MOTION SENSOR
Models MLGS180B
MLGS180W
Features
• Turns on lighting when motion is detected.
• Automatically turns lighting off.
• Photocell keeps the lighting off during daylight
hours.
• LED indicates motion was sensed (day or night).
Requirements
• The Light Control requires 120-volts AC.
• If you want to use Manual Mode, the control must
be wired through a switch.
• Some codes require installation by a quali-
fied electrician.
OPERATION

Test 5 Sec x x
Auto 1, 5, 10 min. x
Manual Until Dawn* x
* resets to Auto Mode at dawn.
Note: When first turned on wait about 1 1/2 minutes
for the circuitry to calibrate.
TEST
Put the ON-TIME switch on the
bottom of the sensor in the TEST
position.
AUTO
Put the ON-TIME switch in the 1,
5, or 10 minute position.
MANUAL MODE
Manual mode only works at night
because daylight returns the sensor to AUTO.
Flip the light switch off for one
second then back on to toggle
between AUTO and MANUAL
MODE.
Manual mode works only with the
ON-TIME switch in the 1, 5, or 10
position.

INSTALLATION
For under eave installation, the sensor head
must be rotated as shown in the next two steps for
proper operation and to avoid the risk of electrical
shock.
For eave mount only:
❒ Swing the sensor head towards the clamp
screw.

Controls
❒ After screwing the sensor into the wall plate,
connect the junction box wires to the Light
Control wires by twisting together and securing
with wire connectors.

If the sensor pops out of the ball joint, loosen the
clamp screw and push the sensor back into the
ball joint. Tighten the clamp screw when done.
These instructions show the sensor wired to floodlamps. The white sensor wire is neutral. The
black sensor wire is hot. The red wire is the
switched "hot" wire. The lighting load (Up to 500
Watts, 4.2A Maximum) is placed across the white
and red wires.
WIRE THE LIGHT CONTROL.
❒ Turn power off at the fuse or circuit breaker.
❒ Remove the existing light fixture, if present.
Black to Black
Optional: Connect additional load across
the white and red wires. Total lighting
load including lampheads on fixture must
not exceed 500 Watts (4.2A).
MOUNT THE LIGHT.
❒ Follow the instructions that came with your light
fixture for mounting and adjusting the light fixture.
❒ Keep regular PAR-38 lamps at least 1" (25 mm)
from the sensor. Halogen lamps should be kept
at least 2" (51 mm) from the sensor.

TEST AND ADJUSTMENT
❒ Turn on the circuit breaker and light switch.
NOTE: Sensor has a 1 1/2 minute calibration
period before it will detect motion. When
first turned on, wait 1 1/2 minutes.
❒ Turn the RANGE control to the mid position and
the ON-TIME control to the TEST position.

Avoid aiming the control at:
• Objects that change temperature rapidly, such
as heating vents and air conditioners. These
heat sources could cause false triggering.
• Areas where pets or traffic may trigger the control.
• Nearby large, light-colored objects reflecting
light may trigger the shut-off feature. Do not point
other lights at the sensor.
