DESCRIPTION
Hubbell Adaptive Technology (AT series) ceiling mount occupancy sensors are designed to reduce installation time and prevent
callbacks resulting from improper sensor adjustment. Hubbell AT series sensors study their environment and automatically
adjust the time delay and sensitivity to optimize the sensor's performance for the specific application. Hubbell AT sensors must
be used in conjunction with a Hubbell control unit. The control units provide a 24VDC power supply for 1 to 3 sensors. The
correct control unit must be selected for the operating voltage of the application. Hubbell offers the following control units:
- CU300A(U)(M): 100-277V AC, 50/60 Hz.
- CU300HD:
100-277V AC, 50/60 Hz.
- CU347A:
347V AC, 60 Hz.
Each sensor is supplied with the hardware necessary for ceiling mounting.
FEATURES
• Adaptive Technology reduces installation time and prevents callbacks.
• Available in passive infrared (ATP/AHP series), ultrasonic (ATU series), dual technology - passive
infrared and ultrasonic (ATD series) models.
• Various models available for coverage areas from 500 to 2000 square feet.
• Isolated relay and photocell options provided on sensors with "RP" suffix.
• Visual motion indicators: ultrasonic-green LED, passive infrared-red LED.
• Sensor/ AAR* Capacity:
- CU300A(U)(M): 1 to 4 combined
- CU300HD:
1 to 6 combined
- CU347A:
1 to 3 combined
* Maximum of 2 AARs per control unit
PRE-INSTALLATION
1. NOTICE: For installation by a qualified electrician in accordance with national and local codes and
the following instructions.
2. NOTICE: For indoor use only.
3. CAUTION: RISK OF ELECTRIC SHOCK. Disconnect power before installing. Never wire
energized electrical components.
4. CAUTION: USE COPPER CONDUCTORS ONLY.
5. Check to see that the device's rating is suitable for the application.
6. When installing the Hubbell AT Series sensors, observe the maximum rated capacity of
the associated control unit:
- CU300A(U)(M): 15A Incandescent (1800W Tungsten) at 120V AC, 60 Hz.
20A Ballast (2400W Fluorescent) at 120V AC, 60 Hz.
20A Ballast (5540W Fluorescent) at 277V AC, 60 Hz.
- CU300HD:
20A, 120V AC Incandescent. 20A 120V AC or 277V AC Ballast.
Motor loads; 1 HP @ 120V AC, 2 HP @ 240/277V AC.
- CU347A:
15A Ballast (5205W) at 347V AC, 60 Hz.
7. NOTICE: Do not install if any damage to product is noted.
COVERAGE AND PLACEMENT
The patterns of coverage for the AT sensors are provided at right.
• Mounting ceiling height: 8 to 12 feet.
• The sensors must be mounted at least 4' from HVAC vents to avoid air current interference.
• For interior use only. These sensors should NOT be installed in damp locations such as near
a shower or steam source, in wet locations, or where exposed to rain unless PIR sensors
are used combined with ACIPE (NEMA 4X Enclosure) for outdoor and damp locations.
• Do NOT install in view of strong direct or reflected light sources.
INSTALLATION OF SENSORS
1. Disconnect Power.
2. Install CU series control units and, if applicable, AAR Add-A-Relay. See installation
instructions for these products.
3. Mount the sensor. The sensor must be mounted on the ceiling for proper operation. An
arrow is molded into the cover plate of the sensor. This should be used as a general
guideline to the direction of the coverage pattern. Fine tuning will be explained later.
Mounting options:
• For hard ceilings: Mount to a junction box.
• For false ceilings: Attach the cover plate by either using machine screws and punching a small
hole through the ceiling tile for the sensor wires (Figure A, below) OR using the threaded
mounting post then running the sensor wires through the center of the post, (Figure B, below).
4. Attach the sensor to the cover plate by aligning the keys in the cover plate with those in the
sensor housing. Rotate the sensor housing until proper orientation is achieved.
5. Using 3 conductor low voltage cable (18 to 22 AWG Type CL2, CL2P, CL2PR or CMR
as appropriate), connect the sensor and accessories to the control unit. Low voltage
wiring should not exceed 250 feet from the control unit to the last sensor. See control
unit installation instructions for wiring diagram.
6. Insulate all exposed leads with Listed/Certified electrical tape or twist-on connectors
(wire nuts).
7. Restore the power to the control unit.
8. Confirm the correct coverage by simulating motion in the coverage area which will be typical for
the application. If the desired coverage is not achieved, relocate the sensor to produce the desired
coverage. Test the sensor. To locate the test knob, remove the lens retainer and lens. Turn the black
timer knob fully counterclockwise from any clockwise position. Replace lens and retainer. The lights will
now turn off 8 seconds after motion stops. Reset timer for application. When installing sensors which
use passive infrared detection, the coverage pattern can be modified through the use of a lens mask.
