Fire-Lite PS Tools MS-9600 - Manual (Page 3)

A fire alarm system does not operate without
any electrical power. If AC power fails, the
system operates from standby batteries only for a
specified time and only if the batteries are
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 premise 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 fire alarm
malfunction is inadequate maintenance. To keep the entire fire alarm system in excellent working
order, ongoing maintenance is required per the
manufacturer's recommendations, and UL and
NFPA standards.
At a minimum, the requirements of NFPA 72 shall
be followed. Environments with large amounts of
dust, dirt or high air velocity require more
frequent maintenance. A maintenance agreement
must be arranged through the local
manufacturer's representative. Maintenance must
be scheduled monthly or as required by National
and/or local fire codes and must be performed
only by authorized professional fire alarm
installers only. Adequate written records of all
inspections must be kept.
Installation Precautions
Adherence to the following helps 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 Reacceptance 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 0-49ºC/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
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 the lightning induced
transients. Although no system is completely
immune from lightning transients and
interference, proper grounding reduces
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 do not interfere with
battery, transformer, 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 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.
