Testing the System
Testing the Power Failure Transfer Jacks
To test a power failure transfer (PFT) jack for proper operation, you must assign
the outside line numbers to the module’s line/trunk jacks and the trunks must be
operational. A PFT telephone on a GS line must have a GS button attached to
the telephone. See Figure 7-1
.

To test PFT jacks, follow the steps below:
Plug a touch-tone or rotary dial telephone into a PFT jack.
Note the outside line number assigned to the lowest line/trunk jack
on the module and be sure that the outside trunk is connected to
the system.
Turn off power to the control unit.
Follow the procedure in ‘‘
Powering Down the System’’ in Chapter 9.
If the telephone is connected to a GS trunk, push the GS button
attached to the telephone.
Pick up the handset on the touch-tone or rotary dial telephone.
You should hear a dial tone.
