1.4 TERMS USED IN THIS MANUAL
The following are various terms used in this manual with a brief description of each.
- Symbol for “ohm”. Unit of resistance.
Abort State – (“Abort” Yellow LED ON, Piezo pulsing). The Abort occurs when an input circuit configured for abort
operation has been activated while an alarm condition is present. The abort state is a non-latching event and is intended
for preventing a suppression zone from advancing to the release state.
AC Normal State - (“AC Normal” Green LED ON). The system is in the AC Normal state when appropriate AC power is
being applied to the system.
Alarm State - (“Alarm” Red LED ON, Piezo pulsing). The alarm occurs when an input circuit configured for alarm
operation has been activated. Activation typically initiated by a detector or contact device. The alarm state is a latching
event in the Cheetah Xi. The operator will be required to RESET the Cheetah Xi in order for the panel to exit/clear the
alarm state.
Class A Wiring – Initiating device circuit or notification appliance circuit that provides a redundant path and is capable of
transmitting an alarm signal past a single open. Conditions that affect the intended operation of the circuit are
annunciated.
Class X Wiring – Initiating device circuit or notification appliance circuit that provides a redundant path and is capable of
transmitting an alarm signal past a single open or short-circuit. Conditions that affect the intended operation of the circuit
are annunciated.
Class B Wiring – Initiating device circuit or notification appliance circuit that does not include a redundant path and where
operational capability stops at a single open. Condition that affect the intended operation of the circuit are annunciated.
Initiating Device - A system component that originates transmission of a change-of-state condition, suc h as in a smok e
detector, manual fire alarm box, or supervisory switch. This manual interchanges the terms initiating device and input
device.
Initiating Device Circuit A circuit to which automatic or manual initiating devices are connected where the signal
received does not identify the individual device operated. This manual interchanges the terms initiating device circuit and
input circuit.
Normal State - (“Trouble” Yellow LED OFF). The system is in the normal state when the power supply and all circuits are
configured properly, connected, and responding properly. The system remains in normal state until a trouble condition
occurs.
Notification Appliance - A fire alarm system component such as a bell, horn, speaker, light, or textual display that
provides audible, tactile, or visible output, or any combination thereof. The device notifies building occupants of system
status. This manual interchanges the terms notification and audible applian ce.
Notification Appliance Circuit - A circuit or path directly connected to a notification appliance(s). This manual
interchanges the terms notification appliance circuit and audible circuit.
Non-power-Limited - A circuit designation given for wiring purposes. The amount of current flowing through the circuit is
unlimited vs. being limited, or power-limited. AC power and Battery wiring is non-power-limited.
Power-Limited - A circuit designation given for wiring purposes. The amount of current flowing through the circuit is
limited (typically by fuse) vs. being unlimited, or non-power-limited. The Cheetah Xi addressable loops and output circuits
are power-limited. The circuit has a maximum power that flows through it or it current limits and opens the circuit.
Pre-Discharge State – (“Pre-Discharge” Red LED ON, Piezo pulsing). Pre-Discharge occurs when an input circuit
configured for alarm operation has been activated and the Suppression Pre-Discharge type is satisfied. The PreDischarge state is a latching event in the Cheetah Xi 50. The operator will be required to RESET the panel in order for
the panel to exit/clear the release state.
Release State – (“Release” Red LED ON, Piezo pulsing). Release occurs when an input circuit configured for manual
release operation has been activated or the Pre-Discharge automatic countdown has expired with no Abort input active.
The release state is a latching event and will follow the status of the supervisory input contact.
Supervisory State - (“Supervisory” Yellow LED ON, Piezo Warble). The supervisory state occurs upon activation of a
supervisory input circuit. The supervi sory state is non-latching and will follow the status of the supervisory input contact.
Trouble State - (“Trouble” Yellow LED ON, Piezo Constant). The trouble state occurs upon any detectable condition
which could impair system operation including connection problems, ground faults, hardware problems, power problems,
or configuration problems. Certain trouble conditions are latching; others allow the system to reset upon trouble condition
removal. Depending upon the type of trouble condition, the system may or may not remain operational. When the system
is in trouble state, it is not in the normal state.

2.1 SYSTEM DESCRIPTION
The Fike Cheetah Xi 50 (P/N 10-071) is a state of the art, true addr essable peer-to-peer fire suppression
control system. It provi des the latest techno logy in detection com munication with extensi ve programmabilit y
in one cost effective s ystem. Its intelligenc e has every device c ommunicating as a peer on the sign aling line
circuit. This intelligenc e provides speed with respons e times as little as o ne-qua rter sec ond between m anual
pull station activation to notification appliance sounding.
Its flexibility provides you the freedom to attach the devices you require for your specific installation. The
Cheetah Xi 50 is equipped with one signaling line circuit capable of communicating with 50 addressable
devices in any combination.

The Cheetah Xi 50 system includes the equipment
enclosure, control board, power transformer, and
necessary mounting hardware. Components such as
the cab inet color, transformer power requirements, and
cabinet requirem ents are custom configured to suit your
specific project requirements. Exhibit 3-2 shows the

3.2 CHEETAH Xi 50 CONTROLLER
The heart of the Cheetah Xi 50 system is the controller
(See Exhibit 3-3). The system controller consists of a
printed circuit board (PC B) that incorporates the s ystem
primary power supply with battery charger, system
microprocessors, hardware interface terminals, system
display and operational switches. The controller is the
central hub for communication between the systems
intelligent, addressab le field devices that are connect ed
to the panel’s signaling line circuits. The controller is
also used for system timing, user interface, power
delivery and system history archive.

3.2.1 NAC CIRCUIT LIMITATIONS
The NAC circ uit field wiring resis tance is limited by the amount of anticipated load. Many local authorities
require a voltage drop ca lculation be performed to de monstrate the lo west voltage pr esent at the las t device.
The designer shall determine the resistance of the wire specified and distance for the installation needs.
From this information, they can determine the total resistance for the circuit. Exhibit 3-8 provides the
maximum field wiring resistance for total device current that can also be used as a tool.

3.2.2 CONTROLLER TEST POINTS/VOLTAGES
The Cheetah Xi 50 controller has two primary test points . While viewing the panel disp lay, TP1 is located in
the lower right corner of the board t o the r ight of the boar d part num ber . TP2 is lo cated jus t to the r ight of the
relay block in the upper left corner of the board and is labeled 24V.
TP1 = COM
This test point should be used when making DC vo ltage measurements on the c ontrol board. Connect the
voltmeter ground lead to thi s point, a nd the n touc h the positive lead to the point under tes t. T his is the gr ound
reference for all points on the control board.
TP2 = 24V
This test point is the + side for the main controller 24VDC power buss. If the system does not seem to
operate properly even with AC power applied, connect the voltmeter positive lead to this point , and then
touch the ground lead to test point TP1 to verify the board voltage.
Ground Fault, TP1 to Chassis
With a normal pan el and no ground fault, this voltage is 2.17 VDC nom inal for Level 1 ground fault, and 5
VDC nominal for Level 2 ground f ault. If a ground fault is present, this voltage w ill sway in either direction.
Ground fault detection impedances are 60K ohm between power ground and chassis ground or 1M ohm
between main power and chassis ground.
