THE SENSOR SWITCH ADVANTAGE IN DAYLIGHTING CONTROLSensor Switch, the industry leader in Occupancy Sensor Products & Technology, has engineered Photocel

Technology and Dimming Control to a higher level in a new line of Daylighting Control sensors that achieve maximum

energy savings at a fraction of the cost of competitive solutions.

PRACTICAL CONTROL SOLUTIONSOur daylighting control solutions are available in stand-alone sensors or incorporated into our occupancy sensor

products. This approach allows the unique requirements of every room and application to be lled by the mos

practical and cost effective solution.

Automatic On/Off Switching (-PC)

Automatic Dimming Control (-ADC)

Automatic Stepped Dimming (-DZ) Dual Zoned Control (-DZ)

ADVANCED SENSOR INTELLIGENCESeveral features make our sensors the most intelligent in the industry and have allowed us to improve upon traditiona

daylight harvesting methods.

Distinguishes between controlled light and ambient light

Sensor controls are fully integrated, removing the need for separate & expensive control units

Integrated foot candle measurement, each sensor literally is a foot candle meter

Automatically adapts to changes in room lighting conditions (lamp aging / burn out, furniture

alterations)

INSTALLER FRIENDLYBesides easing the stress on the pocket book, weve also eased the stress of the installer by simplifying the previously

complicated task of calibrating photocell products.

Automatic Set-Point Programming requires only one installation visit

Calibration can be done at any time of day & under any lighting conditions

Integrated 100 hour override timer simplies lamp burn-in

Push-button operation, no tools or analog adjustments required

A No daylight is available; the lights stay on as normal.

B Sufcient daylight is present to maintain the set-point without

any contribution from the lights; the lights are switched off.

This level is equal to the set-point plus the deadband.

C Daylight levels fall below the set-point; the lightsswitch back on.

A No daylight is available; the dimmable ballast operates

at full bright level (10 VDC).

B Increasing daylight begins to contribute to the overall

light level; the ballast is dimmed proportionally.

C Sufcient daylight is present to maintain the set-point; the

ballast is held at its full dim setting (0 VDC).

D Daylight levels drop into the dimming range (deadband); the

dim level of the ballast is reduced proportionally.

E Daylight levels fall below the set-point; the ballast is back to

full bright level (10 VDC).

A No daylight is available; the dimmable ballast operates at full

bright level (10 VDC).

B Increasing daylight begins to contribute to the overall

light level; the ballast is dimmed proportionally.C Sufcient daylight is present to maintain the set-point; the

lights are switched off.

D Daylight levels drop into the dimming range (deadband); the

lights are switched on with the ballast set at its full dim level.

E Daylight levels continue to drop; the dim level of the ballast is

reduced proportionally.

F Daylight levels fall below the set-point; the ballast is back to

full bright level (10 VDC).

SENSOR SWITCH SOLUTIONS

AutomaticOn/Off Switching (-PC)The most basic and low cost daylighting control solution, this method can

be implemented with standard ballasts.

Automatic Dimming Control (-ADC)Also called Continuous Dimming, this method controls 0-10 VDC dimmable

ballasts.

Sensor Switch Advantage: While other daylighting control solutions provide On/Off Switchingand Continuous Dimming in separate discrete products, Sensor Switch offers sensors that combine

these methods together for an even more effective solution.!

Photocell Defnition: A light-responding electronic component that

enables measurement of incident radiant energy (daylight

& articial light).

Sensor Switch Advantage:To ensure a more uniformresponse from the photocells used in our sensors

we utilize a sophisticated calibration procedure during

our manufacturing process.

Set-Point Defnition:The target light level that is to be maintained.

The function of a daylighting control sensor is to

measure the amount of daylight available, compare

it with the set-point, and then adjust the level of the

controlled lighting accordingly.

Sensor Switch Advantage:Since selection of the proper set-point is crucial to proper operation,we have enabled our sensors to automatically nd its optimum set-point.

Deadband Defnition: The light level contributed by the articial lights being controlled plus a safety range. Sensor Switch Advantage:Our sensors track the deadband in order to ensure that changes in

room lighting conditions (lamp aging / burn out, furniture alterations) are compensated for in the

sensors operation.

Closed Loop Operation Defnition: When the photocell in a sensor can view and provide feedback on the lights it controls.

Conversely, Open Loop operation occurs when the sensor does not have feedback on the

controlled lights.

Sensor Switch Advantage:Our daylighting control sensors can operate open or close loop.

INSTALLATION & CALIBRATION

Automatic Lamp Burn-in Integrated 100 hour override timer

LED blinks continuously to indicate burn-in mode engaged

Sensor runs automatic set-point programming when 100 hours has elapsed

Set-point Programming Automatic set-point programming enables the sensor to self-calibrate

Exact value selected (in foot candles) can be read out from the sensor via a series of LED ashes

Additional Manual and Incremental programming modes provide Override Control

DAYLIGHTING CONTROL BASICS

Beware of daylighting control solutions that require:

Calibration under suitable daylight conditions The room to be in move-in condition Two light level readings done during day & during night

Sensor Switch Advantage:To install a Sensor Switch DaylightIng Control Sensor simply engage theAutomatic Lamp Burn-in or Set-Point Programming mode and walk away!

Dual Zone ControlDaylight contribution diminishes as the distance from the

source (windows) increases. To address this fact, our

Dual Zone (-DZ) option provides control of a second zone

of lights via the Percentage Offset operational mode

This mode uses a relative set-point for the second zone

that is a user selected percentage higher than the primary

zones set-point. The sensor is installed in the rst zone

and runs in normal closed loop operation. The second

zone runs open loop. This operational mode is idea

for classroom applications with individually controlled

parallel rows of lights that are different distances from the

windows.

Stepped Dimming ControlProviding automatic daylighting control in rooms wired

for stepped dimming (also called Inboard/Outboardor A/B) is possible using our Duo operational mode

In this mode the sensor determines the necessary On/

Off combination of lights in order to maintain adequate

lighting. For example, in a dual switched three lamp

xture the sensor learns the light contribution provided

by each of the combinations. Then as daylight conditions

change, the necessary lamps will be switched On or Of

as needed to achieve desired lighting levels (set-point).

OPERATIONAL MODES

Inhibit Only OperationIn this mode occupancy sensors with daylight override can prevent the lights from turning on, however once they are needed

and turn on, the daylighting control functionality is disabled until the occupancy timer expires and turns the lights out.

Occupancy Sensors w/ Daylight OverrideIn these sensors, the presence of sufcient daylight can

override the lights ON state caused by occupancy (see

graph on right).

Sensor Switch Advantage: Occupancy sensorswith daylighting controls minimize cost and footprint

requirements while maximizing energy savings.
