Description

The SK-NIC Network Interface Card is used when networking a group of Fire Alarm Control Panels (FACPs). It is used to link the panels together.

[NOTE] The SK-NIC provides a common communications link for the 6700, 6808, and 6820/6820EVS. These panels cannot be linked together for peer-to-peer networking.

Compatibility

The SK-NIC is compatible with the following Honeywell Silent Knight and Farenhyt Series FACPs. For information on programming and addressing, refer to the Networking / Common Communication link Section of the FACP Installation Manuals.

• IFP-2100/ECS
• IFP-300/ECS
• IFP-75
• 6820/6820EVS
• 6808
• 6700

Specifications

• Standby Current: 21mA
• Alarm Current: 21mA
• Operating Voltage: 24VDC
• Operating Temperature: 32°F to 120°F (0°C to 49°C)

Installation

Layout and Mounting

The SK-NIC can be mounted within the FACP cabinet (except for the IFP-75 or 6700), in a 5815RMK accessory cabinet, or in a SK-NIC-KIT cabinet. Up to two SK-NIC cards can fit inside the 5815RMK. Refer to the 5815RMK Installation Document, P/N 151391.

The SK-NIC-KIT is an accessory cabinet kit containing an SK-NIC card, a small cabinet with door, a 6-pin cable and mounting hardware. Up to two SK-NIC cards can fit inside the SK-NIC-KIT. For more information, refer to the SK-NIC-KIT Installation Document P/N LS10171-001SK-E.

Figure 1: SK-NIC Board

The SK-NIC board features two ports labeled 'Port 1' and 'Port 2', a connector labeled 'P3', and other component placements. It is shown with a connection to the FACP.

Installation (Wiring)

NOTE: Installation and wiring of this device must be done in accordance with NFPA 72 and local ordinances.

Refer to the following steps to properly connect the SK-NIC to the FACP port using the supplied 6-pin cable.

1. Place the SK-NIC on one of the SLC expander standoff sets.
2. Using the 6-pin cable, connect one end to the FACP pin connector labeled "Data Network" and the other end to the SK-NIC board's P3 connector.

Figure 2: Panel to SK-NIC Connection

This diagram illustrates the connection between a Fire Alarm Control Panel (FACP) and the SK-NIC. A 6-pin cable connects the FACP's 'Data Network' connector to the SK-NIC's P3 connector. The FACP layout may vary. An optional conduit is shown for remote mounting.

SK-NIC Remote Mounting

Follow Steps 1 and 2 above except the 6-pin cable that runs from the SK-NIC to the FACP must be run in conduit. Refer to the SK-NIC-KIT or 5815RMK Installation Document.

Fiber Loop Modules

The SK-NIC connects to other networked units using unshielded, twisted-pair wiring or fiber-optic cable.

The SK-FML and SK-FSL are plug-in fiber loop modules. The two types of fiber optic modules are used as one channel to transmit or receive communications with the SK-NIC, ARCNET communication circuit.

The following two types of fiber-optic modules are available:

• The SK-FML is a fiber module that allows the multi-mode fiber to network between nodes.
• The SK-FSL is a fiber module that allows the single-mode fiber to network between nodes.

For more information on the fiber modules, refer to the SK-FML and SK-FSL Installation Document P/N:LS10178-001SK-E.

Figure 3: SK-NIC Fiber Loop Modules Mounted on SK-NIC

The SK-NIC board is shown with plug-in fiber loop modules, SK-FML and SK-FSL. It includes terminals for connecting to other units using copper wire instead of fiber modules. LED indicators (LED1, LED2) are also visible.
