Product Description

The Wireless Field Level Network Transceiver
(FLNX) is mounted at or near the FLN device and is
powered by 24 Vac. The antenna can be mounted
directly to the radio or mounted remotely for
installations where the location of the FLNX causes
the antenna to be shielded—for example, when the
FLNX is mounted inside a TEC enclosure.

Installation Instructions

Prerequisites

• FPX for the WFLN is installed and powered.
The FPX generates the PAN ID, which is
needed for WFLN communications.

• All wiring must conform to NEC and local
codes and regulations.

• 24 Vac Class II power source is available.

• Metal Oxide Varistors (MOVs) must be used

for TECs that switch high voltage devices.

For details, see the FSN for Terminal

Equipment Controllers (TECs) Failing when
Switching High Voltage Powered Devices.

• Any application specific hardware or device
is installed.

Antenna Mounting

VAV BOX

VAV BOX

Direct Mount Antenna

The preferred mounting configuration is to mount the
FLNX outside the TEC enclosure in a location where
it will establish the maximum number of
communication links with other FLNXs and its
associated FPX. For example, in a VAV application
this is typically on the bottom of the VAV box in the
ceiling plenum, with the entire antenna extending
downwards below the VAV box (Figure 2).

Remote Mount Antenna

The FLNX is mounted inside the TEC, or any metal
enclosure, and the antenna is brought through a
1/2 in. (1.3 cm) knockout (Figure 3).

The antenna extension cable is 12 in.
(30 cm) long.

The cable for the remote mount antenna
will cause a slight reduction in the FLNX’s
power and range, compared to using a
direct mount antenna.
