The ADSM703H is designed to replace a standard single pole or multi-way switch or
dimmer. The dimmer uses passive infrared technology to sense human motion in a space
and turn the lights ON when occupancy is detected and OFF when the room is vacant. It is
ideal for applications in a home where there is a direct line of sight from the dimmer to the
room and where dimming control is desirable such as bedrooms or family/living rooms.

Upon detection of occupancy the dimmer will turn the light ON. Pressing and holding the top
of the dimming paddle will brighten the connected light. Pressing and holding the bottom of
the dimming paddle will dim the connected light. The light level LEDs indicate the brightness
of the connected light. See ‘Tap Input’ section for more details on dimmer operation. The
dimmer will keep the connected light on until no motion is detected for the selected time
delay. If the controlled load is turned off manually by pressing the on/off button (e.g. to keep
the lights off while watching a movie) the dimmer will keep the connected load off as long as
it is detecting motion. The dimmer will automatically switch back to automatic-on operation
when no motion is detected for 5 minutes. If motion is detected within 30 seconds after it
automatically turns OFF, the ADSM703H automatically turns the load back ON. The dimmer
will automatically turn the lights on to the last light level.

The dimmer is factory preset to function with automatic-on operation. It can be adjusted to
function in manual-on mode. See ‘Adjusting the operating mode’ section.

LED functionality
The dimmer has one locator LED on the ON/OFF button in addition to 7 light level LEDs.
When the connected light is off the locator LED will be on and the light level LEDs will be
off. When the connected light is on, the locator LED will be off and the light level LEDs will
be on indicating the brightness of the light.
Note: The LEDs will only function when the neutral wire is connected. When the neu-
tral wire is not connected the dimmer will function properly, but the locator LED and
light level LEDs will never be illuminated.
See Step 4 above for details on how to wire the dimmer.

Initial Power Up Supply
There is an initial warm-up and calibration period the first time power is applied to the
dimmer, after a power failure lasting more than 5 minutes and after the load is replaced.

DIMMER ADJUSTMENT & PROGRAMMING
Adjusting the time delay
The factory setting for the time delay dial is 15 minutes. To increase the amount of time
the load remains ON after the last motion detection, turn the dial clockwise (maximum = 30
minutes). To reduce the amount of time the load remains ON after the last motion detec-
tion, turn the dial counterclockwise (minimum = 5 minutes). The unit will enter test mode if
the trimpot is turned fully counter-clockwise. Stop just before turning the trimpot completely
counter-clockwise to avoid entering test mode. See Test Mode section for further details.

Adjusting the light level
Adjust the light level setting to prevent the dimmer from automatically turning on the lights
when there is enough ambient light present in the space. This feature’s default setting
is disabled so that even the brightest light will not prevent the dimmer from turning the
connected load on when it detects occupancy. Follow these steps to enable the light level:
• The light level must be set when the lights would normally be turned off because there is
enough ambient light
• Wait until the time of day when the space is bright enough with the ambient light and
does not need additional electric light
• Flip the dip switch labeled “light level” to the on position
• Any time the ambient light gets to the current level or brighter the dimmer will not turn the
lights on automatically
• To disable this feature, turn the “light level” dip switch to the off position
Adjusting the operating mode
The dimmer has two operating modes – automatic-on and manual-on. The dimmer’s
default setting is automatic-on and will turn the lights on automatically when occupancy is
detected. Lights will turn off automatically once motion is no longer detected and the time
delay expires. If manual-on operation is preferred, flip the dip switch labeled “On Mode” to
the on position. Now the lights will no longer automatically turn on. The on/off button must
be pressed in order to turn the lights on. Lights will turn off automatically once motion is no
longer detected and the time delay expires. To switch back to automatic-on operation, flip
the dip switch labeled “On Mode” to the off position.

Disabling the locator LED
The locator LED can be disabled by pressing and holding the on/off button for 10 seconds.
After 10 seconds the locator LED will flash to indicate that the locator LED has been

disabled. To enable the LED, press and hold the on/off button for 12 seconds. The locator
LED will flash at 10 seconds, continue to keep holding down the on/off button until the
locator LED flashes twice at 12 seconds indicating that the LED has been enabled.

