combination fire/security protective signaling application. Refer to the
Combination Fire/Security Applications section of the IFC-200
Applications Technical Bulletin in this manual for more information.

The yellow Alarm Silence LED illuminates after an alarm condition
occurs, and the ALARM SILENCE key is pressed or the auto silence timer
times out.. It turns off when DRILL or SYSTEM RESET are pressed.
The yellow System Trouble LED flashes when one or more troubles occur.
It illuminates steadily when ACKNOWLEDGE/STEP is pressed and turns
off when all trouble conditions are cleared. This LED also illuminates if
the microprocessor watchdog timer fails (CPU FAIL).
With no alarms or troubles in the system, the LCD display shows the All
Systems Normal message. A typical example appears below:

ALL SYSTEMS NORMAL
11:13A SAT 12/25/94
The IFC-200 performs the following functions at regular intervals when in
normal mode:
●Polls all SLC devices and the four indicating appliance (bell) circuits.
Checks for valid reply, alarms, troubles, etc.
●Checks for power supply troubles, and checks batteries every
10 seconds.
●Sends a supervisory query over the LCD-80 interface and verifies the
proper response.
●Refreshes the LCD and LCD-80 display and updates the time.
●Scans the keyboard for SYSTEM RESET or ENTER commands.
●Performs a detector auto test.
●Tests the memory.
With no alarms present, the detection of a trouble in the system causes the
piezo to sound, the System Trouble LED to flash, and the trouble relay to
activate. The following is a typical message that occurs on the LCD
display. The same message is sent to the LCD-80, printer, and history file.

The first line of the display lists the type of event (trouble) and the type of
device (pull station).
The second line is a 19 character custom descriptor for this device
location.
The third line is the first software zone to which it is assigned (Zone 5),
and the type of trouble that exists (open circuit).
The last line is the time (“A” is AM) and date, plus the point address. The
M37 SLC address means module number 37. If the device in trouble was
a detector at the same address, this field would show D37.
Pressing the ACKNOWLEDGE/STEP key performs a block acknowledge,
causing the piezo to silence and the System Trouble LED to light steadily
regardless of the number of troubles, alarms, and supervisory signals in the
system. When ACKNOWLEDGE/STEP is pressed, and at least one new
alarm or trouble exists in the system, the ACKNOWLEDGE message is
sent to the printer and history file.
If the trouble clears, either before or after ACKNOWLEDGE, a Clear
Trouble message is sent to the printer. For example:
CLR TB PULL STATION WEST HALLWAY FLR 5 Z05 OPEN
CIRCUIT 11:13A 12/25/94 M37
If all troubles clear and there are no supervisory or fire conditions in the
system, the system returns to normal operation status, and the All
Systems Normal message is sent to the LCD display, LCD-80,
history file, and printer. This trouble restore occurs even if the troubles
were never acknowledged (auto restore).
If ALARM SILENCE is pressed when only troubles exist, it will have the
same effect as pressing ACKNOWLEDGE/STEP. The ALARM
SILENCED LED does not illuminate unless there is also an alarm in the
system.
If multiple trouble conditions exist in the system, the LCD and LCD-80
display step through them automatically at a two second rate. If the
ACKNOWLEDGE/STEP key is pressed, the display stops on the present
item for one minute, or until the ACKNOWLEDGE/STEP key is pressed
again. As the ACKNOWLEDGE/STEP key is pressed, the IFC-200
displays events in the following order:
Alarms, in order of address
Supervisory conditions or Security alarms, in order of address
Troubles, in order of address

Operating Instructions—IFC-200 Operating Instructions 7
IFC-200 alarm operation is similar to trouble operation, but with the
following differences:
●The Piezo sounds steadily, not pulsed.
●The System Alarm LED flashes.
●The Display Status banner reads ALARM.
●The third line of the display is the label of the first zone.
●Alarms latch and are not allowed to clear.
●Alarms cause recalculation of all control-by-event statements.
●Timers (Silence Inhibit, Auto Silence) activate.
●Alarms activate the general alarm relay and zone Z00.

