MPC-52V
360° Passive Infrared Line Voltage
Occupancy Sensor
SPECIFICATIONS
The MPC-52V 360° occupancy sensor uses advanced PIR technology to turn on
the lights when motion is detected and keep the lights on when movement is
present. The sensor will automatically turn off the lights if no movement is
detected within the amount of time selected in the time delay.
Refer to the wire diagram of the sensor (See Figure 4)
1. Connect the HOT wire to the BLACK wire on the sensor.
2. Connect the NEUTRAL wire to the WHITE wire on the sensor.
3. Connect the LOAD wire to the RED wire on the sensor.

The MPC-52V provides a 360° coverage pattern. The coverage shown represents
walking motion at a mounting height of 8 feet. For building spaces with lower levels
of activity or with obstacles and barriers, coverage size may decrease.

PIR Radius of 22'
(or 44' Diameter)
Location: Device should be mounted in a location free of obstruction from
furniture, plants, walls and vibration (see Figure 1). The sensor must be
mounted a minimum of 4 ft. away from any air vents. Avoid mounting the
sensor close to heat source. When mounting directly to a ceiling light fixture,
the lens of the sensor must be below the lowest point of the fixture.
MPC-52V is designed for a ceiling height of about 8-10 feet. Because of the
umbrella shaped coverage pattern, mounting above or below the
recommended height could reduce coverage range and sensitivity. It is not
necessary to have occupancy sensor coverage on every square inch of space
in any particular room.
The best location to install multiple MPC-52V is usually in the walkways of an
open office space (see Figure 2).
Figure 1 Figure 2
Helpful hints:
a. Make sure that the sensor's view of the entrance will not be blocked by
the door when it is open.
b. Program a longer time out to avoid the lights constantly turning on/off.
c. Do not mount sensors close to air vents.
d. Cover the main walkways.
e. Try to avoid having the sensor looking out the door of the space
Open Office or Classroom Area Coverage:
a.
b.
To get complete coverage in an open office area, install multiple sensors
so that there is at least 15% overlap with each adjacent sensor's
coverage area.
The sensors should cover the primary occupant's desk, the entrance and
any other areas with heavy traffic.
WARNING
Turn the POWER OFF at the circuit breaker
before installing the sensor
Read and understand these instructions before installing. This device is
intended for installation in accordance with the National Electric Code and
local regulations. It is recommended that a qualified electrician performs this
installation. Make sure to turn off the circuit breaker or fuse(s) and make sure
power is off before wiring the device.
Use copper wires only.

1. Cut a 7/8” round hole in the ceiling tile at the mounting location.
2. Attach the connector on the mounting base through the cutout.
3. Twist the locknut onto the connector
until the mounting base is tight.
4. Pull the high voltage wires through the connector.
5. Follow the wiring diagram and connect the high voltage wires to the
appropriate terminals on the sensor.
6. Attach the sensor and lock it onto the mounting base with a slight twist.

The MPC-52V has 4 DIP switches under the lens cover. They are used to
set the sensitivity and time delay. This device is factory preset for quick
installation and is ready to test once installed. After testing, adjust the DIP
switches and Light dial to desired levels.

50% -This setting will decrease the amount of area the sensor will cover to
half the range.
100% -This setting will allow the sensor to utilize the maximum range.
Maximum range of MPC-52V coverage is 800 square feet.
Time delay: DIP switch 2,3,4
The time delay is set with Dip switches 2, 3 and 4, from 15 seconds to
30 minutes. When there is no movement detected by sensor, the lights will
automatically turn off after the selected time delay has expired.
LED does not blink:
1. Make sure the sensor has power.
2. Check the location of the sensor and verify that the sensor
can detect motion from human body. If not , the LED will
not blink.
3. Check the wire connections and verify that the wires are
secured with wire caps.
4. Make sure the HOT and NEUTRAL wires are not reversed.
LED blinks but lights do not turn ON:
1. Check the “Light” setting. If the arrow is pointed to the
“-“position, the area needs to be dark enough for the sensor to
operate. Cover the light sensor lens to simulate darkness. If the
light turns ON, the light level setting needs to be adjusted.
2. Make sure the wires are connected and bulbs are working.
3. Check for obstructions in the lens cover.
4. Make sure that power to the sensor has been ON continuously for
at least one minute. Wait for the warm-up period to end.
Lights do not turn OFF automatically:
1. If there is no motion from people or equipment in the sensor’s view but
the LED blinks, look for any nearby source of infrared energy (heat) in
motion, such as turbulent air from a heating or cooling supply.
•Mount the sensor so that it’s lens is below the edge of the fixture
and does not directly view the lamps.
•Move the air supply away from the sensor, or move the sensor.
2. Verify the time delay settings in switches 2-4. The time delay can be set
from 15 seconds to 30 minutes. Ensure that the time delay is set to the
desired delay and that there is no movement within the sensor’s view for
that time period.
3. Check sensor wire connections, verify load and neutral wires are
secure.
TESTING OCCUPANCY SENSOR
Note: There is a 60- second warm-up period when power is first applied. Use a
small screwdriver to open the front cover and make changes to the settings.
The pre-set time delay is Test mode and light level is set at maximum
Refer to Figure 5 and 6.
1. Ensure the PIR Activity is enabled, red LED flashes, and PIR Sensitivity
is set to 100% (DIP switch 1 ON).
2. Ensure the Time Delay is set for Test Mode.
3. Ensure that the Light Level is at the maximum position (see" LIGHT
LEVEL ADJUSTMENT”).
4. Remain still. The red LED should not flash. The lights should turn off after
15 seconds. (If not, see “TROUBLESHOOTING.”)
5. Move around in front of the coverage area. The lights should turn on
automatically. When functional test is complete, set DIP Switches, Time
Delay and Light Level to the desired settings, and put the front cover
back on the sensor.

SENSOR ADJUSTMENT
The sensor may be adjusted to operate at the desired level of light under normal
lighting conditions of the immediate area.
To do so, turn the dial to point the arrow toward
the “-”sign for sensor to detect motion and
operate during low light or no light.
Point the arrow toward the “+”sign for
sensor to operate when there’s more light in
the area or even during daylight.
If the sensor detects occupancy during the warm-up, the time delay will
increase.
If no occupancy is detected during the warm-up,the light turns OFF after the
initial 60-second warm-up period.
