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 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 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 of 85% RH (non-condensing) at 30O C/86O 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 15-27O C/60-80
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 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, 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.
O
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.
Fire Alarm System Limitations
An automatic fire alarm system - typically made up of smoke detectors, heat
detectors, manual pull stations, audible warning 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 property 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. Further-
more, all types of smoke detectors - both ionization and photoelectric types, have
sensing limitations. 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 insurance
rates possible, it is not a substitute for fire insurance!
FCC Warning
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, however, 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 scheduled monthly or as required
by National and/or local fire codes. Adequate written records of all inspections should
be kept.
WARNING: This equipment generates, uses, and can radiate radio frequency
energy and if not installed and used in accordance with the instruction manual, may
cause interference to radio communications. It has been tested and found to comply
with the limits for class A computing device pursuant to Subpart B of Part 15 of FCC
Rules, which is designed to provide reasonable protection against such interference
when operated in a commercial environment. Operation of this equipment in a
residential area is likely to cause interference, in which case the user will be required
to correct the interference at his own expense.

Section Five:
Periodic Testing And Maintenance
To ensure proper and reliable operation, it is recommended that system inspection and testing be scheduled
monthly or as required by national and/or local fire codes. Testing should be done by a qualified services
representative if a malfunction is encountered.
Before testing:
1) Notify the fire department and/or central alarm receiving station if an alarm condition is transmitted.
2) Notify facility personnel of a test so that alarm sounding devices are ignored during the test period.
3) When necessary, activation of Notification Appliances can be prevented by pressing the DISABLE
switch.
Testing:
1) Activate a zone via an alarm initiating device and check that active Notification Appliances sound and
alarm LED lights. Reset system. Repeat for each zone.
2) Momentarily activate the following switches (one at a time) and check for a trouble signal:
• RESET
• DISABLE
3) Depress the TROUBLE SILENCE switch and check for an intermittent audible signal. Return TROUBLE SILENCE switch to normal position.
4) Momentarily open the following circuits one at a time and check for a trouble signal:
• Notification Appliance (bell) Circuit.
• Initiating Zone 1.
• Initiating Zone 2 (if employed).
5) If new batteries were installed, wait 48 hours before completing this step. Remove AC power, activate
zone and check that :
• the ALARM indicator lights.
• all active Notification Appliances sound.
Measure battery voltage while the Notification Appliances are sounding. Replace any battery with
terminal voltage less than 85% of rating. Reapply AC power and press RESET.
6) Return all switches to their normal outward positions. Notify fire department, central station and/or
building personnel that test is complete.

Section Six:
Troubleshooting Guide
Detailed acceptance testing procedures are beyond the scope of this manual. Such procedures must be
developed as part of the overall system installation. In each case, before the system is accepted into
service, it must meet the operating criteria established by the specifying engineer and endorsed by the
Authority Having Jurisdiction. Following is a checklist to aid in establishing operating criteria.
When full power is applied:
• The green power LED glows. No RED or YELLOW LEDs are on and no audible devices are sounding.
When an alarm is present:
• All activated alarm devices sound.
• The red alarm LED glows and the built-in audible device sounds steady.
When a trouble is present:
• The system trouble LED glows and the built-in audible device sounds while pulsing.
Troubleshooting Tips
• Don't panic. Calmly evaluate the symptoms.
• If more than one trouble is indicated, select a specific indication and troubleshoot it. It is better to
follow a logical sequence and not introduce any new problems.
• Prior to installation, check a new panel on the bench with ELRs whenever possible.
• On the job-site, determine as soon as possible if the problem is internal to the panel or in the external
circuits.
• Spare components (known to be good) are essential to fast, efficient troubleshooting.
• Follow the step by step procedures listed in this guide. Replacing components in a random manner
may cause additional damage to the system. Troubleshoot the component which has the trouble
indication and replace the component with a known good component.
• Always use voltage measurements when troubleshooting the panel.
• If you are unable to locate the problem by following these procedures, technical service is available
from the Fire•Lite Technical Services Department.