Note that, like alarms, supervisory signals latch and may have their own
control-by-event. They do not cause resound of alarms or reactivation of
silenced alarm control-by-event statements. Supervisory circuits may also
have open circuit trouble, which operates just like any other trouble. If the
event is a security point activation, the Security LED operates in the same
manner as a supervisory event, but the LCD display shows a “Security”
type code. Refer to the Combination Fire/Security Applications section of
the IFC-200 Applications Technical Bulletin in this manual for further
information on security alarms.
Non-alarm points are monitor modules that activate the control-by-event
but do not activate the System Alarm LED or the piezo. These are
tracking points, and have three type codes:
●NON-FIRE--is ignored if there is a fire alarm in the system. Non-fire
codes do not send any message to the LCD, history file, printer, or
LCD-80. They are generally used for energy management or other
non-fire situations because their control-by-event statement can be
used to control output devices.
●HAZARD ALERT--sends the message to the LCD, history file,
printer, and LCD-80 (status is “ACTIVE”), and changes any coding
program for the four indicating appliance (bell) circuits to remain on
steadily. These points may be used for monitoring critical processes
or other hazardous situations, such as tornadoes.
●FIRE CONTROL--operates regardless of any fire condition, sending
messages to the LCD, history file, printer, and LCD-80. These codes
are generally used for air handler shutdown, and are intended to
override automatic fire functions.
The Trouble Monitor-type modules monitor remote power supplies or
other external equipment. Operation is similar to trouble operation but
with the following differences:
●The Display Status banner reads ACTIVE.
●The Type code reads TROUBLE MON.
●The modules latch.
●The modules may have control-by-event statements.

Operating Instructions—IFC-200 Operating Instructions 9
Four-indicating appliance (bell) circuits have control-by-event statements
and trouble functions similar to M510CJ modules on the SLC loop.
Differences are:
●Addresses (last three digits in LCD field ) are B01, B02, B03 or B04.
●The default type code field is “BELL CIRCUIT.”
●Circuits may be used for the following coded functions (M510CJ
modules may not): March Time, California Code, Temporal, and
Two-stage.
Control-By-Events (CBE) in the IFC-200 are done through 99 software
zones. Each system point (detector, monitor module, control module, or
indicating appliance circuit) may list up to five zones in its program
information. A General alarm zone (Z00) may be listed for output
(control) points, but is not necessary to list for input points. Z00 is not
activated by non-alarm or supervisory points.
If any input device (detector or monitor module) becomes active, and it is
not disabled, it activates all software zones in its list. An output device
(M510CJ module or indicating appliance (bell) circuit) that is not disabled
is turned on if any of the software zones in its list are active. This is
basically an “or” functionality. Zones 90 through 99 are reserved for
special functions such as cross-zoning (see the IFC-200
Programming/Status Change Technical Bulletin in this manual).
Zones 91, 92, 93, and 94 are reserved for special releasing functions. This
allows for up to 4 simultaneous release operations. Each zone includes the
following:
Delay--is the programmed time from alarm activation of an initiating
device mapped to this zone, until activation of all output devices mapped
to this zone. If cross-zoning is selected, the delay timer starts when two or
more devices are in alarm. The timer XX values may be set from
0 seconds to 60 seconds. If Abort or Manual Release type M500MJ
modules are mapped to this zone they affect the timer operation as defined
below.
Abort--is the type of abort algorithm used by the zone. It may be one of
the following four types: ULI, IRI, NYC, or AHJ, defined as in Table 1.

