How do I decode a sensor's Tamper Event message?

The sensor will send a message when the tamper switch has been either opened or closed through either an enclosure tamper or a wall mount tamper.

Tamper Event Message: 0x02
      Bytes            Description
      0                   Tamper Switch State (Open = 0x00, Closed 0x01)

Tamper Event Message Example:

      1 0 02 00

      1                     Protocol Version (currently always 0x1)
      0              Packet Counter (increments by 1 each message and wraps from 0xF to 0x0)
      02              Message Type Code (Tamper Event = 0x02)
      00              Tamper Switch State (Opened = 0x00)

      Not all sensors support the tamper feature. See the individual datasheets for more information.
