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 National Fire Protection Association
Standard 72 (NFPA 72), 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
that smoke 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 not sense 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, and
Authorities Having Jurisdiction (AHJ).
• Language and instructional requirements must be clearly disseminated on any local displays.
• Strobes can, under certain circumstances, cause seizures in
people 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 different 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 standby
batteries 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.
Telephone lines needed to transmit alarm signals from a premises to a central monitoring station may be out of service or temporarily disabled. For added protection against telephone line
failure, backup radio transmission systems 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 monthly or as
required by National and/or local fire codes and should be performed by authorized professional life saftety system installers
only. Adequate written records of all inspections should be kept.
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. Reacceptance 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 (noncondensing) 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 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.
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,
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. Overtightening 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 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 operation and reliability depend upon proper installation.

The following table provides a list of document sources (manuals) containing additional information regarding the
fire alarm control panels and components that ACS annunciators can be connected to. The FireLite document (DOCFIR) chart provides the current document revision.
The LCD-80FC Indicator is a compact, 80-character, backlit LCD fire indicator designed for use
with compatible FACPs (Fire Alarm Control Panels). It should be noted that the LCD-80FC Indi-
cator display will mimic the FACP display.
The LCD-80FC is capable of displaying English-language text of system point status including
device type, independent point alarm, trouble or supervisory, zone and custom alpha labels programmed into the control panel. The LCD-80FC also provides system status LEDs to display
Power, Alarm, Trouble, Supervisory and Alarm Silenced conditions. The LCD-80FC is capable of
performing local silence and local lamp test.
Communication between the FACP and the LCD-80FC is accomplished over a two-wire serial
interface employing the EIA-485 communication standard. Up to 32 indicators may be connected
to the two-wire EIA-485 circuit. The indicators may be powered from the host FACP or remote UL
listed, filtered, power supplies.

Figure 2.2 DIP Switch Settings Example
• One Indicator - if a single LCD-80FC is the only indicator connected to the EIA-485 loop,
Switch 3 must be set to the ON position to allow the FACP to supervise the indicator.
• Multiple Indicators - if multiple LCD-80FC indicators are connected to the EIA-485 loop,
the indicator physically connected as the last device on the loop (farthest from the ‘OUT’
terminals on the FACP) must have Switch 3 set to the ON position in order to supervise all
indicators on the loop. All remaining indicators must have Switch 3 set to the OFF position
for proper supervision and operation.
It is important to note that the function switches on all LCD-80FC indicators will operate regardless
of the setting of Switch 3.
A break (open circuit) in the power or EIA-485 connections creates an LCD-80FC Indicator fault at
the control panel. All indicators before the break will continue to display information (but the func-tion switches on these LCD-80FCs will no longer operate).
