Sending Explicit Messages
A SmartGuard controller can send explicit messages from a user
application program. User-registered messages are sent over the
network when user-specified trigger conditions are met. This can be
used to notify monitoring and control devices or as a method for
specifying outputs to display devices. Up to 32 bytes of explicit
message data can be sent.