Cross--may be set Y (yes) or N (no). If yes, the start of the timer and
subsequent activation of release circuits will only occur if two or more
devices having the same zone number in their CBE are activated.
Soak--is used to automatically shut off the releasing solenoids several
minutes after the zone turns them on. It may be programmed for zero
(no soak timer), or 10 to 15 minutes. Use in NFPA 16 applications only.
See the Special Zone Change section of the IFC-200 Programming/Status
Change Technical Bulletin for details on programming Cross and Soak.
Refer to the Releasing Applications section of the IFC-200 Applications
Technical Bulletin in this manual for detailed information about releasing
applications.
The IFC-200 reads and displays analog information from its 99 analog
detectors. The LCD displays percent obscuration of light per foot (%/ft).
Alarm levels for the intelligent detectors may be manually set to one of
three within the UL obscuration range, 1.0%, 1.4%, or 3.0%; 1.0% being
the most sensitive and 3.0% the least sensitive.

The system can be programmed to automatically force smoke detectors to
their minimum sensitivity (3.0%) during the day. For more information,
refer to the information on Time Control Command Operation later in this
chapter.
Intelligent detector drift compensation provides accurate and stable
readings of smoke, counteracting long term drift caused by dust
contamination and other long-term environmental factors. It permits a
detector to remain within performance specifications throughout its life
span, quickly detecting true fires while rejecting false signals. The drift
compensation algorithm uses three measurements (described below) from
each ionization or photoelectric detector. Drift compensation can be
selected on a per detector basis. Refer to the IFC-200 Programming/
Status Change Technical Bulletin in this manual for further information.
Drift compensation provides a long-term measurement of a location’s
clear air. This is an average reading that moves slowly. It adjusts to a
gradual buildup of dust contamination, unaffected by true smoke, even
from smoldering fires.
Drift compensation also provides alarm test level measurement. Special
electronics in the detector and panel software periodically command each
detector to stimulate an alarm level reading from the sensing chamber.
Under normal conditions, present chamber readings are close to the
stored air clear value. If smoke occurs, the chamber reading moves toward
the alarm test level.
IFC-200 software converts the present chamber reading to percent per foot
(%/ft) obscuration, based on its position between the known clear air and
test values. The accuracy of this measurement method meets NFPA 72E
requirements for calibrated smoke test instruments.
Upon reaching the limit of drift compensation that may be safely applied,
a trouble condition is reported, per NFPA standards. This trouble
condition also activates if the detector remains at very high or very low
levels for an extended period of time. Below is a typical LCD display
when a trouble condition is reported.

The IFC-200 performs an automatic test of each detector every two hours.
Failure to meet the test limits causes an AUTO TEST FAIL trouble
type. SYSTEM RESET clears this trouble.
The IFC-200 monitors hardware device type codes at intervals. If the type
code and program do not match, a point trouble occurs. The trouble label
is INVALID TYPE.
The IFC-200 includes a global program selection to prevent detector LEDs
from blinking during normal conditions. This feature is beneficial in
sleeping areas, where the flashing light may be objectionable. As a
standard function, the IFC-200 allows up to 99 LEDs to turn on during
alarm conditions.
The IFC-200 performs alarm verification on selected intelligent smoke
detectors (1551J and 2551J only). Selection of detectors for alarm
verification is described in the IFC-200 Programming/Status Change
Technical Bulletin in this manual. The verification time is a global
program selection of 0 to 60 seconds. Each detector includes a
verification counter, which displays the number of times that detector
entered verification but did not time-out to alarm. The counter counts
to 99 and holds. Only clearing the history or setting the detector into
alarm clears the counter. Refer to Clear Verification Counters in the
IFC-200 Programming/Status Change Technical Bulletin.
If an 2551J, SDX-551TH, or 1551J detector exceeds the programmed
Alert level, it causes an Alert prealarm situation. When this occurs, the
piezo is activated, Zone 99 is activated, and the Prealarm LED is
illuminated. The following typical message is sent to the LCD, LCD-80,
printer, and history file:
PREALM SMOKE (PHOTO)
ROOM 5024
0.50%, 1.00%, ALERT
11:13A 12/25/94 D66
In this example, the detector is programmed for alarm at 1.00% per foot,
and has now reached the alert level programmed for 50% of that, or 0.50%
per foot. The 0.50% is a realtime display and may change. Alert
prealarms automatically restore.

