Use twisted pair shielded cable for telephone circuit wiring. For
best operation, terminate shield at FFT-7/S 24V power supply
common (-).
Maximum telephone circuit wire resistance is 40 ohms.
For ELR connection to devices with terminals, use Resistor 71252.
For ELR connection to devices with flying leads, use
Resistor 71245. In Canada, N-ELR Resistor Assembly is required.
Refer to the fire panel manual for UL power-limited requirements
