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.

3.1 Mounting the Cabinet
Read the environmental specifications in Section 2.1 before mounting the SK-FFT
cabinet. This will ensure that you select a suitable location.
The cabinet can be surface or flush mounted. Do NOT flush-mount in a wall designed
as a fire break.
3.1.1 Surface Mounting
The Cabinet can be mounted on the wall surface by using the mounting holes in the
back of the cabinet (see Figure 3-1).
1. Insert two screws level with each other, 14" apart for the top cabinet key shaped
holes. See Figure 3-1.
2. Hang the cabinet onto the two screws. Tighten the screws down.
3. Insert two screws into the two bottom mounting holes and tighten them snug to the
cabinet.

3.1.2 Flush Mounting
This section describes how to flush mount the cabinet into a wall. To recess mount
the cabinet you will need to have the optional trim ring P/N VIP-TR (ordered
separately).
Follow these steps to recess mount the cabinet:
1. Remove the cabinet door and the dead front panel.
2. Cut a recess hole 20-1/4” W x 26-3/4” H (51.44 cm W x 67.95 cm H). There
should be 1.5" to 1.75" of cabinet extruding from the wall, this should be measured
from either the top edge or bottom edge to the exterior side of the sheet rock. (See
Figure 3-2.)
Important!
Do not insert the cabinet deeper than recommend above. If the cabinet is mounted to deep you will
not be able to re-attach the door assembly.
3. Mount the cabinet to wall studs by inserting a screw through the cabinets side
mounting holes into the wall stud.
