Section 6: System Operation; Keyswitch Operations; 1: Jumpstart Key; 2: Accept Key - Honeywell Farenhyt Series Manual

The operation of the IFP-FFT Fire Fighter Telephone System allows audio communication from 24 remote connections through remote
handsets from a single local handset. Up to 10 remote handsets can be connected and used for the remote communication at one time.
Remote audio connections can be expanded to 72 using the optional FFT-24 Zone Expander.

6.1 Keyswitch Operations

6.1.1 JumpStart Key
The JumpStart key, located on the inside of the dead front panel, will cause the FFT to search the SLC loop for devices. The Active LED
(green) blinks for each zone where a device was found. Press and hold the JumpStart key for 2 seconds in order to initiate JumpStart Auto-
programming.
6.1.2 Accept Key
The Accept key is used after JumpStart. It will save the current SLC device configuration and re-initialize the FFT. If you do not press the
Accept key within one minute after JumpStart is complete, the configuration will be discarded and the FFT will restart.
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 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 trouble that has occurred in the FFT system. Once pressed, the PZT will silence.

6.2 LED Operations

6.2.1 Power Status
The Power Status LED is located on the left side of the FFT board. On power-up, the Power Status LED will blink at a 50% ON/OFF rate
until the FFT initialization is complete (which takes approximately 20 seconds). Once initialization is complete, the Power Status LED will
blink at a 10% ON and 90% OFF rate.
No key input will be valid until the FFT completes its initialization.
6.2.2 Answer
When a remote handset connects to the audio channel, the Answer LED will blink and the PZT will sound. The operator at the FFT then
picks up the local handset and presses the Answer Switch which causes the Answer LED to remain on solid and the PZT to silence. Commu-
nication between the local and the remote handset is now established. You can attach additional remote handsets to the audio connection
without any intervention at the FFT. Once the last remote handset has disconnected from the FFT, the Answer LED will turn off and the sys-
tem returns to normal.
6.2.3 Power
The Power LED indicates that 24 VDC is connected to the FFT.
6.2.4 Local Handset Trouble
The local Handset Trouble LED will activate and blink when there is a problem with the local handset.
6.2.5 Remote Handset Trouble
The Remote Handset Trouble LED will activate and blink when there is a problem with the phone circuit.
6.2.6 General Trouble
The General Trouble LED will blink the when system troubles are detected. When you press the Silence key, the General Trouble LED will
become constant. After all system troubles are restored, the General Trouble LED will turn off.
6.2.7 Status LEDs
The following LEDs are located on the inside of the FFT dead front panel.
• LED 1 - SLC supervision (turns on when there is an open/short on the SLC or when an incorrect device type is detected)
• LED 2 - SLC extra point detected
• LED 3 - FFT-24 missing
• LED 4 - Audio circuit supervision
