Johnson Controls NS Series Installation Manual

Applications
The vertical wallbox-mounted or surface-mounted
occupancy sensing NS Series Network Sensor without
LCD is an electronic zone sensor designed to function
directly with Johnson Controls
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.
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, dormitories, 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.
Note: The NS-MNN7001-0 and NS-MNN7003-0
models do not include a temperature or humidity
sensor, and only detect motion in the zone.
An occupancy override button is 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. One model includes DIP switches to set a
unique address in averaging applications.
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.
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 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. Approved

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.
Warning (Part 15.21)
Changes or modifications not expressly approved by the
party responsible for compliance could void the user's
authority to operate the equipment.
Canada
This Class (A) digital apparatus meets all the requirements
of the Canadian Interference-Causing Equipment
Regulations.
