FFT

The FFT Fire Fighter T elephone Module provides supervision,
annunciation and control for local and remote telephone handsets as
well as an optional remote microphone.

CAUTION! Make sure to observe all of the following precautions:

• Remove all power (AC and DC) before installing or removing any modules since damage to components
may occur if power remains applied.

• Circuit boards contain static-sensitive components. Always ground yourself with a proper wrist strap
before handling any boards so that static charges are removed from the body. Use static suppressive
packaging to protect electronic assemblies.

FFT Replacement

1. Make certain that AC and DC power have been removed from the panel.

2. Unplug the terminal block connectors from TB1, TB2 and TB3 located on the top edge of the defective FFT board
(label to ensure reinstallation in correct positions).

3. Unplug the panel telephone handset from Phone Jack J1 located on bottom center of the defective FFT board.

4. Remove two mounting screws which hold the defective FFT board to the mounting bracket standoffs and set aside.

5. Carefully lift the defective FFT board from the slot in the bottom of the mounting bracket.

6. Remove the ribbon cable connectors from J2 on the right side of the board and J3 on the back of the defective FFT
board.

7. Connect cable between J2 on the new FFT board and P5 on Zone Split Audio Panel main circuit board as illustrated
below.

8. If telephone call-ins are to be annunciated on the ZPM, connect cable between J3 on the FFT and P4 on the back
of the ZPM(K) module. Note that the J3 and P4 ribbon cable connectors are keyed to prevent incorrect

installation. Refer to following illustration for connector locations.
