1. Introduction
This manual provides comprehensive instructions for the installation, operation, and maintenance of the Sensor Switch RES7Z nLight-Air Fixture Embedded Wireless Occupancy DayLighting Sensor. The RES7Z is a low-voltage, digital sensor designed for integration into indoor luminaires, offering advanced wireless lighting control, digital dimming, occupancy detection, and daylight harvesting capabilities.
It is suitable for mounting heights up to 20 feet and provides Passive Infrared (PIR) occupancy detection with a 15-20 ft radial coverage pattern, along with photocell light level detection. Optional Dual Technology adds Microphonics to PIR detection for enhanced accuracy.
2. Safety Information
- Always disconnect power before installing or servicing the device.
- Installation should be performed by a qualified electrician in accordance with all national and local electrical codes.
- Do not exceed the specified voltage and current ratings. The device operates on 5-42 VDC input power.
- Ensure proper grounding to prevent electrical shock.
- This device is designed for indoor use only.
3. Product Overview and Features
The RES7Z sensor integrates multiple functionalities into a compact, low-profile design:
- Fixture Embedded Design: Specifically engineered for seamless integration within lighting fixtures.
- Wireless Control: Utilizes nLight AIR technology for wireless communication and control.
- Occupancy Detection: Passive Infrared (PIR) sensor detects human presence, with optional Microphonics for enhanced detection.
- Daylight Harvesting: Integrated photocell measures ambient light levels to optimize artificial lighting.
- Digital Dimming: Enables precise control over light output.
- Wide Voltage Input: Operates with 5-42 VDC input power.
- 360-Degree Lens: Provides comprehensive coverage for occupancy detection.
- Generation 1 Compatible: Ensures compatibility with existing nLight Generation 1 systems.

4. Setup and Installation
The RES7Z sensor is designed for in-fixture installation. A programmable output channel is required for its operation. Ensure the power source (sold separately) provides 5-42 VDC.
4.1 Wiring Connections
Refer to the product label for specific wiring details. The sensor typically uses a low-voltage connection. The label indicates connections for LEDCODE2 (BRN, YEL) and LED output 2 (BLK, RED).

4.2 Mounting
The sensor is designed to be embedded within a luminaire. Ensure the sensor's lens has an unobstructed view of the area to be monitored for optimal occupancy detection and daylight harvesting.

4.3 Configuration
The RES7Z sensor requires a programmable output channel for configuration. Refer to the nLight AIR system documentation for detailed instructions on programming occupancy settings, daylight harvesting thresholds, and dimming levels.
5. Operation
Once properly installed and configured within the nLight AIR system, the RES7Z sensor operates automatically:
- Occupancy Detection: The sensor detects motion within its 15-20 ft radial coverage area. Upon detection, it signals the connected lighting fixture to turn on or adjust to a pre-programmed level. If no motion is detected for a set period, the lights will dim or turn off.
- Daylight Harvesting: The integrated photocell continuously monitors ambient light. When sufficient natural light is available, the sensor will automatically dim or turn off artificial lighting to maintain a desired light level, saving energy.
- Wireless Communication: The sensor communicates wirelessly with other nLight AIR devices, allowing for flexible and scalable lighting control solutions.
6. Maintenance
The RES7Z sensor is designed for minimal maintenance. Follow these guidelines:
- Cleaning: Periodically clean the sensor lens with a soft, dry cloth to ensure optimal performance. Avoid abrasive cleaners or solvents.
- Inspection: Regularly inspect the sensor for any physical damage or loose connections.
- Firmware Updates: Check the Sensor Switch or Acuity Brands website for any available firmware updates for the nLight AIR system, which may include improvements for the RES7Z sensor.
