Description

The Agni Veiga Series Intelligent Addressable Network Communication Card (FAP-3002) is engineered to enable seamless,secure, and long-distance communication between multiple fire alarm control panels and repeaters. Built on the RS485 differential communication standards, the card supports multi-node networking with excellent resistance to electrical noise, making it ideal for harsh industrial and commercial environments. 

This communication card allows up to 16 nodes on a singe bus and supports communication distances of up to 1200 meters, depending on speed and cable conditions. The RS485 topology is best suited for bus, ring, or daisy-chain layouts, helping avoid signal reflection issues associated with star wiring. 

Designed for easy integration, the Comms PCD plugs directly into the control panel’s main motherboard and includes a socket for reconnecting the display board ribbon cable. Network configuration is managed using onboard DIL switches, allowing panels to operate either in standalone mode or network / repeater mode. 

With low power consumption, programmable outputs, fault-tolerant wiring support, and compatibility with legacy radial circuits, the Agni Veiga Network Communications Card is a cost-effective and scalable solution for expanding intelligent fire alarm systems. 

Job to be Done

Primary Job

When I need to connect multiple fire alarm control panels across a large site, I want a reliable network communication card that enables long-distance, noise-resistant data sharing so all panels operate as one coordinated fire alarm system.

System Integrator

When designing intelligent fire alarm networks, I want a scalable communication module that supports multiple panels and repeaters over long distances so the system can grow without redesigning the infrastructure.

Functional Jobs

Provide stable, noise-resistant RS485 communication so multiple fire alarm panels function as one coordinated system

How it Works

How does the Agni Veiga Network Communications Card Work?

The Agni Veiga Series Intelligent Addressable Network Communication Card (FAP-3002) works by creating a reliable RS485 communication network between multiple fire alarm control panels and repeater panels. It allows all connected panels to exchange status information, events, and system data over a single, fault-tolerant communication bus. 

Application & Solution

  • Large Commercial Building
  • Industrial Plant 
  • Hospital or Campus Installation
  • Legacy System Expansion 

How does the Agni Veiga Network Communications Card Work?

1. Install the Card

The Network Communications Card is plugged into the control panel’s main circuit board, and the display ribbon cable is reconnected through the card.

2. Set Network Mode

A DIL switch on the panel is set to enable network or repeater mode so the panel recognizes the communication card.

3. Connect RS485 Wiring

Panels are linked using a two-core RS485 cable through Comms A and Comms B terminals.

4. Establish Panel Network

Multiple control and repeater panels are connected on the same communication bus or fault-tolerant loop.

5. Transmit System Data

Alarms, faults, and system status are exchanged between panels using noise-resistant RS485 communication.

6. Maintain Reliable Operation

The system continues operating with monitored, fault-tolerant wiring and reports any network issues automatically.

FAQ

What is the Agni Veiga Network Communications Card used for?

The Agni Veiga Network Communications Card (FAP-3002) is used to network multiple intelligent fire alarm control panels and repeaters, enabling reliable data communication over long distances using RS485 technology. 

The card supports communication between up to 16 nodes on a single RS485 bus. This includes combinations of control panels and repeater panels, and the network can be expanded further using transceivers. 

The Network Communication Card supports communication distances of up to 1200 meters, depending on data speed and cable conditions. Lower speeds are recommended for longer distances to ensure stability. 

Yes, the Network Communications Card supports fault-tolerant loop wiring as well as redial and legacy wiring, ensuring continuous operation even in challenging network conditions. 

Each panel’s operating mode is selected using a DIL switch on the main PCB.

  • OFF: Standalone mode
  • ON: Network / Repeater mode
     Once enabled, the panel automatically recognizes and operates the communications card.

Yes, the product complies with BS EN 54-2 and BS EN 54-4, making it suitable for certified fire alarm system installations.
