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.

10. Align the tabs on the bottom edge of the mounting
base with the slots on the bottom edge of the
network sensor assembly, and rotate the assembly
onto its mounting base.
Note: On models featuring a screw terminal
block, be certain that the terminal block pins
align with the holes in the terminal block.
11. Use a 1/16 in. (1.5 mm) Allen wrench or Johnson
Controls T-4000-119 Allen-Head Adjustment Tool to
tighten the security screw and fasten the network
sensor assembly to the mounting base.
Note: Do not overtighten the security screw to
avoid damaging the unit.
12. Before use, clean the lens of the PIR occupancy
sensor with a soft, dry cloth.
Note: Do not use water or other solvents to
clean the lens.
13. Use the Metasys Controller Configuration Tool
(CCT) or Facility Explorer Programmable Controller
Tool (FX-PCT) software to commission the
network sensor. Refer to the Controller Tool Help
(LIT-12011147) for more details.

Setup and Adjustments

Occupancy Override
Some models include an occupancy override push button
on the left side of the network sensor, inline with the
green LED. If the green LED is illuminated, the network
sensor is in the occupancy override mode. If the green LED
is not illuminated, pressing the occupancy override push
button activates the normal-working-hours comfort mode.
Some NS-series sensor models also include a PIR
Occupancy Sensor, or can initiate occupancy by rotating
the setpoint dial. The LED is not illuminated when the PIR
sense occupancy or the setpoint dial is rotated.
Network Sensor Addressing
Most occupancy sensing NS Series Network Sensors have
a default device address of 199 on the SA Bus. For the NS-
MNN7003-0 model, the sensor address must be set on
the dual-switch DIP switch block on the network sensor
Printed Wire Board (PWB).
