4-NET-TP(-HC) Twisted Pair
SFP Network Controller
Installation Sheet
Description
The 4-NET-TP(-HC) Small Form-factor Pluggable (SFP) network
controllers support audio and data communication over a single
twisted wire pair. Each controller supports a single wire pair
connection. The 4-NET-TP(-HC) to 4-NET-TP(-HC) link is supervised
for opens, shorts, ground faults, and continued communications.
The 4-NET-TP supports all command and control, live and recorded
audio functions, and live firefighters telephone network functions.
The 4-NET-TP-HC supports all command and control, live and
recorded audio functions.
4-NET-TP series network controllers plug into one SFP slot in the
4-CPU, 4-ANNCPU, 4-CPUGRPH, or 4-NET-AD modules.
Installation
Install and wire this device in accordance with applicable national and
local codes, ordinances, and regulations.
Caution: Equipment damage hazard. This product is sensitive to
electrostatic discharge (ESD). To avoid damage, follow accepted ESD
handling procedures.
Note: When stripping wire ends, exposing more wire may cause a
ground fault; exposing less wire may result in a faulty connection. Strip
0.35 in. (9 mm) from the ends of all wires that connect to the
4-NET-TP(HC).
To install the SFP network controller:
1. Make required connections. Refer to Wiring.
Push the wire into the holes in the controller shown in Figure 1.
Gently pull the wires to make sure that you cannot remove them.
2. Close the bale clasp (Figure 1), and then insert the SFP network
controller until you feel the network controller is seated into the
connector (Figure 2). Firmly press the SFP network controller into
the slot until it latches (clicks).
3. Without releasing the bale clasp, gently pull the SFP network
controller to make sure that you cannot remove it.
Notes
•Depending on the installation, it might be easier to remove the
wires from the controller after the controller is removed from the
module.
•Small Form-factor Pluggable (SFP) network adapters are hot-
swappable.
To remove the SFP network controller:
1. Open the bale clasp.
2. Gently pull the SFP network controller out of the SFP slot by
pulling on the open bale clasp.
3. Press both wire release buttons using a #6 (1/8 in. span) spanner
tool, and then remove the wires from the 4-NET-TP(-HC). See
Figure 3.

Wiring
Network data and network audio circuit wiring are supervised and
power-limited. The wiring connections on the 4-NET-TP(HC) are not
polarity sensitive.
Supported wiring styles include:
•Class A
•Class B
•Class X
•Mesh networking topology
Pass-through from the CPU module eth1 and eth0 network
connections is supported from the 4-NET-TP(HC) to any other SFP
type, with the exception of a 4-NET-TP to a 4-NET-TP-HC connection,
which is not supported. Pass-through mode does not limit individual
wire run lengths. Refer to the control unit Technical Reference Manual
for details.
