The IFC-200 is an intelligent fire alarm control panel designed for comprehensive fire and security signaling applications. It features a membrane switch panel for user interaction, including various switch functions and LED indicators to convey system status.

Function Description:

The IFC-200 operates in several modes: Normal, Trouble, Alarm, and Supervisory. In Normal Operation, the LCD display shows "All Systems Normal" and a custom message. The system continuously polls SLC devices and indicating appliance circuits, checks for valid replies, alarms, and troubles, monitors power supply and batteries, sends supervisory queries, refreshes displays, scans the keyboard, performs detector auto tests, and tests memory.

In Trouble Operation, the piezo sounds, the System Trouble LED flashes, and the trouble relay activates. The LCD displays detailed trouble messages, including the event type, device type, custom descriptor, software zone, and type of trouble (e.g., "OPEN CIRCUIT"). The ACKNOWLEDGE/STEP key silences the piezo, changes flashing LEDs to steady, and sends an ACKNOWLEDGE message to the printer and history file. If multiple troubles exist, the display steps through them. If all troubles clear, the system returns to normal operation.

Alarm Operation is similar to trouble operation but with distinct differences: the piezo sounds steadily, the System Alarm LED flashes, the display banner reads "ALARM," and the third line shows the first zone's label. Alarms latch, prevent clearing, recalculate control-by-event statements, activate timers (Silence Inhibit, Auto Silence), and activate the general alarm relay and zone Z00.

Supervisory Operation involves a warbling piezo sound, flashing Supervisory LED, and an "ACTIVE" display banner. Silenced alarms are not resounded, timers are not started, and the alarm relay is not activated (supervisory relay is activated).

Non-Alarm Point Operation involves monitor modules that activate control-by-event but not the System Alarm LED or piezo. These tracking points have three type codes:

• NON-FIRE: Ignored during fire alarms, no messages sent to LCD, history, printer, or LCD-80. Used for energy management or other non-fire situations to control output devices.
• HAZARD ALERT: Sends messages to LCD, history, printer, and LCD-80 (status "ACTIVE"), and changes coding programs for bell circuits to remain steady. Used for monitoring critical processes or hazardous situations.
• FIRE CONTROL: Operates regardless of fire conditions, sending messages to LCD, history, printer, and LCD-80. Used for air handler shutdown and intended to override automatic fire functions.

Trouble Monitor Point Operation is similar to trouble operation but with an "ACTIVE" display banner, "TROUBLE MON" type code, latching modules, and control-by-event statements.

Indicating Appliance Circuit Operation features four bell circuits with control-by-event statements and trouble functions similar to M510CJ modules. Their addresses are B01-B04, default type code is "BELL CIRCUIT," and they can be used for March Time, California Code, Temporal, and Two-stage coded functions.

Control-By-Event Operation (CBE) is managed through 99 software zones. Each system point can list up to five zones. A General alarm zone (Z00) can be listed for output points but is not activated by non-alarm or supervisory points. An active input device activates all software zones in its list, turning on output devices if any listed software zones are active. Zones 90-99 are reserved for special functions like cross-zoning.

Releasing Functions are handled by Zones 91-94, allowing up to four simultaneous release operations. Each zone includes:

• Delay: Programmed time from alarm activation to output device activation. If cross-zoning is selected, the timer starts with two or more devices in alarm. Values range from 0 to 60 seconds.
• Abort: Type of abort algorithm (ULI, IRI, NYC, or AHJ). ULI and IRI comply with UL Standard 864. The abort timer does not operate when set to "NO DELAY."
• Cross: If set to "Y," the timer and release circuit activation occur only if two or more devices with the same zone number are activated.
• Soak: Automatically shuts off releasing solenoids after a programmed time (0 or 10-15 minutes). Used in NFPA 16 applications only.

Intelligent Detector Functions:

• Analog Display: Reads and displays analog information from 99 analog detectors as percent obscuration of light per foot (%/ft).
• Sensitivity Adjust: Alarm levels can be manually set to 1.0%, 1.4%, or 3.0% obscuration, with 1.0% being most sensitive.
• Day/Night Sensitivity Operation: Can automatically force smoke detectors to minimum sensitivity (3.0%) during the day.
• Drift Compensation: Provides accurate and stable smoke readings by counteracting long-term drift from dust. It uses three measurements (ionization or photoelectric) and can be selected per detector. It provides a long-term measurement of clear air and alarm test level measurement. A trouble condition is reported when the drift compensation limit is reached or if the detector remains at very high/low levels for an extended period.
• Maintenance Alert: A trouble condition is reported per NFPA standards when the limit of drift compensation is safely applied, or if the detector remains at very high or very low levels for an extended period.
• Automatic Test Operation: Performs an automatic test of each detector every two hours. Failure results in an "AUTO TEST FAIL" trouble.
• Type Code Supervision: Monitors hardware device type codes. A mismatch between type code and program causes an "INVALID TYPE" point trouble.
• LED Control Operation: A global program selection prevents detector LEDs from blinking during normal conditions, beneficial for sleeping areas. Up to 99 LEDs can turn on during alarm conditions.
• Alarm Verification and Counter Operation: Performs alarm verification on selected intelligent smoke detectors (1551J and 2551J). Verification time is a global setting (0-60 seconds). Each detector has a verification counter (up to 99) that displays how many times it entered verification without timing out to alarm.
• Prealarm Operation (AWACSTM): If a 2551J, SDX-551TH, or 1551J detector exceeds the programmed Alert level, an Alert prealarm occurs, activating the piezo, Zone 99, and the Prealarm LED. Alert prealarms automatically restore. An Action prealarm occurs if a detector exceeds the action level threshold, activating all alert level functions and potentially a special Action software zone. Action prealarms latch until reset.

