SAMSON OCEANFRONT PARK <br />CITY OF SUNNY ISLES <br />TECHNICAL SPECIFICATIONS <br />LIGHTING CONTROL DEVICES 16145 - 4 <br />F. Outdoor Sealed Units: Weathertight housing, resistant to high temperatures and equipped <br />with sun-glare shield and ice preventer. <br />2.5 <br />A. Ceiling-Mounting Units: Unit receives control power from a separately mounted auxiliary <br />power and control unit, and operates power switching contacts in that unit. <br />OCCUPANCY SENSORS <br />B. Ceiling-Mounting Units: Unit receives 24-V dc power from a remote source and, on sensing <br />occupancy, closes contacts that provide signal input to a remote microprocessor-based <br />lighting control system. <br />C. Switch-Box-Mounting Units: Unit receives power directly from switch leg of the 120- or <br />277-V ac circuit it controls and operates integral power switching contacts rated 800 W at <br />120-V ac, and 1000 W at 277-V ac, minimum. <br /> <br />D. Operation: Turns lights on when room or covered area is occupied and off when unoccu- <br />pied, unless otherwise indicated. <br />1. Time Delay for Turning Lights Off: Adjustable over a range from 1 to 15 minutes, <br /> minimum. <br />2. Manual Override Switch: Turns lights off manually regardless of elapsed time delay. <br />3. Ambient-Light-Level Control: Adjustable for setting a level of ambient illumination <br /> above which sensor will not turn lights on when occupancy is sensed. <br />4. Isolated Relay Contact: Operates on detection of occupancy or vacancy, as indicated, <br /> to activate an independent function. <br /> <br />E. Auxiliary Power and Control Units: As follows: <br />1. Relays rated for a minimum of 20-A normal ballast load or 13-A tungsten filament or <br /> high-inrush ballast load. <br />2. Sensor Power Supply: Rated to supply the number of connected sensors. <br />F. Passive-Infrared Type: Detects occupancy by a combination of heat and movement in zone <br />of coverage. Each sensor detects occupancy anywhere in an area of 1000 sq. ft. by detecting <br />occurrence of 6-inch minimum movement of any portion of a human body that presents a min- <br />imum target of 36 sq. in. to the sensor. <br />G. Ultrasonic Type: Emits a beam of ultrasonic energy and detects occupancy through use of <br />Doppler's principle in discerning movement in zone of coverage by sensing a change in <br />pattern of reflected ultrasonic energy. <br /> <br />H. Dual-Technology Type: Uses a combination of passive-infrared and ultrasonic detection <br />methods to distinguish between occupied and unoccupied conditions for area covered. <br />Particular technology or combination of technologies that controls each function (on or <br />off) is selectable in the field by operating controls on unit. <br /> <br />2.6 <br />A. Description: Electrically operated and mechanically held, and complying with UL 508 <br /> and NEMA ICS 2. <br />MULTIPOLE CONTACTORS AND RELAYS
