Applications
The vertical wallbox-mounted or surface-mounted occupancy sensing NS Series Network Sensor with LCD is an
electronic zone sensor designed to function directly with Johnson Controls® BACnet® Master-Slave/Token-
Passing (MS/TP) digital controllers in HVAC systems. Models in this series monitor the temperature setpoint and
zone temperature, and transmit this data to a field controller on the Sensor Actuator (SA) Bus.
All 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, residence halls, 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.
An LCD and, depending on the model, either a temperature setpoint dial or setpoint adjustment buttons are
featured on all models to make adjusting the temperature setpoint and viewing the zone temperature easier.
A °F/°C pushbutton is available on all models to provide temperature scale options for display. An occupancy
override function is featured on all models, which allows you to signal the controller that the space is occupied or to
request an override of time-of-day scheduling. Rotating the setpoint dial or pressing either setpoint adjustment
button signals occupancy. See Temperature Setpoint Adjustment/Occupancy Override
for more information.
Depending on the model chosen, you can terminate the wires that connect the network sensor to the controller
using either a modular jack or screw terminal block, which offers wiring flexibility.
Note: The model featuring a modular jack is not intended for installations where daisy chaining to the MS/TP Bus
is required.
All models include an SA Bus access port for connecting accessories to access the SA Bus. This feature allows a
technician to commission or service the controller through the network sensor.
Note: Since some NS Series Network Sensor features are not supported in previous releases of Metasys® or
Facility Explorer system software, we recommend that you keep the system software up to date.
IMPORTANT: The occupancy sensing 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.
IMPORTANT: Le occupancy sensing NS Series Network Sensor est destiné à transmettre des données
entrantes à un équipement dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou un
dysfonctionnement du network sensor risque de provoquer des blessures ou d'endommager l'équipement
contrôlé ou un autre équipement, la conception du système de contrôle doit intégrer des dispositifs de protection
supplémentaires. Veiller dans ce cas à intégrer de façon permanente d'autres dispositifs, tels que des systèmes
de supervision ou d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction d'avertissement ou
de protection en cas de défaillance ou de dysfonctionnement du network sensor.

Location Considerations
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
• in a clear path between the PIR occupancy sensor and the space being monitored
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.

Setup and Adjustments
Temperature Setpoint Adjustment/Occupancy Override
Depending on the model, you can use either the large temperature setpoint adjustment dial or the temperature
setpoint adjustment buttons on the face of the network sensor to change the controller mode from unoccupied to
occupied, or to adjust the temperature setpoint.
To change the occupancy mode using the dial, rotate the dial slightly, so the backlight on the LCD lights up. If you
rotate the dial slightly again and the controller is in the unoccupied mode, the controller changes from the
after-normal-working-hours setback mode to the normal-working-hours comfort mode. Alternatively, you can use
the pushbuttons to change the controller mode from unoccupied to occupied.
To adjust the setpoint using the dial, continue rotating the dial until the current setpoint is displayed and flashing.
Turn the dial clockwise to increase the setpoint and counterclockwise to decrease the setpoint. Stop turning the dial
once the preferred setpoint is reached. The new setpoint stops flashing and becomes fixed after a few seconds. To
use the pushbuttons instead, press the up arrow button to increase the setpoint or the down arrow to decrease it.
°F/°C Temperature Mode Selection
All models include a °F/°C pushbutton on the face of the network sensor to provide temperature scale options for
display. Pressing the pushbutton toggles the temperature mode between Fahrenheit and Celsius on the LCD.
Network Sensor Addressing
All occupancy sensing NS Series Network Sensors with LCD have a default device address of 199 on the SA Bus.
Repair Information
If the occupancy sensing NS Series Network Sensor fails to operate within its specifications, replace the unit. For a
replacement network sensor, contact the nearest Johnson Controls representative.
