Installation Procedure
Installation Precautions - Adherence to the following will aid in problem-free
installation with long-term reliability: WARNING - Several different sources of power
can be connected to the fire alarm control panel. Disconnect all sources of power
before servicing. Control unit and associated equipment may be damaged by
removing and/or inserting cards, modules, or interconnecting cables while the unit is
energized. Do not attempt to install, service, or operate this unit until manuals are
read and understood. CAUTION - System Re-acceptance Test after Software
Changes: To ensure proper system operation, this product must be tested in
accordance with NFPA 72 after any programming operation or change in site-specific
software. Re-acceptance testing is required after any change, addition or deletion of
system components, or after any modification, repair or adjustment to system
hardware or wiring. All components, circuits, system operations, or software functions
known to be affected by a change must be 100% tested. In addition, to ensure that
other operations are not inadvertently affected, at least 10% of initiating devices that
are not directly affected by the change, up to a maximum of 50 devices, must also be
tested and proper system operation verified. This system meets NFPA requirements
for operation within the range of 0°C-49°C (32°F-120°F) or humidity within the range
of 10%-93% at 30°C (86°F) noncondensing. However, the useful life of the system's
standby batteries and the electronic components may be adversely affected by
extreme temperature ranges and humidity. Therefore, it is recommended that this
system and its peripherals be installed in an environment with a normal room
temperature of 15-27º C/60-80º F. Verify that wire sizes are adequate for all
initiating and indicating device loops. Most devices cannot tolerate more than a 10%
I.R. drop from the specified device voltage. Like all solid state electronic devices,
this system may operate erratically or can be damaged when subjected to lightning
induced transients. Although no system is completely immune from lightning
transients and interference, proper grounding will reduce susceptibility. Overhead or
outside aerial wiring is not recommended, due to an increased susceptibility to
nearby lightning strikes. Consult with the Technical Services Department if any
problems are anticipated or encountered. Remove DC power prior to removing or
inserting circuit boards. Failure to do so can damage circuits. Remove all electronic
assemblies prior to any drilling, filing, reaming, or punching of the enclosure. When
possible, make all cable entries from the sides or rear. Before making modifications,
verify that they will not interfere with battery, transformer, or printed circuit board
location. Do not tighten screw terminals more than 9 in-lbs. Over-tightening may
damage threads, resulting in reduced terminal contact pressure and difficulty with
screw terminal removal. Fire alarm control panels contain static-sensitive
components. Always ground yourself with a proper wrist strap before handling any
circuits so that static charges are removed from the body. Use static suppressive
packaging to protect electronic assemblies removed from the unit.
Follow the instructions in the installation, operating, and programming manuals.
These instructions must be followed to avoid damage to the control panel and
associated equipment. FACP (Fire Alarm Control Panel) operation and reliability
depend upon proper installation.
Equipment used in the system may not be technically compatible with the control. It
is essential to use only equipment listed for service with your control panel.
Telephone lines needed to transmit alarm signals from a premise to a central
monitoring station may be out of service or temporarily disabled. The most common
cause of fire alarm malfunctions, however, is inadequate maintenance. All devices
and system wiring should be tested and maintained by professional fire alarm
installers following written procedures supplied with each device. System inspection
and testing should be scheduled monthly or as required by national and/or local fire
codes. Adequate written records of all inspections should be kept.

Overview
Limitations of Fire Alarm Systems
Requirements and recommendations for proper use of fire alarm systems including smoke detectors and other fire alarm devices:
• To keep your fire alarm system in excellent working order, ongoing maintenance is
required per the manufacturer’s recommendations and UL and NFPA standards.
At a minimum the requirements of Chapter 14 of NFPA 72, 2010 Edition shall be
followed. A maintenance agreement should be arranged through the local
manufacturer’s representative. Maintenance should be performed annually by
authorized personnel only.
The most common cause of an alarm system not functioning when a fire occurs is
inadequate maintenance. As such, the alarm system should be tested weekly to
make sure all sensors and transmitters are working properly.

