Section 3: System Operation
The operation of the ECC-FFT Fire Fighter Telephone system allows audio communication from
24 remote connections through remote handsets to a single local handset. Up to 10 remote handsets
can be connected and communicating at one time.
3.1 Push-button Operations
Autoprogram (on inside of FFT dress panel)
The Autoprogram 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 Autoprogram
button for 2 seconds in order to initiate this feature.
Accept (on inside of FFT dress panel)
The Accept button is used after Autoprogram. It will save the current SLC device configuration and
re-initialize the FFT. If the Accept button is not pressed within one minute after the Autoprogram is
complete, its configuration will be discarded and the FFT will be restarted.
Answer Call
When a remote handset is connected to one of the FPJ-F phone jacks, the Answer Call LED will
blink and the FFT's piezo will sound. Pressing the Answer Call button will connect the local hand-
set to the phone circuit, turn the Answer Call LED on steady, and silence the piezo. Communication
between the local and remote handset is now possible. Up to ten remote handsets can be connected
to the phone circuit simultaneously. After the initial remote handset, the connection of additional
handsets does not cause the piezo to sound or the Answer Call LED to blink.
Trouble Silence
The Trouble Silence button is used to silence a system type trouble that has occurred in the FFT
system. Once pressed, the piezo will silence.
3.2 LED Operations
Power Status LED (on Inside of FFT dress panel)
The status LED is located on the right side of the FFT board. On power-up, the power status LED
will blink at a 50% on/off rate until FFT initialization is complete (which takes approximately 20
seconds). Once initialization is complete, the status LED will blink at a 10% on and 90% off rate.
No key input will be valid until the FFT completes its initialization.
Answer Call
When a remote handset connects to the audio channel, the Answer Call LED will blink and the
piezo will sound. The operator at the FFT then picks up the local handset and presses the Answer
button which causes the Answer Call LED to remain on steady and the piezo goes silent. Commu-
nication between the local and remote handset is now established. Additional remote handsets can
be attached to the audio connection without any intervention at the FFT. Once the last remote hand-
set has disconnected from the FFT, the answer LED will turn off and the system will return to nor-
mal.
Power
The Power LED indicates that 24 VDC is connected to the FFT.
Local Trouble
The local handset trouble LED will activate and blink when there is a problem with the local hand-
set.
