WIRING AND INSTALLATION
WARNING: Turn off the power at the circuit breaker before installing
Refer to the wire diagram of the sensor (see figure 4), and connect the wires of
ceiling sensors as followed by using the wire nuts provided.
1. Connect the Hot wire to the Black wire from the sensor.
2. Connect the Load wire to the Red wire from the sensor.
3. Connect the Neutral wire to the White wire from the sensor.
4. You can add a Manual Switch to the sensor by connecting the Grey wires to a
momentary switch.
(Step 4 is not necessary if you don't want to use the function of MANUAL ON/OFF )

Using an Octagonal Junction Box
1. Pull the pre-stripped color wires into the J-Box through the conduit knockout.
2. Connect the pre-stripped color wires to the appropriate terminals on the sensor.
3. Loosen the appliance mounting screws attached to the J-Box.
4. Align the sensor in the J-Box so that the mounting s
crews on the box match the
key holes on the sensor's rear housing
5. Push the sensor up into the J-Box and twist it so that the mounting
screws are seated in the keyhole slots.
6. Tighten the two screws to secure the sensor to the J-Box.
7. Snap the front cover onto the sensor (see Figure
5)

SENSOR PLACEMENT
DESCRIPTION

When designing a sensor solution for any room, its important to keep in mind
the focus points of the room such as furniture layout, air vents, light fixtures.
The sensor should place 4 to 6 ft away from air flow source and any climate
system. The sensor will false trigger the lighting system when rapid
temperature change detected by the device and consider it as movement.
MPC-50V 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.
Another important thing to note is that its not necessary to have occupancy
sensor coverage on every square inch of space in any particular rooms.
Simply these spaces generally have many people moving around in them.
Often the best location to install multiple MPC-50V is in the walkways of an
open office space. (see Figure 1)
The MPC-50V 360° passive infrared (PIR) occupancy sensor use PIR
technology
and advanced ambient light level to turn on the lighting system
when
movement is initially detected with insufficient ambient light, and keep
the lights on as long as movement is present The sensor will automatically
turn off the light system after no movement is detected and the preset time
delay has expired.
Figure 1
a. 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.
b. The sensors should not cover the employee cubicles, entrances, and any other areas
where people might sit for long periods of time.

COVERAGE PATTERN
The MPC-50V provides a 360° coverage pattern, up to 1200 square feet. The coverage shown
represents walking motion at a mounting height of 8 feet (See Figure 3 ). The sensor is
designed to detect a heat-emitted movement across its coverage zone of view, and less
sensitive to lower levels of activity or with obstacles or barriers.

LIGHT LEVEL ADJUSTMENT
Turn the potentiometer on the sensor to the "-” if adequate ambient light
The output of sensor will be inhibited, and the load can not be turn on, only
when the ambient light is down to a certain level the sensor will automatically turn on.
Therefore, potentiometers require customers to adjust in accordance with the
location and the ambient light level.
Turn the potentiometer on
the sensor to the "+”, regardless of the ambient light
level. The load will be on as
long as there are signals from occupancy.
1. Avoid mounting the sensor close to lighting fixtures.
2. Adjust during daylight hours when ambient light in
the area is at desired level. Open the Front Cover
and adjust the Light level.
