SAFETY SUMMARY
This entire manual must be read and understood before installation.
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 this 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 Re-acceptance Test after Re-Programming: To ensure proper system operation, this product must be
tested in accordance with FPA -72 Chapter 7 after any programming operation. Re-acceptance 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 and system operations 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 FPA requirements for operation at 32°-120°F (0 to 49°C) and at a relative humidity of 93% RH (non-condensing)
@ 100°F (36.5°C). However, the useful life of the systems 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 60-80°F.
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 interference, proper grounding will reduce suscep-
tibility. The use of overhead or outside aerial wiring is not recommended due to the increased susceptibility to nearby lightning
strikes. Consult with the Applications Engineering Department if any problems are anticipated or encountered.
Remove all electronic assemblies prior to any drilling, filing, reaming, or punching of the enclosure. When possible, make all cable
entries from the sides. Before making modifications, verify that they will not interfere with battery and printed circuit board location. Do
not over tighten screw terminals, 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 systemtypically 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. o type of smoke detector can sense every kind of fire caused by carelessness and safety hazards
such as smoking in bed, violent explosions, escaping gas, improper storage of flammable materials, overloaded electrical circuits,
children playing with matches, or arson.
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 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.

Auxiliary 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.
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 ational and/or local fire codes. Adequate written records of all inspections
should be kept.
GENERAL SAFETY NOTICES The following must be observed to maintain personnel safety.
The following general safety notices supplement specific warnings and cautions appearing in the manual. The safety precautions in
this section must be understood and applied during operation and maintenance. This manual is to be used by trained distributors/
technicians. The entire manual should be read and fully understood prior to installation.
CAUTION
!
- TEST EQUIPMENT
Make certain test equipment is in good operating condition. Do not touch live equipment or personnel working on live equipment
while holding a test meter. Some types of measuring devices should not be grounded; these devices should not be held when taking
measurements.
FIRST AID
Any injury, no matter how slight, should never go unattended. Always obtain first aid or medical attention immediately.
GENERAL PRECAUTIONS
The following general safety precautions are to be observed at all times:
1. All electrical components associated with equipment shall be installed and grounded in accordance with EC, FPA
and local regulation requirements.
2. Special precautionary measures are essential to prevent applying power to equipment at any time maintenance work is
in progress.
3. Before working on electrical equipment, use a voltmeter to ensure that system is not energized.
4. When working near electricity, do not use metal rules, flashlights, metallic pencils, or any other objects having exposed
conductive material.

Kidde Gemini II System
CHAPTER 1
GENERAL INFORMATION
1-1 INTRODUCTION
This manual contains installation, configuration and opera-
tion instructions for the Kidde Gemini II System.
1-2 SYSTEM DESCRIPTION
The Kidde Gemini II is a versatile fire alarm/suppression
control system which can be used in a wide range of appli-
cations from a minimal, stand-alone single-hazard to a
large, eight-hazard system with multiple display units. The
system is microprocessor-based to offer flexible, modular
fire alarm and hazard release for a wide variety of Class A
or B applications.
As a minimum, a one-hazard system is controlled by one
Main Control Panel. The system can be expanded by add-
ing up to seven Remote Hazard Units and up to 16 Remote
Display Units. An example UL system is shown in
Figure 1-1.
The Main Control Panel and each Remote Hazard Unit
controls its own releasing circuit. Each unit accepts inputs
from initiating (detecting) devices such as smoke detec-
tors, heat detectors, manual pull stations and waterflow
sensors. Based on pre-programmed instructions and your
own configuration parameters outputs are generated to
release agent or activate a sprinkler system, shutdown
equipment and annunciate alarms at the unit and external
panels. The agent release sequence can be interrupted from
an abort station which can be configured for one of four
abort modes.
The Main Control Panel monitors all units in the Kidde
Gemini II System and collects and displays system-wide
messages. A Remote Hazard Unit fitted with the optional
display can also display global (system wide) or local mes-
sages, depending on its configuration.
The Remote Display Unit does not itself monitor a hazard,
but displays messages and accepts manual release and
abort inputs which are then passed on to the Main Control
Panel or Remote Hazard Unit to which the Remote Display
Unit is assigned.
The units communicate over a RS-485 data highway which
is controlled and monitored by the Main Control Panel.
See Appendix F for special Canadian requirements.
1-3 HAZARD ANALYSIS
An analysis of the hazard to be protected must be performed
by a qualified fire protection specialist before the system
can be installed.
The following are some factors that must be considered in
determining the suitability of the Kidde Gemini II System
for each application.
What type of suppression system will be used?
The Kidde Gemini II System can provide actuation for
Halon, CO2, FM-200 and FE-13 clean agent systems,
the Kidde IND (Industrial Dry Chemical) System and
the WHDR Wet Chemical suppression system. The
system is also FM approved for Deluge & Pre-Action
Sprinkler Systems (see Paragraph 1-9 for more
information).
In what type of environment will the system be used?
The Kidde Gemini II System is suitable for use in con-
trolled environments, in a temperature range of 32°F
to 120°F (0°C to 49°C). The system must not be used
in hazardous locations, or Class I, II, or III atmospheres
as defined in NFPA Standard 70-500.
Is battery backup required?
The Kidde Gemini II System provides supervised bat-
tery backup within the enclosure. Backup batteries are
charged automatically and switch-over is automatic in
the event of power failure or brownout.
Is flexible discharge sequencing and control required?
The Kidde Gemini II System provides flexible, field-pro-
grammable control over the actuation and annuncia-
tion process. The system operation can be tailored in
the field using display panel and manual control but-
tons. Programming can be easily field-modified if re-
quirements change.
Is expandability a concern?
The Kidde Gemini II System provides for modular ex-
pansion of both monitor and actuation circuits. Adding
Remote Hazard and Remote Display Units is fast and
simple. The system can contain up to seven Remote
Hazard Units and up to 16 Remote Display Units.
1-4 MAIN CONTROL PANEL
The Main Control Panel (Figure 1-2) controls one hazard
block. It accepts inputs from initiating (detecting) devices
such as smoke detectors, heat detectors, manual pull sta-
tions, supervisory (diagnostic) circuits and waterflow sen-

