you are completely misreading it, and if you are using it for alarm reporting (monitoring via Alarmnet) I'd love to see how without using a standard CS, as Alarmnet is not a CS.
Alarmnet transfers the signals they recieve to a CS that can recieve Alarmnet signals. Monitoring, account management, as well as something down to contact with authorities and yourself, are not done with Alarmnet.
The only thing the 8132I will do is emulate the same signals that are sent via Ademco's LRR (Alarmnet C) units using TC/IP protocol.
The Symphony, by enabling via programming, enables an Alarmnet-I communications path. It's basically emulating the Alarmnet-I transceiever that they are selling for all the ECP enabled panels, without the Symphony interface.
Mind you, none of this is available to an end user, as end users are not Alarmnet or Ademco dealers, and don't have access to such. Anyone can buy the units, but without a dealer account with Alarmnet and access to a CS that can recieve Alarmnet signaling, the feature is moot.
Also, not having multiple communication routes and formats (standard dialer) and an always on network connection, as the same issues with running communications via a network applies (almost similar to the VOIP argument) of having no backup power to the network connection, and still having it communicate via wire (same as POTS).
I have yet to see any dealers in my state install one of these as a TC/IP protocol connection only, and I will say doing such, without a secondary form of communications (would have to be POTS, as the LRR feature is already programmed for the internet reporting) otherwise full data transmission would not be possible, is a very foolhardy way to proceed.
