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
O
C/32-120
O
F
and at a relative
humidity of 85% RH (non-condensing) at 30
O
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!
