NS Series Network Discharge Air Sensors

Installation Instructions

NS-DTN7043-0, NS-DTN7083-0
Applications
The NS Series Network Discharge Air Sensors are
electronic duct sensors designed to function directly
with Johnson Controls® digital controllers in Heating,
Ventilating, and Air Conditioning (HVAC) systems.
Models in this series monitor the duct temperature,
typically at the discharge of the Variable Air
Volume (VAV) box, and transmit this data to the
controller Sensor Actuator (SA) Bus using the
305 cm (10 ft) wiring lead included with the unit. The
305 cm (10 ft) wiring lead consists of four
0.6 mm (22 AWG) diameter 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 102 or 203 mm (4 or 8 in.)
temperature probe. All models include DIP switches for
applications requiring multiple discharge air sensors,
each with a unique DIP switch address.
IMPORTANT: The NS Series Network Discharge
Air Sensors are intended to provide an input to
equipment under normal operating conditions.
Where failure or malfunction of the discharge air
sensors 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
discharge air sensors.

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 is
likely to cause harmful interference, in which case
the user will be required to correct the interference
at his/her own expense.
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.
Mounting
The following ambient operating conditions apply:
• Temperature: -10 to 60°C (14 to 140°F)
• Humidity: 10 to 90% Relative Humidity (RH),
noncondensing; 29°C (85°F) maximum dew point
Note: The discharge air 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.
