UNIT DESCRIPTION AND OPERATION
The WI-300 automatic wall switch sensor turns lighting systems on or off
based on occupancy and light levels. It is designed to replace the standard
wall switch and can control two independent lighting loads.
The WI-300 uses passive infrared technology to detect human motion in a
space. The sensor must have a clear view of the people in the space in order
to detect occupancy.
The WI-300 contains two relays. Dual switches, located on the front of the WI-
300, allow the user to control one or two lighting loads. Pressing an Auto/Off
switch from off to auto will turn the corresponding lights on. If no motion is pres-
ent for a time delay of 30 seconds to 30 minutes, lights will turn off.
The WI-300 also contains a built-in light level sensor that only affects the sec-
ondary relay. If adequate daylight is present, the sensor will hold secondary
lights off until natural light levels drop. Users can override this function by
placing their hand in front of the sensor. The lights will then remain on until
the space is unoccupied.
NOTE: If the Auto/Off switch is pressed while the lights are on, the lights
will turn off and not come back on until the Auto/Off switch is
pressed again.
.
COVERAGE PATTERNS
The WI-300 will cover up to 1000 sq. ft. and over 40 ft. from the sensor. The
Fresnel lens in the sensor has multiple-cell viewing lenses in four tiers. Its field
of view is180°.

Opaque adhesive tape is supplied
with the WI-300 so that sections of
the coverage area can be masked.
Since masking removes bands of
coverage, remember to take this
into account when troubleshooting
coverage.

1.Make sure that the power has been turned off at the circuit breaker.
2.Connect the wires of the WI-300 as follows:
BLACK (Line of Primary load), BLUE (Load of Primary load), RED
(Line of Secondary load), RED (Load of Secondary load) GREEN
(Ground)
Note: Ground must be connected for the switch to operate.
3.Attach the sensor to the wall by sliding the bottom screw through the key-
hole in the back of the unit and sliding the sensor down.
4.Insert the top screw into position and tighten.
5.Turn circuit breaker on. After 60 seconds, push the AUTO/OFF button and
the lights will turn on. This delay is due to initial power-up of the sensor and
only occurs during installation.

1.Remove the cover-housing
around the Auto/Off button. Press
button (Auto position) to turn
lights on and test unit operation.
(There is a 60 second initial
warm-up period prior to the lights
turning on.) Turn time delay to
minimum (counter-clockwise),
leave the room, and the lights
should turn off after 30 seconds.
2.To test sensitivity, make no
motion for 10 seconds. With
approximately one foot separat-
ing you and the sensor, move in
a sideways motion in front of the
sensor. The LED will blink when
movement is detected. Typically,
the sensitivity should be set at
maximum (clockwise).
3.The light level setting must be
made at a time when the lights
would normally be off due to adequate natural or external light. (If this fea-
ture is not needed, leave the light level adjustment at maximum (clock-
wise)). Note that the light level setting only affects the secondary relay.
• Adjust the light level setting to minimum and let the sensor time out so
lights are off. Enter the space and lights should remain off. Make sure your
body does not cast a shadow on the sensor, and adjust the light level trim-
pot dial clockwise in small increments. After each adjustment, wait 5-10
seconds to see if the lights turn on. Continue this procedure until the lights
turn on. From this setting the lights will not turn on if light levels are above
the current natural illumination.
4.Reset the time delay to the desired setting. The time delay can be set from
30 seconds to 30 minutes. Replace the front cover.

TROUBLESHOOTING
Lights will not turn on, LED does not flash:
1.Check the sensitivity settings. Make sure it is set to maximum (middle trim-
pot dial).
2.Check all wire connections and verify that the ground wire is tightly
secured.
3.If lights still do not go on, call (800) 879-8585 for technical support.
Lights will not turn off:
1.If time delay is adjusted to maximum, the lights will remain on for 30 min-
utes after last motion is detected.
2.To test if unit is operating properly, set time delay to minimum and move
out of the sensor’s view. Lights should turn off after 30 seconds.
3.If lights still do not go off, call (800) 879-8585 for technical support.
Sensing motion outside detection areas:
1.Opaque adhesive tape is included with the sensor and can be used to limit
the detection areas.
2.Adjust sensitivity to minimum to reduce excessive sensitivity.
Override function:
In the event of unit failure or if it is necessary to leave the lights on,
remove the “override jumper.” This will turn the AUTO/OFF button into a stan-
dard ON/OFF toggle switch.
Secondary Relay will not turn-on:
1. Check light level. Adequate daylight may hold off lights.
