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 (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 first­floor 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

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. 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 . 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.

WARNING: High Voltages Present!

Use extreme caution when working with the AMPS-24. High voltage and AC line-connected circuits are
present in this power supply. Turn off and remove all power sources. To reduce the risk of electric shock,
make sure to properly ground the AMPS-24.
Install the snap-on cover for TB1 after wiring.

NOTE: A surge suppressor, model EDCO HSP121BT-1RU (for 120VAC operations) is required when using the
FCM-1-REL for releasing applications. The AMPS-24E power supply is not suitable for releasing applications.

NOTE: Test wire to wire faults with 0 ohm impedance.
