Installation Procedures
Proper installation involves secure mounting, careful wiring to the FACP, and adherence to specified power supply requirements for optimal performance and reliability.
Mounting the ANN-80 Unit
The Fire-Lite ANN-80 is designed for flexible mounting options to suit various installation environments. Prior to mounting, ensure the selected location provides easy access for visual inspection of the LCD display and the disable switch. The unit can be surface mounted directly to a wall using appropriate screws and anchors, ensuring a secure and stable attachment.
Alternatively, it can be semi-recessed into a wall for a cleaner aesthetic. When semi-recessing, verify sufficient depth is available to accommodate the unit’s rear connections and wiring. Maintain a minimum clearance around the unit for adequate ventilation, preventing potential overheating. Avoid mounting near sources of extreme temperature, humidity, or physical damage.
Carefully consider the viewing angle and ambient lighting conditions to optimize display readability. Proper mounting contributes significantly to the overall functionality and longevity of the ANN-80 annunciator.
Wiring and Connections
Wiring the Fire-Lite ANN-80 requires careful attention to detail to ensure reliable communication with the Fire Alarm Control Panel (FACP). Utilize appropriately sized wiring, adhering to all local and national electrical codes. Typically, the ANN-80 connects to the FACP via a dedicated 4-wire communication bus – typically consisting of data positive, data negative, power, and ground.
Ensure proper polarity when connecting the power and ground wires. Incorrect polarity can damage the unit. The communication wiring should be run in a separate conduit from power wiring to minimize interference. Terminate all connections securely using approved connectors.
Refer to the FACP’s documentation for specific wiring diagrams and address settings. Double-check all connections before applying power to verify accuracy and prevent potential system malfunctions. Proper wiring is crucial for seamless integration and accurate system status reporting.
Power Supply Requirements
The Fire-Lite ANN-80 operates on a 24VDC power supply, typically sourced directly from the compatible Fire Alarm Control Panel (FACP). It’s crucial to verify the FACP’s power supply capacity is sufficient to support the additional load imposed by the ANN-80 annunciator. Insufficient power can lead to unreliable operation or complete failure of the display.
A dedicated power supply is recommended for optimal performance, minimizing the risk of voltage drops or interference from other devices. Ensure the power supply provides stable and regulated voltage within the specified range. Polarity must be strictly observed during connection – reverse polarity will likely damage the unit.
Consider utilizing a backup power source, such as a battery, to maintain operation during power outages. Always consult the FACP documentation for specific power supply recommendations and wiring instructions.

Operation and Functionality
The ANN-80 mimics the FACP display, showing system point status in English text; it features a disable switch and trouble LED for clear indication.
Understanding the LCD Display
The Fire-Lite ANN-80 utilizes a compact, backlit LCD display to provide a clear and concise representation of the fire alarm system’s status. This display mirrors the information presented on the main Fire Alarm Control Panel (FACP), offering remote visibility of critical events. The LCD screen is designed for easy readability, even in low-light conditions, ensuring personnel can quickly assess the situation.
Displayed information includes system point status – indicating which zones or devices are in alarm, trouble, or normal operation. The display’s format is designed to be intuitive, allowing for rapid interpretation of the system’s condition. The annunciator displays English-language text, simplifying understanding for all users. Proper understanding of the LCD display is crucial for effective response to fire alarm events, enabling swift and informed decision-making during emergencies.
System Point Status Display
The ANN-80’s LCD display meticulously presents the status of each system point – zones, devices, and initiating circuits – connected to the compatible Fire Alarm Control Panel (FACP). When a point activates, the display clearly indicates the location and nature of the event, such as “Zone 1 – Alarm” or “Smoke Detector – Trouble.” This detailed information allows personnel to pinpoint the source of the alarm quickly and efficiently.
The display mimics the FACP’s presentation, ensuring consistency and minimizing confusion. Normal, alarm, and trouble states are distinctly indicated, often using different colors or icons for immediate recognition. Understanding this point status display is paramount for effective fire safety management, enabling a targeted and informed response to any alarm condition. Accurate interpretation facilitates swift evacuation and fire suppression efforts.
Disable Switch and Trouble LED
The ANN-80 incorporates a disable switch, a crucial feature for silencing the annunciator during maintenance or testing procedures. When activated, this switch temporarily prevents audible alerts from the remote annunciator, without affecting the central FACP or other notification appliances. A dedicated disable trouble LED illuminates when the disable switch is engaged, providing a clear visual indication that the annunciator is temporarily silenced.
This trouble LED also signals other system faults or communication issues. A steady illumination indicates a general system trouble, while a flashing LED may signify a specific problem, such as a loss of communication with the FACP. Promptly addressing trouble conditions is vital for maintaining system integrity and ensuring reliable fire detection. Refer to the troubleshooting section for detailed guidance on interpreting and resolving trouble indications.

Troubleshooting Common Issues
This section provides solutions for typical ANN-80 problems, including display failures, communication errors with the FACP, and persistent trouble LED illumination for quick resolution.
ANN-80 Display Not Powering On
If the ANN-80 display fails to illuminate, begin by verifying the power supply connection at the unit itself. Ensure the wiring is secure and corresponds to the specified power requirements outlined in the installation section of this manual. Confirm that the Fire Alarm Control Panel (FACP) is actively supplying power to the remote annunciator circuit.
Next, inspect the fuse associated with the ANN-80’s power circuit – a blown fuse is a common cause of power loss. If the fuse is intact, use a multimeter to check the voltage at the ANN-80’s power terminals, confirming it matches the required voltage. A lack of voltage indicates a problem with the FACP or wiring. Finally, examine the disable switch; ensure it is not inadvertently activated, as this will cut power to the display. If issues persist, consult a qualified technician.
Communication Errors with FACP
Communication failures between the ANN-80 and the Fire Alarm Control Panel (FACP) typically manifest as a lack of updated system status or error messages on the annunciator display. First, meticulously check the wiring connecting the ANN-80 to the FACP’s communication bus, ensuring all connections are secure and free from corrosion. Verify the correct addressing scheme is configured for the ANN-80, as detailed in the network considerations section.
Confirm that the FACP is actively communicating on the network and that no other devices are causing interference. A multimeter can be used to test the communication lines for continuity. If the problem persists, attempt a system reset of both the ANN-80 and the FACP. Consult the FACP’s manual for specific reset procedures. If errors continue, professional assistance is recommended.
Trouble LED Illumination – Causes and Solutions
A lit Trouble LED on the ANN-80 indicates a system abnormality requiring attention. Common causes include communication faults with the FACP, a disabled annunciator state (due to the disable switch), or internal ANN-80 malfunctions. Initially, verify the annunciator isn’t intentionally disabled via the front-panel switch. If not, investigate communication issues as outlined in the previous section, checking wiring and addressing.
If communication appears normal, a persistent Trouble LED suggests an internal fault within the ANN-80 itself. Power cycle the unit; if the LED remains illuminated, contact qualified fire alarm service personnel for diagnosis and repair. Do not attempt internal repairs yourself, as this could compromise system integrity. Refer to the technical specifications for warranty information.
