Section 1 Operating Information
Normal Standby Operation.
1. Green POWER indicator lit steadily.
2. Red FIRE ALARM indicator off.
3. Yellow TROUBLE indicators off.
Alarm Condition.
1. Red FIRE ALARM indicator lit.
2. Alarm signaling devices activated.
3. Option module (remote station or supplementary alarm relay) acti-
vated.
4. Alarm information visible on LCD display.
Alarm Reset. After locating and correcting the alarm condition,
reset the control panel by pressing the SYSTEM RESET switch. If both
Fire and MNS conditions are present on the panel, SYSTEM RESET
must be pressed twice.
Trouble Conditions. Activation of trouble signal under normal
operation indicates a condition that requires immediate attention.
Contact your local service representative. Silence the audible signal by
pressing the ACKNOWLEDGE/SCROLL DISPLAY switch. The trouble
indicator will remain illuminated.
Section 2 Switch Functions
Acknowledge/Scroll Display. This 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 is silenced, it sends an acknowledge
message to the printer and history file. Acknowledge also automati-
cally sends a special command to silence piezo sounders on the
FDU-80 and ACS Annunciators.
Signal Silence. SIGNAL SILENCE performs all the functions of
ACKNOWLEDGE. In addition, if an alarm exists, it turns off all silence-
able circuits and illuminates the SIGNALS SILENCED indicator. It also
sends a SIGNALS SILENCED message to the LCD display, printer, and
history file. A subsequent alarm will then resound the system.
Notes:
1. This unit is programmed to inhibit signal silence for ____seconds.
2. This unit is programmed to automatically silence alarm signal after
_____ minutes.
Drill. The NFS-320 and NFS-320SYS waits for the Drill switch to
be pressed for 2 seconds (to prevent accidental activations), then turns
on all silenceable circuits (all FCM-1 modules/bell circuits that are
programmed silenceable), and turns off the Signals Silenced LED. It
sends a Drill Activated message to the LCD display, FDU-80, printer,
and History file.
System Reset. Resets the control panel in standalone applica-
tions. Resets panel when enabled in network applications.
Lamp Test. Press and hold the switch to lamp-test the LEDs.
Section 3 LED Indicators
Controls Active. Green LED which illuminates when the panel
assumes control of local operation as primary display. Turns off auto-
matically when another panel assumes control of local operation.
Power. Green LED which illuminates when primary power is
applied to the control panel.
Pre-Discharge. Red LED lights when any of the releasing zones
have been activated, but have not yet discharged a releasing agent;
turns off when no releasing zones are in the pre-discharge state.
Discharge. Red LED lights when any of the releasing zones are
active and in the process of discharging a releasing agent; turns off
when no releasing zones are discharging a releasing agent.
Abort Active. Yellow LED lights when an abort switch has been
activated; turns off when an abort switch has been pressed and its
timer is still counting down. Activation of a Manual Release Switch
will override Predischarge Delay and override an active Abort Release
Switch, resulting in an immediate agent release.
Fire Alarm. Red LED that flashes when one or more alarms occur.
Illuminates steadily after alarms are acknowledged; turns off when
SYSTEM RESET is pressed after alarm clears.
Pre-Alarm. Red LED that flashes when a pre-alarm threshold is
reached. The LCD display indicates if it is an ALERT or ACTION
pre-alarm.
Security. Blue LED that illuminates for a security alarm. LED
turns off after the alarm clears and SYSTEM RESET is pressed.
Supervisory. Yellow LED that flashes when a Supervisory, Haz-
ard Alert, or Tamper condition occurs, such as a sprinkler valve tam-
per condition. The LED turns off when the Supervisory condition
clears. The MNS, Hazard Alert, or Tamper indication will latch until
reset.
System Trouble. Yellow LED that flashes when one or more
troubles occur. Goes on steadily when ACKNOWLEDGE is pressed, and
turns off when all trouble conditions are cleared. Will illuminate if the
microprocessor watchdog timer fails (CPU FAIL).
Signals Silenced. Yellow LED that illuminates after SIGNALS
SILENCED has been pressed. Turns off when DRILL or SYSTEM RESET
is pressed.
Point Disabled. Yellow LED that illuminates when one or more
points are disabled. The LCD will indicate which points have been
disabled. Turns off when points are re-enabled.
Section 4 Audible Tone Indicator
Alarm. A continuous sounding tone.
Trouble/Security. A slow, pulsating tone signal having an equal
on and off time.
Supervisory. A fast, pulsating tone signal having an equal on and
off time.
Section 5 Periodic Testing and Maintenance
To ensure proper and reliable operation, system inspection and testing
should be scheduled as required by the Authority Having Jurisdiction,
or as required by NFPA 72 or local fire codes. A qualified Service
Representative should perform testing.
Before Testing: Notify fire department and/or central alarm
receiving station if alarm condition is transmitted. Notify facility per-
sonnel of the test so alarm sounding devices are ignored during the test
period.
After Testing: Notify all fire, central station, and/or building per-
sonnel when testing is complete.
