Silent Knight SK-NIC — network interface card that ties Silent Knight panels onto one common communications and annunciation link.
A building outgrows one panel long before it outgrows one account. The SK-NIC gives each panel an ARCNET node so up to 17 panels share status and one designated panel handles offsite communication, instead of a dialer and phone line at every cabinet. An SK-FML or SK-FSL plug-in module converts a node to fiber.
- Links up to 17 panels; for 6700, 6808, 6820, 6820EVS
- 24 VDC; 21 mA standby, 21 mA alarm; 32° to 120°F
- 16 to 18 AWG unshielded twisted pair, up to 3,000 ft between nodes; Class A or Class B
- 625K baud ARCNET repeater; UL 864 10th Ed. and UL 2572 2nd Ed.
This is a common communications link, not peer-to-peer networking — linked panels cannot pass control to one another. On a 6700 the card cannot sit inside the panel cabinet and the SK-NIC-KIT is required.

FAQ
Which panels can use the SK-NIC?
The Silent Knight 6820, 6820EVS, 6808 and 6700 fire alarm control panels.
How many panels can be linked?
Up to 17 panels, with one designated panel acting as the communicator for all panels in the link.
Can linked panels control each other?
No. The SK-NIC provides a common communications link; the panels cannot be linked for peer-to-peer networking.
Can the network run on fiber?
Yes. Optional single-mode and multi-mode fiber-optic add-on modules are available; standard connections use unshielded twisted-pair copper.
