The Zone Protector MAC address format  is as follows:

00-04-A3 XX XX XX

Where XX XX XX is the alphanumerical serial number of the individual Zone Protector device.

The serial number label can be found on the rear of the Zone Protector and on the device information page

(Note: The 00-04-A3 aspect of the MAC address is common on all Zone Protector devices. The serial number of each individual Zone Protector is the unique aspect of the MAC address… An example of a Zone Protector MAC address might be 00-04-A3-1D-32-4C)
