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.