An Action prealarm is indicated if a detector exceeds the action level
threshold. When this occurs, all functions of the alert level occur, plus a
special Action software zone (5th zone) may be activated if programmed.
Prealarms latch until reset. A typical Action prealarm display appears

The IFC-200 includes a crystal time base clock that provides time-of-day,
date, and day-of-week. The clock IC includes its own lithium battery
backup. Time is normally displayed in U.S. format, with 12 hour time and
month/day/year, but may be programmed for European time format with
24 hour time and day/month/year.
Zones 95 and 96 are reserved for control-by-time functions. These special
zones may be programmed to activate at one time-of-day and de-activate
at another time, and may do so for only certain days of the week. Any
control point may be turned on and off (lighting control, set-back
thermostat, etc.), by using one of these zones. These functions are
intended for ancillary (non-fire) applications.
When either Zone 95 or Zone 96 activates, it sets detector sensitivity to its
3.0% maximum (least sensitive) level. When the zone deactivates, the
sensitivity returns to its programmed setting. For day/night sensitivity
purposes, Zones 95 and 96 may be thought of as day zones.
Zone 97 is reserved for setting holidays (up to nine days). When the
present date matches any one of these nine dates, the zone activates. This
function controls special days of the year and is also used as the eighth day
in the programming of Zones 95 and 96.

Zone 98 is reserved for Coding functions. These functions are only used
by the indicating appliance (bell) circuits B01-B04. If Zone 98 is called
out for M510CJ modules, it has no effect. Only one type of code may be
selected:
●March Time Pulses at 120 PPM
●Temporal Code Pulses temporal code (see NFPA 72)
●California Code Pulses 10 sec. on/5 sec. off
●Two-stage Pulses at 20 PPM for 5 min., then stays on steadily
Indicating appliance (bell) circuits pulse 20 PPM when activated by
Zone 98 under alarm conditions (if no other zone has activated the circuit).
After five minutes, Zone 98 stops pulsing and remains on steadily unless
ACKNOWLEDGE/STEP has been pressed. Pressing DRILL changes this
to steady.
Zone 90 is reserved for presignal functions. This zone is used to delay
control points for human verification. If this zone is included in an
M510CJ, or indicating appliance (bell) circuit control-by-event list, it
inhibits all other control-by-event statements. Detectors and monitor
modules must call out Zone 90 in their program to be included in the
Presignal/PAS operation.
●When any alarm occurs, and no PAS inhibit type monitor module
activates, Zone 90 activates.
●If a second alarm activates or the DRILL key is pressed, Zone 90
deactivates.
●If PAS is selected, and the ACKNOWLEDGE/STEP is not pressed
within 15 seconds, Zone 90 deactivates.
At the first alarm, a programmable 0 to 180 second timer starts.
●If Signal Silence occurs, the timer is frozen.
●If the timer expires, Zone 90 deactivates. The alarm relay and
transmitter are delayed if PAS is selected, but are not delayed for
presignal operations.
The Silence Inhibit Timer starts with the first alarm, and restarts with each
new alarm. It prevents the ALARM SILENCE switch from functioning.
If the Auto Silence Timer is selected, and times out, it performs the same
function as pressing the ALARM SILENCE switch. Pressing the DRILL
switch restarts the timer. A value of zero indicates that no timer is
activated.

●If a smoke detector is selected for verification, its alarm is ignored
during the verification time.
●If an alarm from another point occurs while timing, the timer
deactivates and the alarm activates.
●If the verification timer times out and an alarm still exist, the alarm
performs all standard functions.
●If the verification timer times out and an alarm no longer exist, the
verification counter increments for this device, and returns to normal.
If an alarm exists from a monitor module point that has a Waterflow type
code, the ALARM SILENCE switch does not function.
Disabled input points do not cause an alarm or any control-by-event

