360 Degrees 120/277VAC Dual Technology Occupancy Sensor Ceiling Mount


360 Degrees 120/277VAC Dual Technology Occupancy Sensor Ceiling Mount


The MDC-50V 360 Degrees Dual-Technology Occupancy Sensor combines advanced passive infrared (PIR) and ultrasonic technologies into one  unit. The combined technologies help to avoid false triggering. Selectable operating modes allow the sensor to turn a load on, and hold it on as long as either or both technologies detect occupancy. After no movement is detected 

for the selected time delay, the lights switch off.

Coverage Pattern:

The MDC-50V provides a 360° coverage pattern. The coverage shown represents walking motion at mounting height of 9 feet. For building spaces with lower levels of activity or with obstacles and barriers,coverage size may decrease.


Wiring Directions:

WARNING: Turn off the power at the circuit breaker before installing.

Refer to the wire diagram of the sensor,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.



Using an octagonal junction box 

1.Pull the high voltage wires into the J-BOX through the conduit knockout.

2.Connect the high voltage wires to the appropriate teminals on the sensor.

3Loosen the app;oance mounting screws attached to the J-BOX.

4.Align the sensor in the J-BOX so that the mounting screws 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.
