NSB8BHC341-0 Johnson Controls Network Sensor

Overview

The Johnson Controls NSB8BHC341-0 is a next-generation NS8000 Series Network Sensor designed to function directly with building automation controllers, including Metasys and Facility Explorer systems. This multi-functional, wall-mounted sensor reduces wall clutter by consolidating environmental monitoring into a single device that transmits data over a Sensor/Actuator (SA) bus. It features a modern industrial design in white, without a exterior Johnson Controls logo, and includes a full-color graphical LCD user interface.

Features

• Multi-functional sensing capable of monitoring zone temperature, 3% relative humidity (RH), and carbon dioxide (CO2) levels.
• Full-color graphical LCD interface that provides a real-time summary of environmental values and supports custom user adjustments.
• Customizible user options including a screen lockout to prevent tampering, selectable light or dark color themes, and dimming or turning off sleep modes.
• Integrated fan speed controls offering automatic, off, low, medium, or high settings.
• Temporary occupancy override functionality allowing users to signal to the controller that the zone is active, altering scheduled modes.
• Flexible addressing options via the graphical user interface to set a unique BACnet address, simplifying multi-sensor applications.
• Easy installation with standard modular phone jacks and screw terminals for quick wiring to the controller.
