Clear a Phone Line Failure on an Interlogix Simon XTi-5

Clearing a Phone Line Failure on an Interlogix Simon XTi-5/i depends on if there is a phone line connected to the panel. A Phone Line Failure, also known as TLM/PLF/FTC, occurs if the panel either:

  • Has a phone line attached to the panel but the phone line is unable to communicate.
  • Has monitoring station information programmed into it but the panel does not have a phone line attached to it. 

If a phone line is connected:

  • Resolve the phone line communication.

For more information about connecting or troubleshooting the phone line locally, contact the panel manufacturer.

If a phone line is not connected:

If there is no phone line attached, it is required to remove the monitoring station information programmed from the panel because the information is stored in the module.

The monitoring station account information can be cleared remotely using the Partner Portal or Partner MobileTech app, or locally at the panel. All of these methods require a local power cycle of the panel.
