OVERVIEW
The nLight nCMR 9 2P Series Standard Range 360º occupancy sensor adds a second level
of independent control to the similar single pole version (nCMR 9). With two integrated line
switching relays, the nCMR 9 2P is designed for applications where locating power packs is
difficult or where extra relays are needed to signal auxiliary systems. By using Passive Infrared
(PIR) technology to provide maximum viewing from the ceiling, this sensor views up to 12 ft (8.53
m) in all directions when mounted at 9 ft (2.74 m). Its circular coverage pattern is 24 ft (17.07 m)
in diameter and is designed for detection of walking type motions.
Additionally, the nCMR 9 2P may be used in combination with other nLight sensors to
customize coverage for very large or irregularly shaped spaces. In applications where detection
of minor motion is required, use the nCMR PDT 9 2P Series Dual Technology occupancy sensor.

WIRING (DO NOT WIRE HOT)
Sensor does not power itself. Power is provided via the CAT-5 connection from either a power pack (nPP16) within its zone or a Bridge. Additionally, each
of the sensor’s integrated relays can function as a line voltage switching relay or as a dry auxiliary relay. Each pole’s hot and load wires are interchangeable.

MOUNTING
•Mount sensor using holes that align with a 3.5” octagon box or single
gang handy box (screws not provided)
•Connect Class 1 wires to line voltage feeds and loads
•Interconnect unit (via RJ-45 ports) with other nLight devices in lighting
zone (and/or Bridge) using CAT-5 cables
•Once power is received via CAT-5 connection, all devices in zone will
automatically begin functioning together according to each device’s
defaults
•Sensor will detect motions crossing segments more effectively than
motions parallel to beams
•For optimal detection, position sensor such that segments are crossed
upon entrance and unable to view outside the space
