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 this manual is read and understood.

CAUTION - 

System Reacceptance Test after Software

Changes:

 To ensure proper system operation, this product

must be tested in accordance with NFPA 72-1993 Chapter

7 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 be tested and proper

system operation verified.

This system  

meets NFPA requirements for

operation at 0-49

 and at a relative

humidity of 85% RH (non-condensing) at 30

C/86

O

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 nominal room temperature of 15-

27

O

 C/60-80

O

 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 interferences, proper

grounding will reduce susceptibility.  

Overhead or outside

aerial wiring is not recommended, due to an increased suscep-

tibility to nearby lightning strikes.  

Consult with the Technical

Services Department if any problems are anticipated or en-

countered.

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, and 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 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.

Audible warning devices

 such as bells 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.

A fire alarm system

 will not operate without any electrical

power.  If AC power fails, the system will operate from

standby batteries only for a specified time.

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.

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, how-

ever, 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 sched-

uled monthly or as required by National and/or local fire codes.

Adequate written records of all inspections should be kept.

An automatic fire alarm system

 - typically made up of smoke

detectors, heat detectors, manual pull stations, audible warn-

ing devices, and a fire alarm control with remote notification

capability can provide early warning of a developing fire.  Such

a system, however, does not assure protection against prop-

erty damage or loss of life resulting from a fire.

Any fire alarm system

 may fail for a variety of reasons:

Smoke detectors

 may not sense fire where smoke cannot

reach the detectors such as in chimneys, in walls, or 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.  Furthermore, all types of smoke detectors

- both ionization and photoelectric types, have sensing limi-

tations.  No type of smoke detector can sense every kind of

fire caused by carelessness and safety hazards like smoking

in bed, violent explosions, escaping gas, improper storage of

flammable materials, overloaded electrical circuits, children

playing with matches, or arson.

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, crippling its ability to report a fire.

While installing a fire alarm system may make lower insur-

ance rates possible, it is not a substitute for fire insurance!
