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® BACnet®Master-Slave/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.
