2.3 Wiring and Connection

Refer to the specific installation manual for the NFS-3030 or NFS2-3030 panel for detailed wiring diagrams and connection procedures. The LCD-160 connects to the main fire alarm control panel via a dedicated communication bus. Ensure all connections are secure and correctly terminated to prevent communication errors.

2.4 Power-Up and Initial Test

Once all connections are made, apply power to the fire alarm control panel. The LCD-160 should power on and display its initial boot sequence. Verify proper communication with the main panel by observing the display for system status messages.

3. Operating Instructions

The LCD-160 serves as a remote annunciator, providing real-time information about the fire alarm system's status. It displays events such as alarms, troubles, and supervisory signals, and allows for certain control functions depending on system configuration.

3.1 Display Navigation

Use the navigation buttons (typically arrow keys) on the LCD-160 to scroll through event logs, view detailed information about specific points, and access various system menus. The display will show prompts and instructions for navigation.

3.2 Acknowledging Events

When an event occurs (e.g., an alarm), the LCD-160 will display the event and typically activate an audible tone. Press the 'Acknowledge' button to silence the local annunciator tone and acknowledge the event on the system. This does not clear the event but confirms it has been noted.

3.3 Resetting the System

After an alarm or trouble condition has been resolved, the system may need to be reset. Press the 'System Reset' button on the LCD-160 (if enabled and configured) to clear active alarms and restore the system to its normal operating state. Ensure all conditions are clear before attempting a reset.

4. Maintenance

Regular maintenance ensures the continued reliable operation of the LCD-160 and the overall fire alarm system. Perform the following tasks periodically:

• Cleaning: Gently wipe the display and exterior casing with a soft, dry, lint-free cloth. Do not use abrasive cleaners or solvents, as these can damage the display or finish.
• Visual Inspection: Periodically inspect the unit for any signs of physical damage, loose connections, or unusual conditions.
• Functional Test: As part of routine fire alarm system testing, verify that the LCD-160 accurately displays system status and that all buttons are responsive.

5. Troubleshooting

This section provides guidance for common issues. For complex problems, contact qualified service personnel.

• Display is Blank:
  • Check power supply to the main fire alarm control panel.
  • Verify communication wiring between the LCD-160 and the main panel.
  • Ensure the unit is securely connected to its power source.
• No Communication with Main Panel:
  • Inspect communication wiring for breaks, shorts, or incorrect termination.
  • Confirm the main fire alarm control panel is operational.
  • Check the address settings of the LCD-160 (if applicable) to ensure it matches the system configuration.
• Buttons Unresponsive:
  • Gently press buttons to ensure they are not stuck.
  • Power cycle the main fire alarm control panel (if safe to do so and following proper procedures).

If troubleshooting steps do not resolve the issue, contact a certified Notifier technician or your fire safety equipment supplier.
