Applications

The surface-mounted 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 Heating, Ventilating, and Air Conditioning
(HVAC) systems. Models in this series monitor the
temperature setpoint, zone temperature, and humidity,
and transmit this data to a field controller on the Sensor
Actuator (SA) Bus.

All models feature a temperature setpoint dial and
LCD designed to make adjusting the temperature
setpoint and viewing the zone temperature easier.
A warmer/cooler dial is included on certain models for
minor temperature adjustments from the setpoint.

Some models allow occupants to view the
Relative Humidity (RH) of the zone; these models
include a push button to toggle between temperature
and RH on the display. These models also have the
capability to set the desired default display to either
temperature or RH.

A °F/°C push button is available on certain models
to provide temperature scale options for display.
A fan mode push button is also included on some
models to select the desired fan speed
(AUTO-OFF-low-medium-high). An occupancy
override function is featured on all models, which
allows the user to signal the controller that the sp ace is
occupied, to request an override of time-of-day
scheduling. Rotating the setpoint dial signals
occupancy. See Temperature Setpoint Adjustment/
Occupancy Override for more information.

Select models in this series also provide Variable Air
Volume (VAV) balancing functionality. These models
look like and perform similarly to the other network
sensors but have the added capability of serving as a
tool to balance a VAV box.

Depending on the model chosen, the wires connecting
the network sensor to the controller can be terminated
using either a modular jack or screw terminal block,
offering wiring flexibility.

Note: Models featuring a modular jack are 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 via the network sensor. Select models
offer stylish black enclosures to suit specific
architectural and interior design needs.

Note: Since some NS Series Network Sensor
features are not supported in previous releases of
Metasys® or Facility Explorer system software, it is
recommended that the system software be kept up to
date.

IMPORTANT: The surface-mounted 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 surface-mounted 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.

North American Emissions Compliance

Mounting

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 installed and used in
accordance 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 the
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.

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

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 to the wall:

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. Pull out approximately 6 in. (152 mm) of cable from
the wall, and insert the cable through the hole in
the mounting base.

4. 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.
