Applications

The surface-mounted NS Series Network Sensor
without 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 zone temperature and humidity, and
transmit this data to a field controller on the Sensor
Actuator (SA) Bus.

A warmer/cooler dial is included on certain models for
minor temperature adjustments from the setpoint. An
occupancy override button is also featured on some
models, which allows the user to signal the controller
that the space is occupied, to request an override of
time-of-day scheduling. Rotation of the warmer/cooler
dial signals occupancy as well. Select models include
DIP switches to set a unique address in averaging
applications. Models are available with or without a
Johnson Controls logo on the face of the unit.

Depending on the model chosen, the wires connecting
the network sensor to the controller can be termin at ed
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.

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 con tr ôle
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

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.

Instructions

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

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 cab le fro m 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.

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.

5. Secure the mounting base to the wall using the appropriate mounting hardware (field furnished).

6. 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 models featuring a modular jack, simply snap the wiring plug into the jack. See Figure 1 for modular jack

!

pin number assignments. Modular jack models require a straight-thr ough, one-to-one connection (not a
crossover). For models featuring a screw terminal block, wire the unit as illustrated in Figure 2.

CAUTION: Risk of Electric Shock.

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

MISE EN GARDE : 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 Variable
Air Volume (VAV) balancing tool, and you will not be able to expand the system with future offerings.
