Aritech 2X-LB 2 Loop Expansion Card

1. Product Name: Aritech 2X-LB 2 Loop Expansion Card

2. Description:

What Is the Aritech 2X-LB Loop Expansion Card?

The Aritech 2X-LB is a plug-in expansion card that adds two extra loops to Aritech 2X series addressable fire alarm control panels with 2 loop. By doubling the number of devices the panel can support, it enables single-panel systems to be expanded. Aritech panel accessories are also now offered by Carrier under the Kidde Commercial umbrella.

Operating Principle

The card plugs directly into the front of the panel’s main board and works with the main processor to manage two new addressable loop circuits. Detectors, call points and modules connected to these loops are polled by the panel in the same way as devices on the other loops. The card also includes 4 supervised sounder/fire routing output, which can also be used as a freely programmable output, and 128 additional programmable zone.

Role in Fire Detection Systems

When a project grows, the existing panel’s capacity can be increased with the 2X-LB instead of installing a second panel and a Firenet network. This keeps all loop cabling in one place and means that only one panel needs to be powered and maintained. System expansion becomes more flexible and cost-effective. Note that the card can only be used with 2-loop panels.

Why Choose It?

• Doubles capacity: 2 additional loops double the number of devices supported per panel.
• Additional outputs: 4 supervised, programmable output is supplied with the card.
• No additional cabling required: Plugs directly into the front of the main board.
• Centralised management: All loops are managed from a single panel without networking.
• Easy maintenance: Plug-in connectors speed up maintenance and replacement.

Installation and Commissioning

The panel must be de-energised and the battery disconnected before installation. 2The X-LB is fitted into slot number 2 on the panel’s easily removable chassis and secured with screws; no additional cabling is required between the card and the panel. For new loop circuits, 0,129-3,31 mm² unshielded twisted-pair cable is recommended, and the loop length must not exceed 2 km. Once the card is installed, the new loops are added via the panel menu, devices are enrolled using automatic configuration, and zones and outputs are programmed. Installation in accordance with EN54 and local regulations is recommended.

Compatible Products

The 2X-LB is compatible with 2-loop Aritech 2X-AF2-19 addressable fire alarm control panels; 1-loop 2X-AF1-19 panels do not support this expansion. Aritech 2000 series DP2061N, DT2063N and DP2061T detectors can be connected to the added loops using DB2002, DB2004 or DB2016 bases.

Frequently Asked Questions

Can the 2X-LB be installed in any panel? No. The card can only be used in 2-loop panels, expanding them to 4 loops.

Is additional cabling required for the card? No. The card plugs directly into the front of the main board; only the new loop circuits need to be connected.

What advantage does the 2X-LB offer over networking? All loops are brought together on a single panel, only one panel needs to be powered, and the system can be expanded without a Firenet network.
