Backup for Wireless using a landline.
Since I noticed the phone jacks on the base unit, and being in electronic technology my entire life, I decided to call tech support today and ask them a question regarding the priority that the base unit uses for contacting the monitoring station, if a phone line is plugged into the phone jack. They stated that the base unit will still use the wireless connection first, and if that is not available, then it will use the landline. This would not result in any slowdown in contacting the monitoring station, in case of an alarm. So, it seems to me, that this is an excellent backup , if you do have a landline available, since it is like having two contact systems.
