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.
