Aritech 2010-2-NB Fire Panel Network Card

1. Product Name: Aritech 2010-2-NB Fire Panel Network Card

2. Description:

What Is the Aritech 2010-2-NB Network Card?

Aritech 2010-2-NB is a network printed circuit board used to connect Aritech 2X series fire alarm control panels and repeater panels on a shared Firenet network. It plugs directly into the panel's main board and provides redundant Class A communication over RS485.

Operating Principle

The card fitted in each panel or repeater makes the device a node on the network. The nodes are connected in a ring; with a Class A topology, communication can continue in the opposite direction if there is a break at any point in the line. The default network capacity is 32 nodes and 32 loop; PAK licences can increase this to 64 nodes and 256 loops, with a distance of up to 1200 m between nodes. Copper/fibre converters are recommended for longer distances or where there are EMC issues.

Role in Fire Detection Systems

The network card allows multiple panels to operate as a single system. This makes it possible for each floor in a building to be controlled by its own panel, for different buildings on a site to be connected in one system, or for the system load to be distributed across multiple panels. It is also required to extend the panel interface to different locations, such as entrance doors, using repeater panels.

Why Choose It?

• Redundant Class A network: Communication is maintained in the event of a single-point line fault, thanks to the ring topology.
• Long distance: Supports distances of up to 1200 m between nodes.
• Panel and repeater compatibility: For use with both fire panels and repeater panels.
• Easy installation: Plugs directly into the front of the main board; no additional cabling is required.
• Flexible expansion: New panels can be added to the existing system over the network.

Installation and Commissioning

Before installation, disconnect the panel from the mains and battery supply. Fit the card into slot number 4 on the chassis using the plastic spacer, then secure it with a screw; no additional cable is required between the card and the panel. To prevent electromagnetic interference, the mains cable must enter the cabinet from below. Wire the RS485 line between nodes in a ring and assign a network address to each node. If the distance between nodes exceeds 1200 m or there is an EMC risk, plan to use copper/fibre converters. After commissioning, check on the panel that all nodes are visible on the network.

Applications

• Existing 2X systems expanded over a network

Compatible Products

2010-2-NB is used as an optional accessory in Aritech 2X-AF1-19 and 2X-AF2-19 fire alarm control panels; it is fitted as standard in the 2X-AFR-19 repeater panel. If only local expansion for 1-2 loops is required, the 2X-LB loop expansion card is an alternative solution.

Frequently Asked Questions

What happens if a cable in the network breaks? As the network uses a Class A ring topology, communication continues via the other direction and the fault is reported by the panel.

What can be done if 1200 m is not enough between nodes? For longer distances or EMC issues, using a copper/fibre converter is recommended.

Do I need to purchase a separate card for the repeater panel? No. The 2X-AFR-19 repeater comes with this card already fitted; it must be added separately to the fire panels on the network.
