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 notifi-

cation 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 commu-

nication, and other various interoperable communication meth-

ods—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 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, chim-

neys, 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 reach-

ing the detector.

The amount of “smoke” present may be insufficient to alarm

smoke detectors. Smoke detectors are designed to alarm at var-

ious levels of smoke density. If such density levels are not cre-

ated 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 cham-

bers 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 warn-

ing 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 materi-

als, 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 detec-

tors 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 devel-

oping fire may damage the alarm system, compromising its abil-

ity 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 intelligi-

bility requirements as defined by NFPA, local codes, and

Authorities Having Jurisdiction (AHJ).

• Language and instructional requirements must be clearly dis-

seminated 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 sig-

nals.

• 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 compat-

ible 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 prem-

ises to a central monitoring station may be out of service or tem-

porarily 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 stan-

dards. At a minimum, the requirements of NFPA 72 shall be fol-

lowed. 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 per-

formed by authorized professional life safety system installers

only. Adequate written records of all inspections should be kept.

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 associ-

ated equipment may be damaged by removing and/or insert-

ing 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 pro-

gramming 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 compo-

nents, 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 com-

ponents 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 indi-

cating 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 light-

ning 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 Ser-

vices Department if any problems are anticipated or encoun-

tered.

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 modifi-

cations, verify that they will not interfere with battery, trans-

former, 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 han-

dling 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 pro-

gramming manuals. These instructions must be followed to

avoid damage to the control panel and associated equipment.

FACP operation and reliability depend upon proper installation.

1.1.2 Mounting the Cabinet

Carefully unpack the system and check for shipping damage. Mount the cabinet in a clean, dry,

vibration-free area where extreme temperatures are not encountered. The area should be readily

accessible with sufficient room to easily install and maintain the panel. Locate the top of the cabi-

net approximately five feet above the floor with the hinge mounting on the left. Determine the

number of conductors required for the devices to be installed. Sufficient knockouts are provided

for wiring convenience. Select the appropriate knockout(s) and pull the required conductors into

the box. Note that knockouts are also located on the back of the cabinet. All wiring should be in

accordance with the National and/or Local codes for fire alarm systems.

The cabinet can be surface or flush-mounted. For flush-mount installation of the cabinet, the hole

for the enclosure should be 14.5" W x 24.75" H x 3.438" D (36.8cm W x 62.9cm H x 8.73cm D).

Do not flush-mount in a wall designated as a fire break. The outside dimensions of the cabinet are

16" W x 26.25" H x 4.125" D (40.64cm W x 66.68cm H x 10.48cm D).

Follow these steps to properly mount the cabinet.

1. Mark and predrill holes for the top two backbox keyhole mounting bolts using the dimensions

shown.

2. Install two upper fasteners in the wall with the screw heads protruding.

3. Using the upper 'keyholes', mount the backbox over the two screws.

4. Mark and drill the lower two holes.

5. Install the remaining fasteners and tighten all fasteners to complete backbox mounting.

1.1.3 Wiring Specifications

To avoid induced noise (transfer of electrical energy from one wire to another), keep input wiring

isolated from high-current output and power wiring. Avoid pulling one multiconductor cable for

the entire panel. Power-limited, nonpower-limited, and audio circuit wiring must remain separated

in the cabinet. Maintain at least 0.25” (6.35 mm) spacing. Power-limited, nonpower-limited, and

audio circuit wiring must enter and exit the cabinet through different knockouts and/or conduits.

For the same reasons, wiring within the cabinet should be routed around the perimeter of the cabi-

net. It should not cross the printed circuit board where it could induce noise into the sensitive

microelectronics or pick up unwanted RF noise from the high speed circuits.

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 beads or by wrapping it around a ferrite toroid

core. Figure 1.3 provides an example.
