CI-12, CI-24 Occupancy Sensor for HVAC, BAS

User adjustable timedelay and sensitivity viaDIP switch

Low profile design

ASIC technology reducescomponents and enhancesreliability

Interfaces directly with EMSor HVAC system throughinternal isolated relay

• ASIC technology reduces components andenhances reliability

• Pulse Count Processing eliminates false offswithout reducing sensitivity

• Detection Signature Analysis eliminates false trig-gers; provides immunity to RFI and EMI

• Digital time delay adjustment from 30 seconds to30 minutes

Four-level Fresnel lensoffers superior desktopdetection

The Watt Stopper’s CI-12 and CI-24 ceiling mountpassive infrared occupancy sensors reduce energywaste in unoccupied building spaces by communi-cating occupancy to EMS and HVAC systems.

Coverage

Coverage for the sensors can reach up to 1200square feet using the Extended Range lens and 500square feet using the High Density lens (circularpattern) for walking motion. For typical desktoplevel activity, coverage can reach up to 300 squarefeet.

Applications

The CI-12 and CI-24 offer an easy way to reduceenergy consumption in a large variety of buildingspaces. By working directly with a BuildingAutomation System, the cost of purchasing powerpacks and the cost of labor for power pack installa-tion is eliminated. Furthermore, the sensors’ lowunit cost and reduction in energy consumptionresult in fast paybacks.

Operation

The CI-12 and CI-24 occupancy sensors integratewith building control systems via an internal isolatedrelay. The isolated relay has normally open and nor-mally closed outputs and is rated for 1 Amp at 24VAC/VDC. The CI-12 connects directly to 12 VDCbuilding control systems and the CI-24 connects to24 VAC or 24 VDC building control systems. Powerpack use is not necessary. When occupancy isdetected, the sensor signals a building controlsystem that then either turns devices on, such asheating or air conditioning, or increases their levels.Likewise, when the controlled area is vacated, thebuilding control system will reduce airflow and fanspeed or turn devices off.

DESCRIPTION

Special version daylight sensor designed specifically to work withLutron’s Digital microWATT Lighting Zone Controller to imple-ment daylight harvesting. This daylight sensor, in conjunctionwith the Digital microWATT Lighting Zone Controller, automati-cally dims lights when available daylight is high and brightenslights when daylight is low in order to maintain a specific lightlevel in the space.

This daylight sensor is calibrated for daylight sensitivity throughthe Digital microWATT Lighting Controller software, and mountsvery easily on any ceiling tile with one 2” hole.

of the window• Do not position Daylight Sensor in the well of a skylight or

above indirect lighting fixtures• Ensure that the view of the Daylight Sensor is not obstructed

Wiring the Daylight SensorMake sure that the supply breaker to theDigital microWATT® Lighting ZoneController is OFF.

Connect the three conductors to the threeMW-PS wires as shown.

Connect the three conductors to the corresponding terminals on the DigitalmicroWATT® Lighting Zone Controller.

Caution – Observe all localand national electrical codesand Safety Standards.

Note: Each Digital microWATT® LightingZone Controller must have it’s ownDaylight Sensor. Multiple Daylight Sensorscan not be used with a DigitalmicroWATT® Lighting Controller nor canmultiple Digital microWATT® LightingControllers share a Daylight Sensor.
