Introduction to the 4100 NIC
The NIC is a slave card that uses the standard 4100 serial bus to communicate with the master. The NIC connects FACPs in a network, allowing
communication between each panel via fiber, modem, or twisted shielded pair wire in a Class X wiring configuration.
The NIC is designed to be connected in a point-to-point arrangement, so one wire fault does not cause the entire system to fail. The point-to-point
arrangement provides the most secure and fault- tolerant wiring possible.
Two types of media boards can be used with the NIC.
• The Fiber-Optic Media Card can be used for electrically noisy environments or for connecting externally to other buildings.
• Non-4100U/4100ES only: the Modem Media Card is typically used when a large transmission distance is required.
The Wired Media Card is used in all other types of applications.
Up to two media boards can be plugged into each NIC. The same NIC can use a combination of two types of media boards (for example, a NIC may
have a wired media card connected to port 1 and a fiber-optic media card connected to port 2).
