Mounting
About this task:
Note: For wallbox-mounted installations, the NS
Series Network Sensor is intended to be mounted on
a vertically roughed-in wallbox only; do not attempt
to mount the network sensor on a horizontally
roughed-in wallbox.
Locate the network sensor:
• on a partitioning wall, approximately 5 ft (1.5 m) above
the floor in a location of average temperature
• away from direct sunlight, radiant heat, outside walls,
outside doors, air discharge grills, or stairwells; and
from behind doors
• away from steam or water pipes, warm air stacks,
unconditioned areas (not heated or cooled), or sources
of electrical interference
Note: The network sensor is shock and vibration
resistant; however, be careful not to drop the unit
or mount it where it could be exposed to excessive
vibration.
The following ambient operating conditions apply:
• Temperature: 32 to 104°F (0 to 40°C)
• Humidity: 10 to 90% Relative Humidity (RH),
noncondensing; 85°F (29°C) maximum dew point
To mount the network sensor:
1. Use a 1/16 in. (1.5 mm) Allen wrench or Johnson
Controls T-4000-119 Allen-Head Adjustment Tool to
loosen the security screw on the top of the unit.
2. Insert a coin into the slot next to the security screw
location, then carefully pry the top edge of the
sensor assembly away from its mounting base and
remove.
Important: Do not remove the Printed Circuit
Board (PCB). Removing the PCB voids the
product warranty.
3. For vertical wallbox-mounted installations, proceed
to Step 4. For surface-mounted installations,
proceed to Step 7.
4. Pull out approximately 6 in. (152 mm) of cable from
the wallbox, and insert the cable through the hole
in the mounting base.
5. Align the mounting base on the wallbox.
Note: Confirm that the mounting base is
positioned with the proper edge up. The
mounting base is positioned properly when the
security screw is located on the top edge of the
base.

6. Secure the mounting base to the wallbox using the
two No. 6 pan-head mounting screws included with
the unit. Proceed to Step 9.
7. Align the mounting base on the wall, and use the
base as a template to mark the location of the two
mounting holes on the surface.
Note: Confirm that the mounting base is
positioned with the proper edge up. The
mounting base is positioned properly when the
security screw is located on the top edge of the
base.
8. Secure the mounting base to the wall using the
appropriate mounting hardware (field furnished).
Proceed to Step 9.
9. Wire the network sensor. For more details on wiring
the MS/TP Communications Bus, refer to the MS/TP
Communications Bus Technical Bulletin (LIT-12011034)
or the FX-PC Series Controllers MS/TP Communications
Bus Technical Bulletin(LIT-12011670).
For models featuring a modular jack, simply
snap the wiring plug into the jack. See Figure
1 for modular jack pin number assignments.
Modular jack models require a straight-through,
one-to-one connection (not a crossover). For
models featuring a screw terminal block, wire
the unit as illustrated in Figure 2.
CAUTION
Electric Shock.Disconnect the power supply before
making electrical connections to avoid electric shock.

Important: Failure to adhere to these wiring
details causes the network sensor to function
incorrectly. You will not be able to connect to
the system using the wireless commissioning
converter or the handheld Variable Air Volume
(VAV) balancing tool, and you will not be able to
expand the system with future offerings.
