Programming the IFAMFFT module for emergency telephone lines

The programming section of the IFAMFFT module, reachable from the Previdia Ultra control panel programming page, allows the configuration of each of the 4 emergency telephone lines it provides:

[A] 

Layout of the module where you can select the line terminal

[B] 

Section with the parameters of the selected line

Once the line has been selected, clicking on the relative terminal allows you to set its parameters:

  • Label – 20 character string that the control panel will use to identify the line

  • Enrolled – option that activates the line

  • Open fault threshold – field for the resistance value expressed in ohms, measured on the line, above which the control panel will signal a fault.

  • Handset off-hook threshold – field for the line consumption, expressed in mA, above which one of the handsets of the telephones connected to the line will result off-hook.

  • Loop wiring – field for the type off wiring used for the line:

    • standard, connection in line mode

    • loop connection

    • loop with isolators
