NS Series Network Sensors

Code No. LIT-1900350

Issued June 26, 2013

Description

The NS Series Network Sensor offering includes NS Series Network

Zone Sensors and NS Series Network Discharge Air Sensors. The

NS Series Network Sensors are designed to function directly with

Metasys® system Field Equipment Controllers (FECs), Input/Output

Modules (IOMs), Variable Air Volume (VAV) Modular Assembly

(VMA16) Controllers, and Facility Explorer FX-PC Series

Programmable Controllers (FX-PCGs, FX-PCVs, and FX-PCXs).

The majority of NS Series Network Zone Sensors monitor room

temperature; however, options are available to also monitor zone

humidity, carbon dioxide (CO

), local temperature setpoint

adjustments, and other variables. This data is transmitted to a

controller on the Sensor Actuator (SA) Bus.

Some models of NS Series Network Zone Sensors 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.

The NS Series Network Zone Sensors include models with a

temperature setpoint dial and Liquid Crystal Display (LCD) that allows

occupants to view the zone temperature, Relative Humidity (RH), and

view and adjust the zone temperature setpoint. Some temperature and

humidity 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 fan mode push button is included to set the desired fan speed

(AUTO-OFF-low-medium-high). An occupancy override function

allows the user to signal the controller that the zone is occupied to

override the scheduled mode. Some models have DIP switches to set

a unique address for applications that require multiple sensors.

For communication wiring flexibility, the wires connecting the network

zone sensor to a controller can be terminated using a modular jack or

screw terminals.

Each network sensor includes an SA Bus access port to allow

accessories to access the SA Bus. This plug allows accessories to

service or commission the connected controller or gain access to any

other controller on the same Field Controller (FC) Bus.

The NS Series Network Zone Sensor offering includes models that can

be surface mounted, vertical wallbox mounted, or flush mounted to

meet the requirements of the specific application.

The NS Series Network Discharge Air Sensors monitor the duct

temperature, typically at the discharge of the VAV box, and transmit this

data to a local controller on the SA Bus using the 10 ft (305 cm) wiring

lead included with the unit. The 10 ft (305 cm) wiring lead consists of

four 22 AWG (0.6 mm) trade size color-coded wires encased in a

plenum-rated jacket. Each of the wires is stripped and tinned for easy

connection to the SA Bus screw terminal block.

The NS Series Network Discharge Air Sensors are available with either

a 4 or 8 in. (102 or 203 mm) temperature probe. All models include DIP

switches for applications requiring multiple discharge air sensors, each

with a unique DIP switch address.

NS Series Network Sensors

Features

• BACnet® Master-Slave/Token-Passing (MS/TP) protocol

communication — provides compatibility with Metasys system field

controllers and Facility Explorer programmable controllers in a

proven communication network

• backlit Liquid Crystal Display (LCD) available on some models —

provides real-time status of the environment with backlighting

activated during user interaction

• simple temperature setpoint adjustment available on some

models — enables you to change the setpoint with the turn of a dial

• onboard PIR occupancy sensor available on some models —

maximizes up to 30% energy savings in high-energy usage

environments, and facilitates trending of floor space usage

• temporary occupancy available on some models — provides a

timed override command, which temporarily initiates an alternate

mode

• field selectable default display setting on some models — allows

you to toggle between temperature and RH on the display, and set

the desired default for continuous viewing

• Fahrenheit/Celsius (F/C) button available on some models —

toggles the display temperature between degrees Celsius and

degrees Fahrenheit

Repair Information

If the NS Series Network Zone Sensor or the NS Series Network

Discharge Air Sensor fails to operate within its specifications, replace

the unit. For a replacement sensor, contact the nearest

Johnson Controls® representative.