Read Status operation aborts and the LCD returns to the previous display.
Pressing the SYSTEM RESET key also aborts Read Status mode.
Read Point operations display point status on the LCD display, but not to
the printer or the history file. After a point is read, the down key may be
used to read the next point in the SLC address sequence, and the up key
used to read the prior point in sequence. The sequence of point display
follows this sequence: Detector address points 01-99, module points 01-99,
indicating appliance (bell) circuits 01-04, System parameters, and software
Zones 01-99. The procedure for selecting a point is described above in

The present reading of the percent per foot of obscuration of light (does
not exist for modules) is 0.15%.
Dindicates that drift compensation is enabled.
Pindicates that prealarm is enabled.
The alarm threshold selection in percent per foot obscuration (does not
exist for modules) is 3.00%.
V08 indicates that the detector is programmed for alarm verification. The
numeral 8 is a verification tally, and indicates that this device has entered
the verification cycle 8 times since the counter was last cleared.
Note: This field does not exist if this device is a module. If the device is
a control module or indicating appliance (bell) circuit, an “S” or
“W” may appear in this area, indicating that the module is
programmed for Signal Silence or Walk Test activation.
D13 is the point address. “D” indicates Detector and could be “M” for
module, “B” for indicating appliance (bell) circuit, or “Z” for software
Zone.
If the point is not installed, a Read Status command to that point results in
a NOT INSTALLED message on the display.
The following typical format is used to display software zones 01 through 89:
OFF SOFTWARE ZONE
FLR 5 MAIN BUILDING
Z20

Operating Instructions—IFC-200 Operating Instructions 19
Where:
OFF is the zone status (could be ON)
FLR 5 MAIN BUILDING is the custom programmed label for this zone.
Z20 is the zone number
Note: To read the status of a zone directly, press “*”, then “#”, then the
zone two digit number, then ENTER.
The following typical format is used to display software Zone 90
(Presignal Delay Control):
OFF SOFTWARE ZONE
PRESIGNAL DELAY
DELAY=180
PAS=YES Z90
Where:
DELAY=180 indicates the programmed presignal delay in seconds.
PAS=YES indicates that Positive Alarm Sequence operation has been
selected in the program. If PAS has not been selected, the line reads
PAS=NO.
Z90 is the selected zone number.
The following typical display is used for Zones 91, 92, 93, or 94
(Releasing Control Zones):
OFF SOFTWARE ZONE
RELEASE CONTROL
DELAY=30 ABORT=ULI
CROSS=Y SOAK=10 Z91
Where:
DELAY=30 indicates programmed delay time, in seconds.
ABORT=ULI indicates the abort function, if an abort switch is mapped to
this zone (ULI, IRI, NYC, or AHJ).
CROSS=Y indicates that cross zoning is used (two or more detectors must
be programmed to this zone to activate the zone in alarm).
SOAK indicates the soak timer (automatic shut off) value in minutes.
(00 = no soak timer).

20 Operating Instructions—IFC-200 Operating Instructions
The following typical format displays Zones 95 or 96 (time control zones).
In addition to automatic activation of non-fire control points, this zone
may be used for detector day/night sensitivity select. If you want
day/night sensitivity for a smoke detector, Zone 95 or 96 must activate it.
When day/night sensitivity is active, detector sensitivity goes to the low
setting (3.00%) during the day.
OFF SOFTWARE ZONE
TIME CONTROL
ON=7:00 OFF18:00
DAYS=MTWTF H Z95
Where:
ON=7:00 OFF=18:00 indicates the programmed times that this zone
automatically turns on and off each day. The times are in 24 hour
(military) format.
DAYS= MTWTF H indicates the programmed days-of-week that the on/off
times are effective. “H” is a holiday, defined by Zone 97.
Note: To program midnight, enter 00:00. 24:00 is invalid.
The following typical format displays software Zone 97 (Holiday Zone):
OFF HOLIDAY ZONE 97
01/01 04/10 05/26
07/04 09/07 11/26
11/27 12/24 12/25
The numbers are day/month program selections for holiday days of the
year.
The following typical format is used to display software Zone 98 (coders):
