The HAI C3 is a great alternative GSM communicator for those who want to self monitor or have central station monitoring and don't have a land-line phone line. The C3 is the best thing we've found since for self-monitoring GSM communication since we started carrying the Dock N Talk module.

This unit not only wires into your alarm panel like a phone line but you can also plug land-line telephones into it to make calls out over the cellphone frequency. This unit accepts a SIM card that you provide either from a contract plan you have or from a pre-paid service plan. This allows you to have the system call out to you or a central station monitoring service. You can view a video describing this module in detail HERE
