Fire Alarm & Emergency Communication System Limitations
While a life safety system may lower insurance rates, it is not a substitute for life and property insurance!
An automatic fire alarm system—typically made up of smoke
detectors, heat detectors, manual pull stations, audible warning
devices, and a fire alarm control panel (FACP) with remote
notification capability—can provide early warning of a developing fire.
Such a system, however, does not assure protection against property
damage or loss of life resulting from a fire.
An emergency communication system—typically made up of an
automatic fire alarm system (as described above) and a life safety
communication system that may include an autonomous control unit
(ACU), local operating console (LOC), voice communication, and
other various interoperable communication methods—can broadcast
a mass notification message. Such a system, however, does not
assure protection against property damage or loss of life resulting
from a fire or life safety event.
The Manufacturer recommends that smoke and/or heat detectors be
located throughout a protected premises following the
recommendations of the current edition of the National Fire Protection
Association Standard 72 (NFPA72), manufacturer's
recommendations, State and local codes, and the recommendations
contained in the Guide for Proper Use of System Smoke Detectors,
which is made available at no charge to all installing dealers. This
document can be found at http://www.systemsensor.com/appguides/.
A study by the Federal Emergency Management Agency (an agency
of the United States government) indicated thatsmoke detectors may
not go off in as many as 35% of all fires. While fire alarm systems are
designed to provide early warning against fire, they do not guarantee
warning or protection against fire. A fire alarm system may not
provide timely or adequate warning, or simply may not function, for a
variety of reasons:
Smoke detectors may not sense fire where smoke cannot reach the
detectors such as in chimneys, in or behind walls, on roofs, or on the
other side of closed doors.Smoke detectors also may notsense a fire
on another level or floor of a building. A second-floor detector, for
example, may not sense a first-floor or basement fire.
Particles of combustion or “smoke” from a developing fire may not
reach the sensing chambers of smoke detectors because:
• Barriers such as closed or partially closed doors, walls, chimneys,
even wet or humid areas may inhibit particle or smoke flow.
• Smoke particles may become “cold,” stratify, and not reach the
ceiling or upper walls where detectors are located.
• Smoke particles may be blown away from detectors by air outlets,
such as air conditioning vents.
• Smoke particles may be drawn into air returns before reaching the
detector.
The amount of “smoke” present may be insufficient to alarm smoke
detectors. Smoke detectors are designed to alarm at various levels of
smoke density. If such density levels are not created by a developing
fire at the location of detectors, the detectors will not go into alarm.
Smoke detectors, even when working properly, have sensing
limitations. Detectors that have photoelectronic sensing chambers
tend to detect smoldering fires better than flaming fires, which have
little visible smoke. Detectors that have ionizing-type sensing
chambers tend to detect fast-flaming fires better than smoldering
fires. Because fires develop in different ways and are often
unpredictable in their growth, neither type of detector is necessarily
best and a given type of detector may not provide adequate warning
of a fire.
Smoke detectors cannot be expected to provide adequate warning of
fires caused by arson, children playing with matches (especially in
bedrooms), smoking in bed, and violent explosions (caused by
escaping gas, improper storage of flammable materials, etc.).
Heat detectors do not sense particles of combustion and alarm only
when heat on their sensors increases at a predetermined rate or
reaches a predetermined level. Rate-of-rise heat detectors may be
