NS-FTN7003-2 Johnson Controls Sensor

Overview

The Johnson Controls NS-FTN7003-2 is a flush-mount network zone temperature sensor designed to work directly with digital HVAC controllers such as the Metasys system Field Equipment Controllers (FECs), Advanced Application Field Equipment Controllers (FACs), Variable Air Volume Modular Assemblies (VMAs), and Facility Explorer FX-PC Series Programmable Controllers. This model monitors space temperature and transmits data over the Sensor Actuator (SA) Bus, offering a clean aesthetic without a visible brand logo or display.

Features

• Network communication via BACnet Master-Slave/Token-Passing (MS/TP) protocol over the SA Bus.
• Flush-mount design allows for low-profile installation directly into a wall or electrical box.
• No display and no logo configuration provides a discreet appearance suitable for diverse architectural environments.
• Addressable sensor capability utilizing onboard DIP switches to easily configure unique device addresses (200 to 203) for multi-sensor applications.
• Easy wiring termination featuring a secure screw terminal block on the flush-mount sensor module.

Specifications

• Temperature Measurement Range: 32.0°F to 104.0°F (0.0°C to 40.0°C).
• Sensor Element Type: Local 1k ohm Platinum Resistance Temperature Detector (RTD), Class A per IEC 60751.
• Temperature Accuracy: Plus or minus 1.0°F (plus or minus 0.6°C).
• Supply Voltage: 9.8 to 16.5 VDC (15 VDC nominal) supplied directly from the SA Bus.
• Current Consumption: 12 mA maximum under non-transmitting conditions.
• Communications Bus Rate: Auto-detects 9.6k, 19.2k, 38.4k, or 76.8k bps.
• Ambient Operating Conditions: 32°F to 104°F (0°C to 40°C); 10% to 90% RH, non-condensing.
• Dimensions: Fits typical 4-1/2 inch x 2-3/4 inch (114 mm x 70 mm) commercial configurations.
• Wire Size: Accommodates 18 to 22 AWG field-supplied wiring (22 AWG recommended).

Applications

• Commercial HVAC systems utilizing Metasys and Facility Explorer automation platforms.
• Office spaces, corporate buildings, and classrooms requiring accurate zone temperature monitoring without public control interfaces.
• Industrial or institutional buildings where clean-wall aesthetics are preferred and building staff manage environmental settings centrally.
• Multi-sensor zones where multiple network sensors must be addressed individually to feed environmental data into a single local controller.
