Key Components

• LCD Display: An 80-character backlit screen that provides detailed system status messages, time, and date. (As illustrated in Figure 1, displaying "NOTIFIER REMOTE ANNUNCIATOR ALL SYSTEMS NORMAL 08:00 03/15/10")
• Indicator LEDs: A vertical column of light-emitting diodes that illuminate to visually indicate various system conditions such as ALARM, SUPERVISORY, SYSTEM TROUBLE, POINT DISABLE, SIGNAL SILENCE, and OTHER.
• Control Buttons: A set of push-buttons enabling user interaction with the system, including ACKNOWLEDGE, SIGNAL SILENCE, RESET, DRILL, and LAMP TEST.

Setup and Installation

The LCD2-80 annunciator is designed for secure mounting within specific Notifier back boxes. Proper installation is critical for reliable operation.

Mounting

1. Select an appropriate mounting location that is easily accessible, visible, and protected from environmental extremes.
2. Securely mount the compatible back box (ABS-1T, ABF-1DB, or ABF-1B) to the wall or surface according to the back box's specific installation instructions.
3. Carefully align the LCD2-80 annunciator with the mounted back box and secure it using the provided hardware. Ensure a snug fit without overtightening.

Wiring

Connect the annunciator to the fire alarm control panel (FACP) using appropriate wiring methods as specified in the FACP's installation manual and local electrical codes. Ensure proper polarity and secure connections for all wiring terminals. Incorrect wiring can lead to system malfunctions or damage.

Operating Instructions

The LCD2-80 provides real-time status updates and allows for basic system control functions.

Display Information

The LCD screen continuously displays system status messages. For example, "ALL SYSTEMS NORMAL" indicates no active events. In the event of an alarm, trouble, or supervisory condition, the display will show detailed information about the event, including its type, location, and time.

Control Buttons

• ACKNOWLEDGE: Used to acknowledge new events. Pressing this button typically silences the local annunciator sounder and changes the event status from "new" to "acknowledged" on the display.
• SIGNAL SILENCE: Used to silence audible notification appliances (e.g., horns, bells) connected to the FACP. This action usually requires a specific access level to prevent unauthorized silencing.
• RESET: Used to reset the fire alarm control panel after an alarm or trouble condition has been cleared. This button typically requires a specific access level.
• DRILL: Initiates a system-wide fire drill. This function should only be used for testing purposes and typically requires a specific access level.
• LAMP TEST: Activates all indicator LEDs and illuminates the LCD backlight to confirm they are functioning correctly. This is a useful diagnostic tool.

Indicator LEDs

The LEDs provide a quick visual indication of the system's operational status:

• ALARM: Illuminates when a fire alarm condition is detected by the system.
• SUPERVISORY: Illuminates for supervisory conditions, such as a sprinkler system flow alarm or a valve tamper.
• SYSTEM TROUBLE: Illuminates for system faults, malfunctions, or abnormal conditions that require attention.
• POINT DISABLE: Illuminates when a specific detection point, zone, or output has been disabled within the system.
• SIGNAL SILENCE: Illuminates when audible notification appliances have been silenced.
• OTHER: Illuminates for other specific system conditions or events not covered by the primary indicators.

Maintenance

Regular maintenance ensures the reliable and continued operation of your Notifier LCD2-80 annunciator.

• Cleaning: Gently wipe the display screen and control buttons with a soft, dry, lint-free cloth. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the unit.
• Functionality Check: Periodically perform a LAMP TEST (using the dedicated button) to ensure all indicator LEDs and the LCD backlight are operational. Any non-illuminating LED or a blank display during this test may indicate a fault.
• System Testing: Follow the fire alarm control panel's (FACP) recommended testing schedule to ensure the annunciator communicates correctly with the main panel and accurately reflects system status.
• Visual Inspection: Regularly inspect the annunciator for any signs of physical damage, loose connections, or environmental issues.

Troubleshooting

This section addresses common issues you might encounter with the LCD2-80 annunciator.

Display is Blank or Unresponsive

• Check all power connections to the annunciator and the main FACP. Ensure power is supplied and stable.
• Verify that the annunciator is properly connected to the communication loop or data bus of the FACP. Check for loose or damaged wiring.
• Ensure the FACP itself is powered on and operating correctly.
• If the issue persists after checking connections and power, contact qualified service personnel for further diagnosis.

Indicator LEDs Not Illuminating During Lamp Test

• If individual LEDs fail to illuminate, the annunciator unit may require servicing or replacement.
• If all LEDs fail to illuminate during a lamp test, re-check power and communication connections to the FACP.

Annunciator Not Responding to Button Presses

• Verify that the annunciator has power and the display is active.
• Ensure the FACP is not in a state that prevents annunciator control (e.g., programming mode, system fault).
• Confirm that the user has the appropriate access level for the desired function (e.g., Signal Silence, Reset).
• If the problem continues, contact qualified service personnel.
