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/Token-
Passing (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 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, 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 the controller that the space 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
for more information.
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.
Note: The model featuring a modular jack is 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 through the network sensor.
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 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.
