System Operation
The operation of the SK-FFT Fire Fighter Telephone system allows audio
communication from 24 remote connections through remote handsets from a single
local handset. Up to 10 remote handset can be connected and communicating at one
time. Remote audio connections can be expanded to 48 with the optional FFT-24
zone expander.

Key Switch Operations
6.1.1
JumpStart Key Switch (on inside of FFT dead front
panel).
JumpStart key will cause the FFT to search the SLC loop for devices. The Active LED
(green) will then blink for each zone where a device was found. Press and hold the
Jumpstart Key for 2 seconds in order to initiate Jumpstart.
6.1.2
Accept Key Switch (on inside of FFT dead front
panel).
The Accept key is used after Jumpstart. It will save the current SLC device
configuration and re-initialize the FFT. If the user does not press the Accept key
within one minute after the JumpStart is complete, its configuration will be discarded
and the FFT will be restarted.
6.1.3
Answer Switch
When a Remote Handset is connected to one of the FFT-FPJ phone jacks, the
Answer LED will blink and the FFT's PZT will sound. Pressing the Answer Switch will
connect the local handset to the phone circuit, turn the answer LED on solid, and
silence the PZT. Communication between the local and remote handset is now
possible. Up to six remote handsets can be connected to the phone circuit
simultaneously. After the initial remote handset, the connection of additional handsets
does not cause the PZT to sound or the Answer LED to blink.
6.1.4
Silence Switch
The Silenced Switch is used to silence a system type trouble that has occurred in the
FFT system. Once pressed the PZT will silence.
