NOTIFIER NFS-640 Addressable Fire Alarm Control Panels

Operating Information

Normal Standby Operation.

Green PoWER indicator lit steadily.
Red FiRE ALARM indicator off.
Yellow TROUBLE indicators off.

Alarm Condition.

Red FIRE ALARM indicator lit.
Alarm signaling devices activated.
Option module (remote station or supplementary alarm relay) activated.
Alarm in formation visible on LCD display.

Alarm Reset. After locating and correcting the alarm condition, reset the control panel by pressing the SYsTEM RESET Switch.
Trouble Conditions. Activation of trouble signal under normal operation indicates a condition that requires immediate attention. Contact your local service repres entative. Silence the audible signal by pressing the ACKNOWLEDGE/SCROLL DISPLAY SWitch. “The trouble indicator will remain illuminated.

Switch Functions

Acknowledge/Scroll Dis play. 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 automatically sends a special command to silence piezo sounders on the LCD-80 and ACS Annunciators. If more than one event exists, it advances the display to the next item and displays it for 3 seconds, or until the AcKNOWLEDGE/SCROLL DISPLAY Switch is pressed again (Scroll Display function).

Signal Silence. SiGNAL SILENCE performs all the functions of ACKNOWLEDGE. In addition, if an alarm exists, it turns off all silenceable circuits and illuminates the SiGNALS SILENCED indicator. It also sends a SiG-NALS SILENCED message to the LCD display, printer, and history file. A subsequent alarm will then resound the system.

Notes:

This unit is programmed to inhibit signal silence for
This unit is programmed to automatically silence alarm signal after minutes.

Drill. The NFS-640 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, LCD-80, printer, and History file.

System Reset. Resets the control panel in standalone applications.
Resets panel when enabled in network applications
Lamp Test. Press and hold the switch to lamp-test the LEDs.

LED Indicators

Power. Green LED which illum inates when primary power is applied to the control panel.
Fire Alarm. Red LED that flashes when one or more alarms occur. Iluminates steadily after alarms are acknowledged, and turns off when SYSTEM RESET is pressed after alarm clears.
Pre-Alarm. Red LED that flashes when a pre-alam 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, Hazard Alert or Tamper condition occurs, such as a sprinkler valve tamper condition. The LED turns off when the Supervisory condition clears. The 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.

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.

Periodic Testing and Maintenance

To ensure proper and reliable operation, system inspection and testing should be scheduled monthly, or as required by NFPA 72H 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 personnel of the test so alarm-sounding devices are ignored during the test period.
After Testing: Notify all fire, central station, and/or building personnel when testing is complete.

Audio/Telephone System Information

applies to voice and teleph one systems only!

AMG-1 Audio Message Generator.
- Audio Level: This green LED is illuminated when the audio level is correct.
- All Call: This green LED toggles ON and OFF with each press of the All Call switch.
- onLine: This green LED normally illuminates to show that the control panel is communicating with the Audio Message Generator.
- Trouble: This yellow LED illuminates to indicate the presence of a trouble local to the audio equipment (AMG, FFT and amplifiers).
- All Call switch: The All Call switch, when pressed, is used to activate all speaker circuits. These speaker circuits will deactivate when the All Call switch is pressed again (toggle function), provided an alarm is not present.
  If an alarnm is present, the speaker circuits remain active until manually turned of or until the system is reset. In dual-channel applications, press cither All Call switch for the same result.
- Speaker Volume: The local speaker volume control adjusts the volume of the speaker located on the AMG. It will not affect the volume of the speakers installed throughout the facility. If necessary, turn the volume down to prevent feedback during paging operations.
- Microphone: The microphone is used for paging operations. To page,select the speaker circuit (s) that you wish to page to by using the control switches on the VCM, DCM, or ACS or by us ing the All Call switch on the AMG. Press the switch on the side of the microphone and speak into the microphone Talk loudly enough to cause the green Audio Level LED to
  illuminate If the Audio Level LED remains off for 30 seconds, a system trouble will result
- Speaker Circuit Select: To turm a speaker circuit on, press the control button for a specific speaker circuit on the VCM, DCM, or ACS. The LED for the circuit selected will illuminate. The control button toggles the state of this circuit
- Tone/Message Select: To select an audio output function (voice message or audio tone), press the control button. Note: An active audio function may have to be deactivated before selecting the next function
- Dual-Channel Select: To select a channel, press the control button for the desired channel The LED on that point will illuminate. The control button toggles the selection of the channel. Channels must be selected for each speaker zone in a dual-channel system.

FFT-7 and FFT-7S Fire Fighters Telephone

Page Mode (FFT-7 only): The green LED will illuminate when the Page switch is depressed.
On-Line: This green LED will illuminate to show that power is applied to the FFT-7/FFT-7S.
Phone Trouble: This yellow LED illuminates to indicate an internal circuit trouble.
Line Trouble: This yellow LED illuminates to indicate an external circuit trouble.
Page switch: The Page switch allows the firefighter to page firom the FFT To page, select the speaker circuits that will carry the page by using the control button or by using the All Call switch on the adjacent AMG-1. Press the Page switch and talk loud enough into the handset to cause the green audio level LED on the AMG-I to illuminate
Incoming Calls: The green LED on the VCM mapped to a telephone circuit will flash and the piezo will beep. DO NOT PRESS THE ACKNOWL- EDGE BUTTON IN THIS CASE! To answer the incoming call. pick up the master handset and press the control button. Wait until the caller is connected (audible click in the receiver). To disconnect the call, momentarily press the telephone circuit control button again
Remote Paging: Answer the incoming call as described above. Press the Page switch on the FFT-7 and select the required speaker circuits by using the control buttons or the All Call switch on the adjacent AMG-1. Any caller connected to the FFT-7 from a remote location can now page to the selected speaker circuits.
