Alula BAT-CONNECT Universal Alarm Communicator

Is this communicator the Alula BAT-Connect-V Universal Alarm Communicator (Verizon), Sunset-Proof Communicator with Ethernet and Wi-Fi On Board, 5G ready? Does it need the PC link RE049 cable to operate with a DCS PC1616? And can it be registered to operate Wi-Fi and/or Ethernet only (self-monitor) (to eliminate the interactive service fee)? And does your company register with Alula to activate for me?

Yes.
The RE049 is an optional cable that is not required for the device to work. It just syncs the zone information into the Bat automatically.
There is no way around the interactive fee. Alula still provides those services even over IP and wants to be paid for their services.
Yes, if you purchase the service from us, we register and activate the device.

Besides the yearly interactive service fee($150.00), does the Alula BAT-CONNECT Universal Alarm Communicator require its own cell service along with a fee and number from Verizon?

No, the cell service is inclusive for the $150 fee.

We have an old wired alarm system that we are wanting to convert to a cell system. Inside the alarm box, the wording is Sp Spectra MGSPCP V3.01 "Stay D" V4.6D 51/09. We were looking at the Alula, but were not able to tell if our system could be converted. Can you help? Can you help? Is it a lost cause? We would really like to use our hard wired connections if at all possible but would like to update the system and use cell phones instead of a landline. Thanks in advance for your help.

No one here has heard of a Spectra alarm and it's certainly not mentioned in the Alula as a compatible model. I'd just replace the main board and keypad. You can keep all you hardwired sensors.
