NS8000 Series
Vertical Wallbox-Mounted or Surface-Mounted NS Series Network Sensors
Product Bulletin
Overview
The NS Series Network Sensors function directly with
Metasys® system Field Equipment Controllers (FECs),
Metasys Network and Control Engines (NCEs), Advanced
Application Field Equipment Controller (FACs), Metasys VAV
Box Equipment Controllers (CVM), General Purpose Application
Controllers (CGM), Input/Output Modules (IOMs), VAV Modular
Assembly (VMA16) Controllers, and Facility Explorer™ FX-PC
Series Programmable Controllers (FX-PCGs, FX-PCVs, and
FX-PCXs). The sensors are also compatible with Verasys® and
Johnson Controls® Smart Equipment.
The NS Series Network Sensors monitor zone temperature,
relative humidity, carbon dioxide (CO2), motion, and local
temperature setpoint adjustments. The sensor transmits this
data to a controller on the Sensor/Actuator (SA) bus.
Some NS Series Network Sensors models include an onboard
passive infrared (PIR) occupancy sensor that detects motion
to determine if a space is occupied. This feature maximizes
up to 30% energy savings in high-energy usage environments
such as schools, dormitories, offices, hospitals, and hotels by
adjusting the temperature of the space based on the occupancy
status. In addition, the PIR occupancy sensor facilitates
trending of floor space usage in these environments.

Issue Date May 2019
The user can use the occupancy override function to signal
to the controller that the zone is occupied and to override the
scheduled mode.
Some models also have a Warmer/Cooler interface to adjust
the zone temperature. Instead of a display, these models have
two cap touch buttons with seven LED lights that represent the
current setpoint.
All models have DIP switches to set a unique address for
applications that require multiple sensors. For communication
wiring flexibility, they also include both modular phone jacks,
and screw terminals to terminate the wiring connecting the
sensors to the controller.
Note: To connect the NS Series Network Sensor to the same
SA bus segment, use only one of the two connection methods,
either the modular phone jack or the screw terminals.
Each network sensor includes a SA bus access port,
allowing for accessories to connect to the SA bus. Through
this connector, the user can use accessories to service or
commission the connected controller or gain access to any
other controller on the same field controller (FC) bus.
Some models of the NS Series Network Sensors include a
touch display to view zone temperature, RH, CO2, and adjust
the zone temperature setpoint and fan speed. These models
have the capability to set the default display to temperature,
RH, or temperature setpoint. On these display models the user
can also choose between degrees Fahrenheit (F) and degrees
Celsius (C). To prevent tampering with the sensor, display
models also include a screen lockout feature.
The display models include the following fan speeds:
• Automatic
• Off
• Low
• Medium
• High
The NS Series Network Sensors can be surface mounted
or vertical wallbox mounted to meet the requirements of the
specific application. All display models are optimized for the
California Energy Code (Title 24). To suit specific architectural
and interior design needs, all models come with either black or
white enclosures.
All sensors are serialized for quality and warranty purposes.
Based on the serial number, the user can obtain factory
calibration certificates.

NS8000 Series
Modern enclosures in black or white design themes are
available in the following three styles:
• LCD fixed segment display: View zone temperature, RH,
CO2, occupancy status, and adjust the zone temperature
setpoint and fan speed. These models have the
capability to set the default display to temperature, RH or
temperature setpoint. On these display models, you can
also choose between degress Fahrenheit (F) and degrees
Celsius (C).
• Warmer/Cooler interface: This interface incorporates cap
touch buttons with seven LED lights that represent the
current setpoint status.
• No display: The NS Series Network Sensors are available
in high gloss black or white with or without the Johnson
Controls logo.

IMPORTANT
The NS Series Network Sensor is intended to provide an input to equipment under normal operating conditions. Where failure
or malfunction of the network sensor could lead to personal injury or property damage to the controlled equipment or other
property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as
supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the
network sensor.
Note: Keep the system software up to date as some NS Series Network Sensor features are not supported in previous releases of
Metasys, Facility Explorer, Verasys, or Johnson Controls Smart Equipment system software.
Repair information
If the NS Series Network Sensor fails to operate within its specifications, replace the unit. For a replacement sensor, contact the
nearest Johnson Controls representative.

Technical specications
Supply voltage 9.8 VDC to 16.5 VDC; 15 VDC nominal (from SA bus)
Current consumption Base current draw (all models) 3 mA maximum (non-transmitting)
CO2 models 15 mA maximum additional current (during measurement)
Display models - backlight on 10 mA additional current
Warmer/Cooler models - LEDs on 8 mA additional current
Note: SA bus applications are limited to a power load of 210 mA. The best practice when configuring an
SA bus is to limit the total available operating power consumption to 120 mA or less. This power level
allows you to connect a BTCVT Wireless Commissioning Converter temporarily or a DIS1710 Local
Controller Display to the bus for commissioning, adjusting, and monitoring.
