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 sitespecific 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
humidity of 85% RH (non-condensing) at 30O C/86
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 1527O C/60-80O F.
O
C/32-120O F and at a relative
O
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.
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.
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. Furthermore, 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!
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.

Section One: Annunciators
Fire•Lite annunciator modules provide the Sensiscan 2000 with up to 32 remote serially
connected annunciators, each with a capacity of 64 points.
The annunciator modules provide arrays of LEDs to indicate, at a remote location, the
status of circuits within the system. Annunciator points in a Sensiscan 2000 directly follow
the circuit arrangement of modules installed in the cabinet.
Control of common system functions such as signal silence, system reset, and local
annunciation controls (local acknowledge and lamp test) may be accomplished through
the annunciator's integral membrane push switches.
Communication between the FACP and the annunciators is accomplished over a powerlimited two-wire serial interface employing an EIA-485 communication standard. Power
is provided via a separate power-limited power loop from the control panel which is
inherently supervised by the FACP (loss of power results in an annunciator communication failure at the control panel). The annunciator can also be powered from a remote UL
listed power-limited power supply.
There are two basic annunciator types, alarm and alarm/trouble, each with its own
expander module.

Section Three:
Design Considerations
Limits
Up to 32 annunciators may be installed on an EIA-485 circuit. The actual number of
annunciator modules may be larger depending on the number of expander modules
employed.
Wire Runs
Communication between the Control Panel and the annunciator is accomplished over a
power-limited two-wire EIA-485 serial interface. This communication, including the
wiring, is supervised by the fire alarm control panel. Power for the annunciators is
provided via a separate power-limited power loop from the control panel which is
inherently supervised (loss of power also results in a communication failure at the control
panel).

Wiring Specifications
The EIA-485 circuit cannot be T-Tapped; it must be wired in a continuous fashion from
the control panel to the annunciator. The maximum wiring distance between the
panel and the last annunciator is 6,000 feet @ 16 AWG.
The wiring size must be a 14 AWG to 18 AWG twisted
shielded pair cable having a Characteristic Impedance of
120 ohms, +/- 20%. Limit the total wire resistance to 100 ohms on the EIA485 circuit, and 10 ohms on the annunciator power circuit. Do not run cable adjacent to,
or in the same conduit as, 120 volts AC service, noisy electrical circuits that are powering
mechanical bells or horns, audio circuits above 25 volts (RMS), motor control circuits, or
SCR power circuits. Twisted-shielded wiring should be used for EIA-485 circuits that are
not contained entirely in conduit.

Receive Only Annunciators
For redundant annunciation of system points, annunciators can be configured as
"Receive Only" annunciators. Receive Only annunciators are not fully supervisable.
Receive Only annunciators intercept information being transmitted to a "Receive/
Transmit" annunciator so that information can be duplicated at an intermediate display
location. When configured for Receive Only operation, they cannot send information to
the system, therefore they cannot perform remote functions such as Acknowledge,
Silence, or Reset. Control switches on Receive Only annunciators can be used only for
local functions, such as lamp test. Wiring to Receive Only annunciators may be
supervised by installing the modules "upstream" of fully-supervised Receive/Transmit
annunciators along the EIA-485 line.
Receive/Transmit Annunciators
Annunciators that are configured to serve as full function annunciators can both receive
status information as well as transmit commands to the control panel. This allows the
annunciator to remotely execute functions of the control panel in addition to displaying the
status of the system.