subject to reduced sensitivity over time. For this reason, the rate-of-
rise feature of each detector should be tested at least once per year
by a qualified fire protection specialist. Heat detectors are designed to
protect property, not life.
IMPORTANT! Smoke detectors must be installed in the same room
as the control panel and in rooms used by the system for the
connection of alarm transmission wiring, communications, signaling,
and/or power. If detectors are not so located, a developing fire may
damage the alarm system, compromising its ability to report a fire.
Audible warning devices such as bells, horns, strobes, speakers
and displays may not alert people if these devices are located on the
other side of closed or partly open doors or are located on another
floor of a building. Any warning device may fail to alert people with a
disability or those who have recently consumed drugs, alcohol, or
medication. Please note that:
• An emergency communication system may take priority over a fire
alarm system in the event of a life safety emergency.
• Voice messaging systems must be designed to meet intelligibility
requirements as defined by NFPA, local codes, andAuthorities
Having Jurisdiction (AHJ).
• Language and instructional requirements must be clearly dissemi-
nated on any local displays.
• Strobes can, under certain circumstances, cause seizures in peo-
ple with conditions such as epilepsy.
• Studies have shown that certain people, even when they hear a
fire alarm signal, do not respond to or comprehend the meaning of
the signal.Audible devices, such as horns and bells, can have dif-
ferent tonal patterns and frequencies. It is the property owner's
responsibility to conduct fire drills and other training exercises to
make people aware of fire alarm signals and instruct them on the
proper reaction to alarm signals.
• In rare instances, the sounding of a warning device can cause
temporary or permanent hearing loss.
A life safety system will not operate without any electrical power. If
AC power fails, the system will operate from standbybatteries only for
a specified time and only if the batteries have been properly
maintained and replaced regularly.
Equipment used in the system may not be technically compatible
with the control panel. It is essential to use only equipment listed for
service with your control panel.
Alarm Signaling Communications:
•IP connections rely on available bandwidth, which could be lim-
ited if the network is shared by multiple users or if ISP policies
impose restrictions on the amount of data transmitted. Service
packages must be carefully chosen to ensure that alarm signals
will always have available bandwidth. Outages by the ISP for
maintenance and upgrades may also inhibit alarm signals. For
added protection, a backup cellular connection is recommended.
•Cellular connections rely on a strong signal. Signal strength can
be adversely affected by the network coverage of the cellular car-
rier, objects and structural barriers at the installation location. Uti-
lize a cellular carrier that has reliable network coverage where the
alarm system is installed. For added protection, utilize an external
antenna to boost the signal.
•Telephone lines needed to transmit alarm signals from a premise
to a central monitoring station may be out of service or temporarily
disabled. For added protection against telephone line failure,
backup alarm signaling connections are recommended.
The most common cause of life safety system malfunction is
inadequate maintenance. To keep the entire life safety 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 NFPA 72 shall be followed.
Environments with large amounts of dust, dirt, or high air velocity
require more frequent maintenance. A maintenance agreement
should be arranged through the local manufacturer's representative.
Maintenance should be scheduled as required by National and/or
local fire codes and should be performed by authorized professional
life safety system installers only. Adequate written records of all
inspections should be kept. Limit-F-2020

