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 pairs manually to compatible devices by pressing the LRN button. For more sophisticated configuration, please refer to the MES AirConfig tool available at download.magnumes.net. 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.
