PHOTOCELL OPERATION
The nCM ADCX RJB sensor continuously adjusts
a space’s lighting to achieve maximum daylight
harvesting while maintaining a minimum
light level referred to as the set-point. When
no daylight is available, the sensor allows the
controlled dimmable lighting to operate at
its full bright level. As daylight increases and
begins to contribute to the overall light level of
the room, the Automatic Dimming Control (ADC)
feature starts dimming the room proportionally,
eventually reaching the full dim level (or
optionally switching o, see paragraph below).
As the daylight levels fall, the ADC feature will
again take control of the lights; reducing the
dim level (increasing the brightness) in order to
achieve the necessary total light level. At the point when all daylight contribution is gone, lighting will be
back at its full bright level.
The nCM PC RJB sensor does not control
dimming, but instead signals nLight devices
located elsewhere within the sensor’s zone to
switch a controlled lighting load on when more
light is needed. The lights are also signaled to
turn o when light is above the set-point plus
a 10% safety factor and deadband. The safety
factor will prevent the system from cycling
when the light level is very near the set-point.
The deadband is the level of light contributed by
the articial lights being controlled. This level
is tracked so if the lighting conditions change
(for example a lamp burns out) the point at
which the lights turn o is adapted accordingly.
If the photocell can not view the lights being
controlled (for example if it is looking up at skylights), there is no deadband and the sensor is said to be
working open loop. There is also an adaptive cloud delay (optional) before the photocell turns the lights o
to prevent the system from cycling on a cloudy day.
PRODUCT OVERVIEW
The nCM ADCX RJB and nCM PC RJB photocell sensors are ceiling/surface mount devices that provide
a range of daylight harvesting features for nLight Control System installations with nished ceilings (e.g.
ceiling tiles, sheetrock, plaster). The nCM PC RJB version provides on/o photocell control by default,
while the nCM ADCX RJB provides automatic dimming photocell control by default. Ideal for spaces
with windows, such as vestibules, corridors, classrooms, or oces, these sensors work by rst monitoring
daylight conditions in a room. They then signal networked nLight control devices to adjust their dimming
outputs (and/or turn lighting o) to obtain maximum energy savings while ensuring adequate lighting
levels are maintained.
The nCM ADCX RJB sensor controls nLight enabled luminaires (e.g. VTLED Family from Lithonia), nLight
dimming relay packs (e.g. nPP16 D or nSP5 PCD), or auxiliary dimming output devices (e.g. nIO D).
The nCM PC RJB switches nLight enabled luminaires or any relay/dimming device in an nLight system
(e.g. nPP16). Both sensors can also be used together with nLight occupancy sensors. Manual override or
adjustment of the dimming level is possible viaWallPod dimmers or through the SensorView software.
Both versions are powered via the nLight network bus and can communicate with one or more nLight
enabled luminaires or nLight relay/dimming packs to enable control of xtures individually or in groups.
These congurations work standalone and do not require a connection to a larger nLight network.

nLIGHT NETWORKED OPERATION
nCM ADCX RJB and nCM PC RJB sensors are native nLight devices meaning they are individually
addressable and digitally communicate to other nLight devices such as WallPod switches, power
packs, nLight-enabled digital luminaires, and other sensors. All devices are wired using CAT-5e
cabling; creating a local nLight control zone. Once linked to an nLight Gateway, either directly or via
an nLight network backbone, the zone becomes capable of remote status monitoring, conguration,
and control with nLight SensorView software.

www.acuitybrands.com/CustomerResources/Terms_and_conditions.aspx
Note: Specications subject to change without notice. Actual performance may dier as a result of end-user environment and application.
The following instructions are for mounting sensor directly to a ceiling tile or
sheetrock surface. Sensor’s mounting holes also align with standard round xture or
single gang handy box (screws not provided).
1. Using template included with unit, mark spots on ceiling tile/sheetrock for cable
hole and mounting anchors/screws
2. Drill 1/2”hole through ceiling surface at location indicated on template
3. Insert provided anchors into ceiling surface at locations indicated on template
4. Remove provided RJ-45 splitter from sensor’s attached CAT5e cable and
thread cable (and low voltage wires if -AR option included) through hole from
underside
5. Mount sensor to anchors using two screws provided
6. Reattach RJ45 splitter device (model CAT5 Y) above ceiling to cable from sensor
