Complete Compiled Specification.pdf - Peck Ormsby Construction

F. Shall have a standard 30 element Fresnel lens with 15 layers horizontally and 4 layers
vertically, a 14 element Long Range Fresnel lens with 9 layers horizontally and 4 layers
vertically, or an Aisle Way Fresnel lens with 14 layers horizontally and 9 layers vertically.
G. Shall cover up to 1200 square feet with the Standard Lens, up to 90 linear feet with the Long
Range Lens, and up to 120 linear feet with the Aisle Way Lens for walking motion when
mounted at a ceiling height of 12 feet.
H. Shall operate on 24 VDC, current draw of 19 Ma.
I. Watt Stopper Model CX-100
2.5 CEILING MOUNT ULTRASONIC TYPE (For Restrooms, Open Office Areas up to 1000 square
feet)
A. Shall be omni-directional with volumetric coverage of 360 degrees and up to 1000 square
feet of walking motion.
B. Shall have a multi-direction transmitter with temperature and humidity resistant, minimum 32
kHz tuned ultrasonic receivers. Ultrasonic receivers shall be temperature and humidity
resistant with less than a 6dB shift in the humidify range of 10% to 90% and less than a 10dB
shift in the temperature range of -20 to 60 degrees C.
C. Sensors of varying frequencies shall not be allowed so as to prevent sensors from interfering
with each other and to ensure compatibility in the event more sensors are added or units are
replaced.
D. Shall be furnished with a convenient shunt provision which will enable a by-pass in the event
of failure. This by-pass provision pin shall remain in the sensor and be visible from the floor
as a constant reminder that the automatic function has been by-passed.
E. Shall have user-adjustable sensitivity setting and time delay setting from 15 seconds to 15
minutes.
F. Shall operate on 24 VDC, current draw of 15 mA.
G. Watt Stopper Model W-1000A
2.6 CEILING MOUNT DUAL-TECHNOLOGY TYPE (For Rooms up to 1200 SF)
Low Profile, ceiling mount, 360 degree coverage: Watt Stopper Model DT-300
Adjustable arm, wall mount, 180 degree coverage: WattStopper Model DT-200
A. The Occupancy Sensors shall be capable of detecting presence in the floor area to be
controlled, by detecting doppler shifts in transmitted ultrasound and passive infrared heat
changes (dual technology). Sensors that utilize microphonics are not approved.
B. Upon entering a space, motion from both technologies must be sensed before lighting will be
turned on. After this has occurred, detection in either technology will hold lighting on for the
set time period. Sensors will have a retrigger time delay where only one motion is necessary
to turn on the lights within 5 seconds after turning off.
C. Ultrasonic sensors will be volumetric in coverage. Up to 10 different passive infrared patterns
will be available by lens selection. Detection shall be maintained when a person of average