Changing the dimming curve
The dimmer’s default setting is to control incandescent lamps. If the connected load is a
fluorescent lamp (e.g. CFL) the dimming curve must be changed so that the device will
function properly. To change the dimming curve:
• Press and hold the on/off button and bottom of the dimming paddle simultaneously for 10
seconds. The locator LED will flash indicating that the dimming curve has been set.
• To change the dimming curve back to its default setting of controlling incandescent loads
press and hold the on/off button and the top of the dimming paddle for 10 seconds. The
locator LED will flash indicating that the dimming curve has been set.

Test Mode
Activate test mode in order to test the detection coverage. If the neutral wire is connected, the
locator LED will blink indicating that the unit is in test mode. During test mode the controlled
load turns on for 5 seconds each time the dimmer detects occupancy. Follow these steps:
• Turn the time delay trimpot fully counter-clockwise.
• Move out of the coverage area or stand very still. The controlled load turns off after
5 seconds if no motion is detected.
• Move into the coverage area. The controlled load turns on for 5 seconds each time the
dimmer detects motion. After 5 seconds expires without motion detection, the load turns
OFF. The controlled load turns on automatically with the next motion detection and stays
on for 5 seconds.
• Repeat as necessary to ensure that the desired coverage area is within detection range.
• The device will remain in test mode for 5 minutes before automatically converting back to
normal operation. If additional time is needed, turn the trimpot away from the minimum
setting, and then turn back to its minimum setting, resetting the 5 minutes.
• Turn the trimpot back to the desired time delay once the coverage area has been verified.

TAP INPUT
On/Off button
• Momentary push with Load Off turns Load On to LDL (last dim level).
• Momentary push with Load On turns Load Off.
• Push and hold approximately 2 sec with Load On fades Load Off over approximately
30 sec (“go to bed” feature). During the slow fade-off interval the top-most lit LED in the
bargraph will flash.

• Momentary push with Load On increases brightness 1 increment (approx 5% of max
brightness).
• Push and hold with Load On ramps brightness up (approx 5 sec from min to max).
• Double-tap with Load Off turns Load On to maximum brightness.
Bottom of Dimming Paddle
• Momentary push with Load Off turns Load On to LDL (last dim level).
• Momentary push with Load On decreases brightness 1 increment (approx 5% of max
brightness).
• Push and hold with Load On ramps brightness down (approx 5 sec from
max to min).
• Double-tap with Load Off turns Load On to maximum brightness.

TROUBLESHOOTING
Status LED is enabled but the load will not turn ON:
• Check the lamp to make sure that it has not burned out.
• Check the circuit breaker to be sure it is functioning.

No status LED:
• Check the ground and neutral connections (note: neutral is not required for product to
function properly).

Load will not turn ON:
Press the ON/OFF button. The load should turn ON. If not:
• When power is applied, there is up to a 20-second delay before the device is operational.
Wait 20 seconds and try again to turn on the load.
• Check the light bulb and/or motor switch on the fan mechanism.
• Turn off power to the circuit then check wire connections.

Load will not turn OFF:
Make sure there is a solid ground connection. The device requires the ground connection to operate.
Note: The time delay can be set from 5 minutes to 30 minutes. Ensure that the time delay
is set to the desired delay and that there is no movement within the dimmer’s view for that
time period.
• To quickly test the unit for proper operation, turn the time delay to minimum and move out
of the dimmer’s view. Lights should turn off after 5 seconds.
• Press the ON/OFF button. If load does not turn off, turn off power to the
circuit then check wire connections.

Factory reset
To change the operating mode back to the default settings press and hold the on/off button
for 15 seconds. The locator LED will flash once at 10 seconds, continue to press and hold
the on/off button. The locator LED will flash twice at 12 seconds, continue to press and hold
the on/off button. The locator LED will flash 3 times at 15 seconds signaling that the device
has been reset.

Coverage Area
The ADSM703H has a maximum coverage
range of 180 degrees and a coverage area
of 600 sq. ft. The sensor must have a clear
and unobstructed view of the coverage area.
Objects blocking the sensor’s lens may prevent
detection thereby causing the light to turn off
even though someone is in the area. Windows,
glass doors, and other transparent barriers
will obstruct the sensor’s view and prevent
detection.

CAUTION Do not overturn the time delay adjustment dial.
