The NCM xx RJB family of nLight ceiling/surface mount occupancy sensors provide a range of networked sensor solutions for applications with finished ceilings (e.g. ceiling tiles, sheetrock, plaster).

• NCM xx RJB family sensors utilize 100% digital Passive Infrared (PIR) detection and are available with several lens options, providing flexibility for multiple mounting height and coverage pattern requirements.
• Dual technology occupancy detection can also be added as an option for applications where occupants are stationary for long periods of time.
• NCM xx RJB family sensors are also available with an optional auxiliary low voltage relay for simple integration with a BMS system or other building system.
• NCM xx RJB family sensors are powered via the nLight network bus and typically communicate with one or more nLight enabled luminaires (e.g. Lithonia VTLED Series) or nLight relay/dimming packs to enable control of fixtures individually or in groups. These configurations work standalone and do not require a connection to a larger nLight network.
• 100% digital PIR detection
• Optional dimming photocell (ADCX option)
• Optional auxiliary low voltage relay (AR option) for dry contact output – relay only tracks occupancy by default, ignoring switch and photocell commands
• LED status indicator
• Adjustable settings (e.g. occupancy time delays, photocell set-points) via push-button or SensorView software application
• Broadcasts occupancy and photocell information over a local nLight channel
• Remotely upgradeable firmware
