[object Object],Switch 1 (SW1) ON = Key-switch disabled, OFF = Key-switch enabled. Switch 1 set to the OFF position enables key-switch operation. The keyswitch may now be used to enable the FDU-80 membrane switches, allowing remote switch functions, or lockout the switches, preventing remote switch functions.

[object Object],Switch 2 Set OFF to disable the internal piezo from sounding in response to system status changes (alarm, troubles, supervisories).

[object Object],Switch 3 Set OFF to configure the FDU-80 for Receive Only operation. The Receive Only setting must be used for all annnciators except the last or only FDU Annunciator on the EIA-485 line.

[object Object],Switch 4-6 Set these switches to the OFF position to configure the FDU-80 for proper communication with the NFS-320 or NFS2-640.

[object Object],Acknowledge/Step When the Acknowledge/Step switch is pressed and released, the FDU-80 sends an Acknowledge command to the control panel. Pressing the Acknowledge switch silences the local piezo sounder, the sounders located in all other system annunciators and the sounder located on the Fire Alarm Control Panel's main circuit board. Only one press is necessary regardless of the number of new alarms, troubles or supervisory signals. An acknowledge message is also sent to the printer and the history files in the FACP. Multiple active events (alarms, troubles, supervisories) are scrolled on the display at a one second rate, but may be held for sequential display by pressing and holding the Acknowledge switch. When more than one event exists, the first press of the Acknowledge switch silences system piezo sounders. The second press of the switch stops the scrolling and holds the event on the display for one minute. Subsequent pressing of the switch 'steps' through each active event.

[object Object],Silence When the Silence switch is pressed and released, the FDU-80 sends an alarm silence command to the control panel. The Silence switch performs the same functions as the Acknowledge switch. In addition, if an alarm exists, it turns off all silenceable NACs and causes the FACP Alarm Silenced LED to turn on while the FDU-80 will display a 'silenced‘message. It also sends an 'Alarm Silenced‘ message to the printer and the history file within the FACP. A subsequent new alarm will resound the appropriate NACs (Notification Appliance Circuits) and local sounders.

[object Object],Drill: Hold 2 Sec. When the Drill switch is pressed and held for at least two seconds (time required to prevent accidental activations), the FDU-80 will transmit a drill command to the control panel. This command causes the FACP to turn on all NAC outputs and all silenceable circuits (all control modules/NACs that are programmed silenceable). In the event that the system was previously silenced, the drill command will also turn off the Alarm Silenced LED. The 'Manual Evacuate' message is shown on the FDU-80 display. The same message is sent to the FACP display, printer and history files. The Silence switch operates on silenceable NAC outputs only.

[object Object],Reset When the System Reset switch is pressed and released, the FDU-80 sends a Reset command to the control panel. This will turn off all control modules and Notification Appliance Circuits, temporarily turns off resettable power to 4-wire detectors, causes a 'System All Normal‘ message to be displayed on the FDU-80 and sends a 'System Reset‘ message to the FACP display, printer and FACP history files. It also turns on all system LEDs, piezo sounders and LCD display segments as long as the Reset switch is held (lamp test). Any alarm or trouble that exists after a Reset will resound the system.

[object Object],Key-switch The key-switch is used to enable and disable the operation of the function switches if switch 1 on DIP switch SW1 has been placed in the OFF position. To enable the Acknowledge, Silence, Drill and Reset function switches, insert key into keys-witch located at the top right corner of the FDU-80. Make certain the key is inserted completely before attempting to turn it. Turn the key clockwise until it stops. Leave the key inserted while pressing the function switches. When finished with the function switches, turn key-switch counterclockwise to disable function switches. Note that the key-switch should normally be in the disabled position (fully counterclockwise), with the key removed and access to the key restricted to authorized personnel only. Do not leave the key unattended in the FDU-80.

[object Object],Configuration Switches (SW1) The setting on this DIP switch configure the operation of the LCD-80 and are set differently for ACS and Terminal modes.

