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.
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 0-49OC/32-120OF
and at a relative humidity of 85% RH (non-condensing) at 30O C/86OF.
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 15-27OC/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 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.
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
While installing a fire alarm system may make lower insurance
rates possible, it is not a substitute for fire 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
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.
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.
