4. The chase nipple provided can be pushed into a standard 1/2”
The MPC-50H can be attached to the fixture or junction box using the
back box and chase nipple or directly to the fixture surface via the two
screw holes provided in the sensor (See Figure 3 below).

Back box mounting
This requires a standard 1/2” knockout for the chase nipple.The Sensor
mounts to the back box with a bayonet type fitting requiring a slight
twist of the units to separate them or lock them into place.The box
comes ready for side mounting(See Figure 4). It can be modified
for rear mounting as follows:
1. Pop out the cap in the rear 1/2'' knockout.
2. Un-snap the chase nipples from the side mount and snap into the
rear mounting hole.
3. Use the cap to close the side mount hole.
knockout in a metal fixture [max of 1 mm (0.04”) thick metal]
without the need for the included internal nut. The nut can be
used for added security if necessary.
Note: There is a 60-second warm-up period when power is
first applied, LED flashes
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.
The sensors are factory preset to allow for quick installation in most
applications.After test is finished,adjust the potentiometer according

LED does not blink:
from human body. If not , the LED will not blinks.
LED blinks but lights do not turn ON:
1.Make sure the wire connections are correct. Red load wire lead to
load light, and check the connection security.
2.Make sure that power to the sensor has been ON continuously for
at least one minute. Wait for the warm-up period to end,and if LED
flashes,the load has not turn on,then go to next step.
3.Cover the light sensor lens to simulate darkness.If the light turns
ON,the light level setting needs to be adjusted.If set for minimum,
more than 2fc of ambient light causes the lights to be held OFF.
4.Check security of the light fixture.
Lights will not turn OFF:
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
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 time delay set 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.
Sensitivity setting: DIP switch 1
1. 50%,sensor’s coverage is smaller, just about half of the widest range.
2. 100%,the maximum range of MPC-50H-L1 coverage is 2800 square
feet,while for MPC-50H-L2 coverage is 1200 square feet.
Time delay: DIP switch 2,3,4
The sensor will hold on the lights on as long as occupancy is detected.
The time delay countdown starts when no motion is detected.After no
motion is detected for the length of the time delay, the sensor will turn
the lights off.
The MPC-50H has 4 DIP switches under the cover.They are used to
set sensitivity and time delay feature settings.
