Installation Instructions
March 12, 2008
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
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.
