Monitoring Questions

My phone lines were cut, why didn’t you call and tell me?

The dialer for the alarm system is located inside your home, there is no way for us to determine if the phone line has been cut.  The system relies on the phone line to communicate.  However, many systems can have cell phone back up modules added to them.  These modules give you that extra protection should the standard phone line become unusable for whatever reason.
