Installation Instructions
DESCRIPTION AND OPERATION
The FM-105 microwave occupancy sensor uses ultra-high-
frequency radio waves, also known as “microwaves” and
the principle of the Doppler Effect to detect motion. The
sensor sends out radio waves that bounce off of nearby
surfaces and return to the sensor. Motion in the area
changes the speed of the waves returning to the sensor. The
sensor detects the change and interprets it as occupancy.
This causes the sensor to turn ON the load.
Microwaves can penetrate certain materials, therefore,
the FM-105 can be installed behind a luminaries’ plastic or
glass lens.
The FM-105 can be used in a water-tight non-metallic box
or water-tight luminaire for wet location applications.
Daylighting Control
The FM-105 also has daylighting control capability. The
daylight control on the FM-105 is a “HOLD-OFF” type. The
sensor stops the load from turning ON if the ambient light
is greater than the daylighting setpoint. If the load is already
ON, the sensor will not turn OFF the load due to high
ambient daylight.

INSTALLATION
CAUTION
TURN THE POWER OFF AT THE
CIRCUIT BREAKER BEFORE
INSTALLING THE SENSOR.
1. Determine the mounting location inside the luminaire
or other suitable enclosure. If the daylight feature will
be used, be sure to locate the sensor where daylight is
not completely obscured from the sensor.
2. Attach the metal shield to the FM-105 so that the
shield is located between the FM-105 and the lamp.
Make sure that the wiring terminals on the FM-105 are
accessible.
3. Put the plastic mounting foot onto the base of the
FM-105 to secure the metal shield in place.
4. Secure the FM-105 assembly in place using screws
through the plastic mounting foot.
5. Connect the line voltage and load wires to the FM-105
terminals as shown in the wiring diagram.
• Do not allow bare wire to show.
• Make sure all connections are secure.
6. Restore power from the circuit breaker.

Mounting foot: Align 4 corner studs on the bottom of the
FM-105 with 4 corner slots on mounting foot. Twist to secure.
ADJUSTMENTS
Three trimpots on the FM-105 allow you to
adjust the time delay, sensitivity/range, and
light level setpoint. To reduce a setting, turn
the associated trimpot counter-clockwise
toward the minimum setting. To increase a
setting, turn the trimpot clockwise toward
the maximum setting.
Warning: Do not overturn the adjustment trimpots!
Time Delay
The FM-105 automatically turns OFF the load after the coverage
area has been vacant for the amount of time set in the time delay.
The minimum setting is 10 seconds, maximum is 30 minutes.
Call 800.879.8585 for Technical Support • www.wattstopper.com
Range/Sensitivity
It is possible for a microwave sensor to “see” through solid
objects and detect motion if the sensitivity is set too high. If you
are getting detections and the load will not turn OFF, reduce the
sensitivity slightly and see if that corrects the situation.
Light Level
Adjust the daylighting setpoint when ambient light is sufficient
to keep the lights OFF. Set the time delay to minimum. Adjust
the light level trimpot in small increments. Wait 1 to 2 minutes
between adjustments. After the time delay expires and the load
turns OFF, move within the detection area of the sensor. If the
load comes back ON, you need to repeat the procedure.
IMPORTANT STARTUP INFORMATION
The first time the sensor is powered-up the load will flash ON
then OFF once, then there will be 10 seconds while the sensor
warms-up. After that time the sensor will work normally.
TROUBLESHOOTING
To quickly test the unit, turn the time delay to minimum. Move
out of the sensor’s view. Lights should turn OFF after 10 seconds.
Move into the sensor’s view. The lights should turn ON.
Lights do not turn ON:
1. Cover the sensor to simulate darkness then move in the
coverage area. If the load turns ON, adjust the light level.
2. Check all wire connections. Verify all wires are secure.
Lights do not turn OFF:
1. If there is no motion in the desired coverage area, the
sensor may be picking up movement on the other side of
a wall, partition, window or door. Reduce the sensitivity.
2. Verify time delay and that there is no movement
within the sensor’s view for that time period.
