5] Technical Specifications (continued)

The Magnum Energy Solutions (MES) Motion and Lux sensor (Mx-ML2) is a wireless, self powered, passive 

infrared sensor that ensures reliable detection of occupant presence. The Mx-ML2 is ideally suited for occupancy 

based lighting control and also provides for indoor daylight harvesting functionality, with a light range of 0-1020lx. 

When paired with a relay (Mx-USR-L1) and a wireless rocker switch (Mx-ESRP), the sensor creates an out of the 

box, cost effective, lighting control system. When combined with an MES gateway (Mx-EBOX), the Mx-ML2 can be 

integrated into an existing BACnet-compatible building automation system.

Built in solar cells draw and store energy from available ambient light to power the device and keep it operational 

during periods of darkness. The device must be placed at the location where sensing is required and this location 

is dependent on individual application (refer to Sensor Placement Tips below). An optional battery back up is 

available for locations with low or no ambient light. The Mx-ML2 must be paired with a receiver (refer to Compatible 

Devices section). The device can be paired manually to compatible devices by pressing the LRN button while 

following the pairing instructions for the receiver. For more sophisticated configuration, please refer to the MES 

AirConfig tool available at

.

The sensor can be mounted using screws or simply 

placed in selected location with double stick tape. It is recommended that the pairing of this device be done prior 

to installing the ceiling sensor.

LRN Button

Press and release the LRN button. The red LED light should 

flash once, signaling the device has sent a “learn” message to 

identify itself with compatible devices within wireless range

Please refer to the corresponding device installation guides to 

review the process of learning this sensor with compatible devices.

NOTE: It is recommended that pairing of device be done prior to installing the ceiling sensor.

NOTE: Place the sensor under bright light for 1 or more minutes to gather energy to begin functioning.