Section 2 Before you Begin Installing
This section of the manual is intended to help you plan your tasks to complete the
installation. Please read this section thoroughly, especially if you are installing a SKFFT for the first time.
2.1 Environmental Specifications
It is important to protect the SK-FFT control panel from water. To prevent water
damage, the following conditions should be AVOIDED when installing the units:
• Do not mount directly on exterior walls, especially masonry walls (condensation)
• Do not mount directly on exterior walls below grade (condensation)
• Protect from plumbing leaks
• Protect from splash caused by sprinkler system inspection ports
• Do not mount in areas with humidity-generating equipment (such as dryers,
production machinery)
When selecting a location to mount the SK-FFT, the unit should be mounted where it
will NOT be exposed to temperatures outside the range of 0°C- 49°C (32°F-120°F) or
humidity outside the range of 10% - 93% at 30°C (86°F) noncondensing.
2.2 Preventing Water Damage
Water damage to the fire fighters phone system can be caused by moisture entering
the cabinet through the conduits. Conduits that are installed to enter the top of the
cabinet are most likely to cause water problems. Installers should take reasonable
precautions to prevent water from entering the cabinet. Water damage is not covered
under warranty.
2.2.1 Removing the SK-FFT Assembly from the Housing
If it should ever be necessary to remove the control panel assembly from the cabinet
for repair, do so by removing the screws that hold the control panel in to the cabinet.
Do not attempt to disassemble the circuit boards.

2.5 Wiring Specifications
Induced noise (transfer of electrical energy from one wire to another) can interfere
with telephone communication or cause false alarms. To avoid induced noise, follow
these guidelines:
• Isolate input wiring from high current output and power wiring. Do not pull one
multi-conductor cable for the entire panel. Instead, separate the wiring as follows:
SLC loops Audio circuits
Relay circuit
• Do not pull wires from different groups through the same conduit. If you must run
them together, do so for as short a distance as possible or use shielded cable.
Twisted, shielded wire on the Audio Circuits is recommended for maximum
protection against EMI and AFI emissions and susceptibility. Connect the shield to
earth ground at the panel. You must route high and low voltages separately.
• Route the wiring around the inside perimeter of the cabinet. It should not cross the
circuit board where it could induce noise into the sensitive microelectronics or pick
up unwanted RF noise from the high speed circuits. See Figure 2-4 for an
example.
• High frequency noise, such as that produced by the inductive reactance of a
speaker or bell, can also be reduced by running the wire through ferrite shield
beads or by wrapping it around a ferrite toroid.

Section 6 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.
6.1 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.
54711 6-1
SK-FFT Installation and Operation Manual
6.2 LED Operations
6.2.1 Power Status LED
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 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 goes silent. Communication 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 handset has disconnected
from the FFT, the answer LED will go blank and the system will be back 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 active when system troubles are detected. When
the Silence Key is pressed, the General Trouble LED will become constant. Once all
system troubles have been restored, the General Trouble LED will deactivate.

when a remote handset is plugged into that zone. The LED will turn off when the
handset is removed from the zone.
6.2.9 Zone Trouble
Each zone has a Trouble LED (see Figure 6-1). The zone's Trouble LED will blink
when specific SLC issues occur such as a missing device or double address.
Pressing the Silence Key will cause the zone trouble LED to be on solid. Once the
zone trouble is corrected, the LED will turn off.

allow the user to accept the configuration, repeat the JumpStart or allow the
configuration to be discarded.
1. To perform the FFT Jumpstart press and hold the JumpStart button for 2 seconds.
2. The FFT will search for installed SLC devices and activate the Active LED’s of all
zone/point addresses found.
3. When the Jumpstart is complete, the first four status LED’s will blink. The user can
now press the ACCEPT key causing the FFT to save the configuration and
restart.
4. The user presses the JumpStart key again to repeat the SLC search process.
5. 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.
