NS Series Flush-Mount Network Sensors Installation Instructions 1
Applications
The NS Series Flush-Mount Network Sensors are
wall-mounted temperature sensors designed for use
with Johnson Controls® digital controllers in Heating,
Ventilating, and Air Conditioning (HVAC) systems.
Models in this series monitor the space temperature,
typically in a room, and transmit this data to a Field
Equipment Controller (FEC), a Variable Air Volume
(VAV) Modular Assembly (VMA) 16, or a Network
Control Engine (NCE) on the Sensor Actuator (SA)
Bus. The wires connecting the network sensor to the
controller must be terminated using the screw terminal
block on the flush-mount sensor module.
The wall sensors include DIP switches for applications
requiring multiple flush-mount sensors, each with a
unique DIP switch address.
IMPORTANT: The NS Series Flush-Mount Network
Sensor is intended to provide an input to equipment
under normal operating conditions. Where failure or
malfunction of the flush-mount 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 flush-mount sensor.
IMPORTANT : Le NS Series Flush-Mount 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 flush-mount 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 flush-mount
sensor.

Mounting
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
Note: The flush-mount network sensors are shock
and vibration resistant; however, be careful not to drop
the unit or mount them where they could be exposed to
excessive vibration.
Location Considerations
Consider the following mounting location guidelines:
• Avoid areas subject to excessive vibration,
electrical noise, direct sunlight, or the effects of
radiant heat.
Mounting the Flush-Mount Network Sensor
Mount the temperature sensor as follows:
1. Remove the appropriate knockout on the standard
utility conduit box for the application.
2. Remove the faceplate and SA Bus board. The
SA Bus board is enclosed inside the
non-conductive pouch.
3. Suspend the faceplate from the utility box using the
supplied rubber band. This action ensures that the
weight of the faceplate does not pull on the SA Bus
board when you make the wiring connections.
4. Make SA Bus wiring connections to the sensor
electronics module. Table 1 describes the terminal
designations.
5. Install the electronics board inside of the
non-conductive pouch. Fold the pouch and place it
inside the electrical utility box (Figure 1).
Note: The non-conductive pouch is designed and
sized to protect the electronic equipment from
secondary electrostatic discharge. Do not cut or modify
the pouch. Ensure that the electronics module is fully
inserted down to the bottom, and that the pouch end is
folded as instructed.
Note: Level the sensor for appearance; however, the
sensor functions normally when not level.
6. Mount the sensor to the wall box or electrical box
using the screws provided.
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 is
likely to cause harmful interference, in which case
the user will be required to correct the interference
at his/her own expense.
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.

7. Use the Controller Configuration Tool (CCT)
software to commission the flush-mount sensor.
Refer to the CCT Help for more details.
Wiring
If the NS Series Flush-Mount Network Sensor is used
in an application requiring multiple temperature
sensors, each with a unique DIP switch address, set
the DIP switches before wiring the unit.
Network Sensor Addressing
Most network sensors have a default device address of
199 on the SA Bus.
Averaging models are shipped with both switches set
to ON, resulting in a device address of 203. Device
addresses can be DIP switch set from 200 to 203; see
Figure 3 and Table 2 for more details.
Table 2 lists the available DIP switch addresses and
the DIP switch settings required to obtain them.
Figure 2 shows how to wire the flush-mount sensor to
the SA Bus screw terminal block.
Note: For more details on wiring the MS/TP
Communications Bus, refer to the MS/TP
Communications Bus Technical Bulletin
(LIT-12011034).
Repair Information
If the NS Series Flush-Mount Network Sensor fails to
operate within its specifications, replace the unit. For a
replacement flush-mount sensor, contact the nearest
Johnson Controls representative.
