The MD3 is a wired motion sensor. Use the MD3 in conjunction with the FMS, F200, or WiNG-MGR to monitor motion.
Make sure you have the right power supply!
The MD3 requires a power supply.
If you use this sensor with and wire it directly to an FMS, the sensor will be powered by the FMS itself.
If you use the MD3 with any of our other controllers, including the F200 or WiNG-MGR, you need to purchase a WA-DC-12 power supply to power the sensor.
