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/Token­Passing (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 sen sor that detects motion to de termine if a space
is occupied. This feature maximizes up to 30% energy savings in high-energy usage environmen ts 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 th e controller that the sp ace 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

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.

for more information.

Note: The model featuring a modular jack is not i ntended fo r 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 senso r.

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 equipmen t
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 limit ation, ayant une fonction d'avertisseme nt ou
de protection en cas de défaillance ou de dysfonctionnement du network sensor.

North American Emissions Compliance

United States

This equipment has been tested and found to comply with the limits for a Class A digital device pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when this equipment is operated in a commercial environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not inst alled a nd used in accordan ce with the instruction manual,
may cause harmful interference to radio communications. Operation of this equipment in a residential area may
cause harmful interference, in which case users will be required to correct the interference at their own expense.

Canada

This Class (A) digital apparatus meets all the requirements of the Canadian Interference-Causing Equipment
Regulations.

Cet appareil numérique de la Classe (A) respecte toutes les exigences du Règlement sur le matériel brouilleur
du Canada.

Installation

Special Tools Needed

A 1/16 in. (1.5 mm) Allen wrench or a Johnson Controls T-4000-119 Allen-Head Adjustment Tool is required during
installation.

Mounting

Note: For wallbox-mounted installations, the occupancy sensing 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.

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.

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 cab le fro m the wallbo x an d ins er t the cab le th ro ug h the ho le 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 in cluded 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 the model featuring a modular jack, simply snap the wiring plug into the jack. See Figure 1 for modular jack
pin number assignments. The modular jack model requires a straight- through, one-to-one connection (not a
crossover). For the model featuring a screw terminal block, wire the unit as illustrated in Figure 2.

Risk of Electric Shock.

Disconnect the power supply before making electrical connections to avoid electric shock.

Risque de décharge électrique.

Débrancher l'alimentation avant de réaliser tout raccordement électrique afin d'éviter tout risque de décharge
électrique.

IMPORTANT: Failure to adhere to these wiring details causes the ne twork sensor to function incorrectly. You
will not be able to connect to the system using the wireless commissioning converter or the handheld VAV
balancing tool, and you will not be able to expand the system with future offerings.