Time Functions:

• Real Time Clock Operation: Includes a crystal time base clock with lithium battery backup, providing time-of-day, date, and day-of-week. Displays in U.S. or European format.
• Time Control Command Operation: Zones 95 and 96 are reserved for control-by-time functions, activating and de-activating at specific times on certain days. Used for ancillary applications like lighting control or setback thermostats.
• Day/Night Sensitivity Adjust Operation: When Zone 95 or 96 activates, detector sensitivity is set to its 3.0% maximum (least sensitive) level. It returns to the programmed setting when the zone deactivates.
• Holiday Operation: Zone 97 is reserved for setting up to nine holidays. When the current date matches a holiday, the zone activates, controlling special days and serving as the eighth day in Zones 95 and 96 programming.

Coder Operation: Zone 98 is reserved for Coding functions, used only by bell circuits B01-B04. Available codes include March Time (120 PPM), Temporal Code (NFPA 72), California Code (10 sec on/5 sec off), and Two-stage (20 PPM for 5 min, then steady).

Presignal/PAS Operation: Zone 90 is reserved for presignal functions, delaying control points for human verification. If included in an M510CJ or bell circuit control-by-event list, it inhibits other control-by-event statements. Detectors and monitor modules must call out Zone 90. Zone 90 activates when an alarm occurs (without a PAS inhibit monitor module). It deactivates if a second alarm occurs, the DRILL key is pressed, or if PAS is selected and ACKNOWLEDGE/STEP is not pressed within 15 seconds. A programmable 0-180 second timer starts with the first alarm.

Special System Timers:

• Silence Inhibit Timer (0-300 Seconds): Starts with the first alarm and restarts with each new alarm, preventing the ALARM SILENCE switch from functioning.
• Auto Silence Timer (0, 600-900 Seconds): If selected and times out, it performs the same function as pressing the ALARM SILENCE switch. Pressing DRILL restarts the timer. Zero indicates no timer.
• Alarm Verification Timer (0-60 Seconds): If a smoke detector is selected for verification, its alarm is ignored during this time. If another alarm occurs, the timer deactivates, and the alarm activates. If the timer times out and an alarm still exists, standard functions occur. If no alarm exists after timeout, the verification counter increments.

Waterflow Circuits Operation: If an alarm exists from a monitor module with a Waterflow type code, the ALARM SILENCE switch does not function.

Disable/Enable Operation: Disabled input points do not cause alarms or control-by-event activity. Disabled output points are held "Off." All disabled points are treated as if in trouble, but the status banner reads "DISABL."

Style 6 and 7 Operation: If the SLC is wired and programmed for Style 6 or 7, the IFC-200 detects single faults and drives both ends of the line, recovering from the fault. The panel latches and displays the trouble until SYSTEM RESET is pressed. Style 7 requires M500XJ isolator modules.

Usage Features:

• Switch Functions: ACKNOWLEDGE/STEP, ALARM SILENCE, DRILL, SYSTEM RESET.
• LED Indicators: AC Power, Fire Alarm, Prealarm Warning, Supervisory, Alarm Silence, System Trouble.
• LCD Display: Provides detailed messages for normal, trouble, alarm, and supervisory conditions, including custom messages and point addresses.
• Read Status: Allows viewing point status on the LCD without a password, even during alarms or troubles. It displays detector address points (01-99), module points (01-99), indicating appliance (bell) circuits (01-04), System parameters, and software Zones (01-99).

Maintenance Features:

• Drift Compensation: Helps maintain detector performance over time by adjusting for dust contamination.
• Maintenance Alert: Notifies when detectors require maintenance due to drift compensation limits or sustained high/low readings.
• Automatic Test Operation: Regular self-testing of detectors to ensure functionality.
• System Reset: Clears M510CJ modules, bell circuits, resets power to 4-wire detectors, and performs a lamp test.
• Verification Counter: Tracks how many times a detector entered verification without timing out to alarm, aiding in identifying problematic detectors.
