Applications
The NS Series Network Discharge Air Sensors are
electronic duct sensors designed to function directly
with Johnson Controls® digital controllers in 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.
IMPORTANT : Le NS Series Network Discharge Air
Sensors est destiné à transmettre des données
entrantes à un équipement dans des conditions
normales de fonctionnement. Lorsqu'une défaillance
ou un dysfonctionnement du discharge air sensors
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 discharge
air sensors.