[object Object],Addresses Switches (SW3 and SW2) When a LCD-80 is configured in ACS mode the following applies. DIP Switch SW3 rotary decimal switch SW2 are used together to set from 01 to 32. The LCD-80 responds to the start address plus the next addresses in sequence as defined by the size selection. If set to a size that requires more than one address, the LCD-80 will respond to all such addresses, but will only report communications failure if the start address is not received for 10 seconds or more.

[object Object],Programming Key Connector (P6) When the PK-1 Programming Key is inserted, the LCD-80 enters Program mode. When the key is removed, the LCD-80 automatically returns to normal operations. Programmable messages (20 or 40-character messages) can be stored within the LCD-80 using a personal computer and the PK-LCD-80 Programming Kit. These custom field messages are applicable only in ACS-mode – device label stored within an NFS-320 or NFS2-640 transfer through to an LCD-80 operating in Terminal Mode.

[object Object],Key-switch Connector (P5) For connection to an optional AKS-1B keyswitch. When the two pins on this interface are shorted, all six keys on the membrane panel will be ignored by the LCD-80.

[object Object],Mode Switches (SW4 & SW5) To configure the LCD-80 either ACS or Terminal Mode, set both side switches SW4 and SW5 to appropriate setting.

[object Object],Communication Bus (P2) Communication of the EIA-485 communication bus is made on terminal P2.

[object Object],Operating Power (P1) 24 VDC operating is provided to the LCD-80 on terminal P1. The power source must be power-limited. The power source for the LCD-80 does not require supervision as loss of power registers as a communication loss at the control panel.

[object Object],Acknowledge Switch When the ACKNOWLEDGE switch is activated on the front panel, the LCD-80 sends an acknowledge command to the control panel over the EIA-485 interface, using the first switch position on the start annunciator address. The LCD-80 also silences its local sounder. An acknowledge message is printed on the local printer. Silence Switch When the SILENCE switch is activated on the front panel, the LCD-80 sends a Signal Silence command to the control panel over the EIA-485 interface, using the second switch position on the start annunciator address. A SILENCE message is printed on the local printer. Reset Switch When the RESET switch is activated on the front panel, the LCD-80 sends a System Reset command to the control panel over the EIA-485, using the third switch position on the start annunciator address. A RESET message is printed on the local printer. *The Acknowledge, Silence, and Reset switch functions require programming from the AM2020, AFP-1010, NFS-3030 & NFS2-3030.

[object Object],Time Select Switch This switch is used in conjunction with the TIME SET switch to set the time and date on the LCD-80. This switch is ignored if the system is in alarm. Under non-alarm conditions, the bottom display line will show the present time and date when this switch is pressed. Time Set Switch When used in conjunction with the TIME SELECT switch, this switch sets the time and date into the LCD-80. This switch is ignored if the system is in alarm. The Time Set switch can be used to adjust the contrast of the LCD-80's display. Display Step/Lamp Test Switch This switch may be used to step the display through multiple alarms or troubles. If both alarms and troubles exist in the LCD-80, DISPLAY STEP may be used to display the troubles (after first stepping through all alarms).

[object Object],Acknowledge/Step Switch When the ACK/STEP switch is pressed on the front panel, the LCD-80 sends an Acknowledge command to the control panel, emulating a CRT terminal. Additional key punches will step through acknowledged events. Silence Switch When the SILENCE switch is pressed on the front panel, the LCD-80 sends a Signal Silence command to the control panel, emulating the CRT terminal. System Reset Switch When the System Reset switch is pressed on the front panel, the LCD-80 sends a Reset command to the control panel, emulating the CRT terminal.

[object Object],Pending Display The LCD-80 will keep a count of alarms in the system (number of alarm messages, minus alarm clear messages, since the last ALL SYSTEMS NORMAL message). When this key is pressed the alarm count is displayed in place of the time/date for 10 seconds. Contrast Adjust Repeatedly press this switch until the display’s contrast is acceptable. Local Silence/Lamp Test Switch If the backlit LCD display has been turned off due to a trouble condition in the system, pressing this switch will illuminate the display for 60 seconds. This switch also silences the local piezo. While it is held down, all segments on the display will be turned on and the piezo will sound.
