NSB8MTN041-0 Johnson Controls Network Sensor

Overview

The Johnson Controls NSB8MTN041-0 is a wall-mounted network sensor from the NS8000 Series designed to function directly with Metasys system controllers, Facility Explorer programmable controllers, and Verasys or Smart Equipment. This model features a clean white enclosure without a logo and does not include a local display interface. It incorporates advanced sensing technologies to monitor room conditions and transmit data over a Sensor/Actuator (SA) bus, helping to optimize HVAC system performance and reduce installation costs.

Features

• Network communication via BACnet MS/TP protocol over the Sensor/Actuator (SA) bus.
• Integrated temperature sensor for precise zone monitoring.
• Onboard passive infrared (PIR) occupancy sensor that detects motion to enable demand-driven control strategies.
• Generates up to 30% energy savings in high-usage environments by adjusting HVAC status based on occupancy.
• Facilitates trending and analysis of floor space utilization.
• Clean industrial design without a manufacturer logo to seamlessly blend into commercial spaces.
• Built-in addressable capabilities via DIP switches for configurations requiring multiple sensors on a single bus.
• Ships standard with both modular phone jacks and screw terminal blocks for versatile wiring terminations.

Specifications

• Supply Voltage: 9.8 VDC to 16.5 VDC (15 VDC nominal supplied from the SA bus).
• Current Consumption: 3 mA maximum base current draw (non-transmitting).
• Temperature Sensor: Yes.
• Humidity Sensor: No (0% RH capability on this specific model variant).
• CO2 Sensor: No.
• Local Display: No display interface.
• Local Setpoint Adjustment: None.
• Fan Control: No.
• PIR Occupancy Sensor Range: Minimum 94 angular degrees up to a distance of 16 feet (5 meters).
• Enclosure Color: White.
• Logo: None (No JCI logo).
• Wiring Connections: Modular Jack and Terminal Strip.

Applications

• Commercial HVAC zone temperature monitoring and building automation integrations.
• High-energy usage environments requiring automated efficiency, such as schools, dormitories, offices, hospitals, and hotels.
• Spaces where tenant tampering must be eliminated by utilizing a non-display, non-adjustable sensor profile.
• Predictive maintenance and space utilization tracking via PIR occupancy trending data.
