Integrated Sensor with Individual Control
The MSD7ADCX PIR occupancy sensor/automatic dimming photocell is ideal for areas without
obstructions and where daylight harvesting may be desired. Suggested applications include, but
not limited to, hallways, corridors, storage rooms, and breakrooms or other areas where people
are typically moving.
The MSDPDT7ADCX PIR/Microphonics Dual Tech occupancy sensor/automatic dimming photocell is
ideal for areas with obstructions and where daylight harvesting is desired. Suggested applications
include, but not limited to, open offices, private offices, classrooms, public restrooms, and
conference rooms.

9 FT Mounting
• Recommended for walking motion detection from mounting heights between 8 ft (2.44 m)
and 20 ft (6.10 m)
• Initial detection of walking motion along sensor axes at distances of 2x the mounting
height up to 15 ft (4.57 m) and
• 1.75x up to 20 ft (6.10 m).
• Provides 12 ft (3.66 m) radial detection of small motion when mounted at 9 ft (2.74 m)
• Initial detection will occur earlier when walking across sensor's field of view than when
walking directly at sensor

nLight AIR Wireless
nLight AIR is the ideal solution for retrofit or new construction spaces where adding additional
wiring can be labor intensive and nLight AIR is available with or without an integral sensor. The
integrated rES7 or rES7PDT smart sensors are part of each luminaire in the nLight AIR network,
which can be grouped to control multiple luminaires. The granularity of control with the digital
PIR occupancy detection and daylight sensing makes a great solution for any application.
nLight Wired Networking
The nES 7 is ideal for small rooms without obstructions or areas with primarily walking motion.
Ideal areas include hallways, corridors, storage rooms, and breakrooms. Additionally, the
nES7ADCX includes an integrated photocell, which enables daylight harvesting controls.
For areas like restrooms, private offices, open offices, conference rooms or any space with
obstructions, the nES PDT 7 dual technology sensor is recommended. The nES PDT 7 utilizes both
PIR (passive infrared) and Microphonics technologies to detect occupancy. Additionally, the
nESPDT7ADCX includes an integrated photocell, which enables daylight harvesting controls which
is ideal for areas where windows are present.