Installation Precautions
Adherence to the following will aid in problem-free installation with long-term reliability:
WARNING - Several different sources of power can be con-
nected 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 inter-
connecting cables while the unit is energized. Do not attempt to
install, service, or operate this unit until manuals are read and under-
stood.
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 at 0-49º C/32-
120º F and at a relative humidity 93% ± 2% RH (non-condensing) at
32°C ± 2°C (90°F ± 3°F). 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 susceptibil-
ity. 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.
Disconnect AC power and batteries prior to removing or inserting
circuit boards. Failure to do so can damage circuits.
Remove all electronic assemblies prior to any drilling, filing, ream-
ing, 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.
This system contains 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 sup-
pressive packaging to protect electronic assemblies removed from
the unit.
Units with a touchscreen display should be cleaned with a dry,
clean, lint free/microfiber cloth. If additional cleaning is required,
apply a small amount of Isopropyl alcohol to the cloth and wipe
clean. Do not use detergents, solvents, or water for cleaning. Do not
spray liquid directly onto the display.
Follow the instructions in the installation, operating, and program-
ming manuals.These instructions must be followed to avoiddamage
to the control panel and associated equipment. FACP operation and
reliability depend upon proper installation.

Section 2: Prerequisites for Installation
This Section of the Manual is intended to help you plan your tasks to complete the installation. Please read this Section thor-
oughly, especially if you are installing a TR-FFT for the first time.
2.1 Environmental Specifications
It is important to protect the TR-FFT control panel from water. To prevent the water damage, the following conditions should
be AVOIDED when you install the units:
• Do not mount the panel directly on exterior walls, especially masonry walls (condensation).
• Do not mount the panel directly on exterior walls below grade (condensation).
• Protect the panel from plumbing leaks.
• Protect the panel from splash caused by sprinkler system inspection ports.
• Do not mount the panel in areas with humidity-generating equipment (such as dryers, production machinery).
When you select a location to mount the TR-FFT, the unit must be mounted where it will NOT be exposed to temperatures out-
side the range of 0°C- 49°C (32°F-120°F) or humidity outside the range of 10% - 93% at 30°C (86°F) non-condensing.
2.2 Preventing Water Damage
Water damage to the Fire Fighter’s Phone System can be caused by moisture entering the cabinet through the conduits. Con-
duits 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. The water damage is not covered under the warranty.
2.2.1 Removing the TR-FFT Assembly from the Housing
If it is necessary to remove the control panel assembly from the cabinet for repair, remove the screws that hold the control
panel in the cabinet. Do not attempt to disassemble the circuit boards.

Wiring Specifications Prerequisites for Installation
2.5 Wiring Specifications
Induced noise (such as, the transfer of the electrical energy from one wire to another wire) can interfere with the telephone
communication or cause false alarms. To avoid the induced noise, follow these guidelines:
• Isolate the input wiring from the high current output and the power wiring. Do not pull one multi-conductor cable for the
entire panel. Instead, separate the wiring as follows:
• Do not pull the wires from the different groups through the same conduit. If you must run them together, do so for as short
a distance as possible or use the shielded cable. Twisted, shielded wire on the audio circuits is recommended for the
maximum protection against EMI and AFI emissions and susceptibility. Connect the shield to the Earth Ground at the
panel. You must route the high and the 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 2.5 on
page 11 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 the ferrite shield beads or by wrapping it around a ferrite toroid.
2.6 Wire Routing
You must follow the power-limited wiring techniques, which include maintaining a one-quarter inch spacing between the
power-limited and the non-power limited circuits and separating the high and the low voltage circuits.

Section 3: Installation
3.1 Mounting the Cabinet
Read the Environmental Specifications in Section 2.1 before you mount the TR-FFT cabinet. This will ensure that you select a
suitable location.
The TR-FFT 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. To secure the cabinet to the wall, use the mounting holes in the back of the
cabinet (see Figure 3.1 on page 12).
1. Insert two screws level with each other, spacing 14" (.36cm) apart for the top cabinet key-shaped holes. See Figure 3.1 on
page 12.
2. Hang the cabinet onto the two screws. Tighten the screws.
3. Insert the two screws into the two bottom mounting holes and tighten the screws to secure them to the cabinet.
Figure 3.1 Cabinet Mounting Holes
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

The information in Section 4.3 and Section 4.4 pertains to the TR-MINIMON - Mini Monitor Module.
4.3.1 Wiring SLC Devices in (Class B) Configuration
There is no special wire required for the addressable loops. The wire can be untwisted, unshielded, solid or stranded as long as
it complies with the National Electric Code 760-51 Requirements for Power-Limited Fire Protective Signaling Cables. Wire
distances are computed using copper wire.
• The maximum wiring resistance is 40 ohms to the farthest SLC device.
• The maximum loop length depends on the wire gauge. See Table 4.2.
Figure 4.1 and Figure 4.2 show how the length is calculated when you use the Out and the Back Tap T-Tap style wiring.
.
Figure 4.1 Calculating the Wire Run Length for a Simple Out and Back
When you use the T-taps, the following are required:
• The total length of all taps and the main bus must not exceed 40,000 feet.
• Use the maximum distance requirements for the various wire gauges.
