That Arrowhead phone-to-IP module is only $55 less than what Garrisonalarms is charging for a phone-to-4G module, new battery, and the installation of both if you sign up to their monitoring.

 

 

 

Been through this with family - phone calls and emails about how your 3G device needs to be replaced with a whole new unit. Except it doesn't use 3G. So I wonder how many just agreed to upgrades of fixtured devices for the 3G shutdown without understanding their true situation. 

 

I had an offer from another company to install their 4G module which would work with the DSC and switch to their monitoring services. That would cost me $170+G in total and $36/month. But the system has no remote activation and monitoring for me and would only call the alarm company.

The 3G module is not only used to call the alarm company but also provides internet access to ADT's alarm.com SAS service which you can use to remotely tunrn/off your alarm.  Like this
