5. Put the CD-250s (and RH-253s if applicable) into their respective wall boxes.
Position them with the lens positioned above the ON/OFF/DIM button (lens at
top, ON/OFF/DIM button at bottom). Secure to the wall box with the screws
provided.
6. Make any necessary adjustments.
See the SENSOR ADJUSTMENT section for information.
7. Install cover plate.
Install industry standard decorator wall switch cover plate (not included).
8. Restore power to the circuit.
Turn on the breaker or replace the fuse.
INITIAL POWER-UP DELAY & CALIBRATION
There is an initial one minute warm-up and calibration period the fi rst time
power is applied to the unit, after a power failure lasting more than 5 minutes
and after the dimming load is replaced.
Load Calibration: The CD-250 calibrates its dimming range to the load’s wattage
rating by briefl y dimming the load up and down from its minimum output
(approx. 10%) to its maximum.
SENSOR ADJUSTMENT
To adjust the CD-250, you use a control located under the ON/OFF/DIM button.
The wall switch cover plate must be
removed to gain access to the time
adjustment dial under the ON/OFF/DIM
button.
For multi-way operation, the Time
Delay should be the same in all
sensors related to the same load.
1. Firmly grasp the side edges of the
Lock Bar and gently pull it away from
the switch face until it clicks. Do NOT
attempt to pull the Lock Bar off of the
switch!
2. Firmly grasp the side edges of the
ON/OFF/DIM button. Slide the button
downward approximately 1/2 inch to
expose the adjustment dials.
Adjusting the Time Delay
Turn the right dial counter-clockwise to
reduce the amount of time the lights will
remain on after the last motion detection (minimum = 15 seconds). Turn the
same dial clockwise to increase this time delay (maximum = 30 minutes). You can
only select the following values: 15 seconds/5 minutes/15 minutes/30 minutes.
Warning: Do not overturn the Time Delay adjustment dial!
TEST MODE
To test the detection coverage:
1. Press and hold the ON/OFF/DIM button. After 10 seconds the lighted switch
turns off. The load turns ON if it was not already ON. The sensor is now in
a TEST mode that lasts 5 minutes. (You can end the TEST mode sooner by
pressing the ON/OFF/DIM button for another 10 seconds).
During the TEST mode, the controlled load turns ON for 5 seconds each
time the sensor that initiated the TEST mode detects occupancy.
2. Move out of the coverage area or stand very still. The controlled load turns
OFF after 5 seconds if no motion is detected.
3. Move into the coverage area for the unit that initiated the TEST mode. The
controlled load turns ON for 5 seconds each time the sensor detects motion.
After 5 seconds expire without motion detection, the load turns OFF. The
controlled load turns ON automatically with the next motion detection and
stays ON for 5 seconds.
4. Repeat as necessary to ensure that the desired coverage areas are within
detection range.
You can do this test for each CD-250 in your multi-way confi guration. So
that you can determine the actual coverage area for each multi-way switch
individually, only the CD-250 that is in TEST mode will control the load.