sors. Based on pre-programmed instructions, and your own
configuration parameters, outputs are generated to release
agent or activate a sprinkler system, shutdown equipment
and annunciate an alarm.
All alarms, troubles and supervisory signals received at the
panel are logged and displayed for the operator. While not
every alarm results in an agent release, those that do are
called decisive alarms. The conditions under which a deci-
sive alarm occursand what happens afterwardsare de-
scribed in Paragraph 3-2, Agent Releasing Logic.
1-4.1 Display Panel
The front of the Main Control Panel contains five LEDs and
a 4 line x 20 character display window for text messages.
See Paragraph 2-2 for information on operating the display
panel.
A buzzer provides an audible warning of a system alarm or
trouble. It sounds continuously when a new alarm or trouble
is detected and can be silenced with the SILENCE button.
Scroll buttons are provided to view current alarm, supervi-
sory and trouble messages.
The RESET button removes power from the initiating cir-
cuits, thereby resetting the detectors.
Arrow keys provide access to the menu system where con-
figuration parameters for the Main Control Panel and all
other remote units may be entered and reviewed.

Kidde Gemini II System
1-4.2 Power Supply and Battery Backup
The power supply operates from either 120 Vac 50/60 Hz
or 240 Vac 50/60 Hz. Besides powering the system, the
power supply also charges a standby battery set which pro-
vides backup in case of loss of power from the AC source.
While the battery charger is capable of charging batteries
of capacity from 12 to 66 AH at 24 Vdc, the actual battery
capacity used for an application is a function of the panels
components, devices and configuration. Please see Appen-
dix A for more details on how to perform battery capacity
calculations.
The power supply includes two auxiliary 24 Vdc power out-
puts; one is resettable and the other non-resettable. The
non-resettable auxiliary power supply can be used to pro-
vide power to the Remote Display Units as described in
Paragraph 1-6.2.

Figure 1-3. Input and Output: Main Control Panel and Remote Hazard Unit
The power supply monitoring circuit provides a trouble sig-
nal if any of the following conditions occur:
Loss of AC input or if AC power falls below 85% of
nominal. This causes an immediate change-over to
battery operation and a trouble signal after 30 seconds.
Detection of a ground fault.
Charger output trouble in the charger circuit.
The battery circuit is monitored and a trouble message re-
sults under the following conditions:
The battery is faulty or it was installed backwards.
The battery is disconnected.
Battery voltage falls below 18.6 V (this condition causes
the battery to disconnect and can only be cleared when
primary AC main power is restored).
1-4.3 Hazard Block Inputs
Inputs and outputs for the Main Control are shown in Fig-
ure 1-3 and summarized below.
firealarmresources.com

1-406-235975-001 November 2002
Kidde Gemini II System
1-4.3.1 INITIATING CIRCUITS 1 AND 2
Two detecting circuits are provided; each can power and
supervise up to 40 conventional Fenwal point-type smoke
detectors and normally open contact closure devices. The
number of contact closure devices is limited only by the
total line resistance allowed. Both circuits can be reset with
the RESET button on the front of the Main Control Panel
which removes power for at least one second to allow the
detectors to reset.
1-4.3.2 WATERFLOW CIRCUIT
The waterflow circuit accepts input from and provides
power to an external waterflow sensor which indicates that
a fire-activated sprinkler nozzle has been activated.
1-4.3.3 SUPERVISORY INPUT (SUPV 1)
The Supervisory Circuit is used to accept inputs from moni-
toring devices such as Agent pressure switches on Agent
Cylinders or water pressure switches on Sprinkler Systems.
For systems where two supervisory inputs are required,
the Abort Circuit, described in Paragraph 1-4.3.5, may be
configured as a second Supervisory input.
1-4.3.4 MANUAL RELEASE INPUT
An input signal from a manual release switch starts the
manual release sequence. After the specified time delay,
agent release output and indicating circuits are activated.
1-4.3.5 ABORT/SUPV 2 INPUT CIRCUIT
A signal from the abort switch starts the abort sequence,
which delays or cancels agent release (see Paragraph 3-3
for more on Abort).
For systems in which the Abort circuit is unutilized, it may
be configured as a second Supervisory Circuit. When con-
figured as a Supervisory circuit, this circuit operates in ex-
actly the same manner as the Supervisory Circuit described
in Paragraph 1-4.3.3.
1-4.4 Hazard Block Outputs
1-4.4.1 RELEASE OUTPUT CIRCUIT
The release output circuit controls the release of a fire sup-
pressing gas and/or activates a Deluge/Pre-Action system.
The release output is supervised for open circuit and can
drive either:
(a) One or two ganged Kidde Solenoid Control Head P/Ns
890181, 899175, 48650001 or 81-100000-001, or
(b) One or two ganged Kidde solenoid Control Head P/Ns
890181, 899175, 48650001 or 81-100000-001 plus one
Stop/Directional Valve Control Head for Systems using
Clustered Agent Cylinders (a common cylinder bank
protects multiple hazards and Stop Valves direct Agent
to the affected area), or
(c) One Factory Mutual Group A, B, D, E or G Deluge/Pre-
Action solenoids or,
(d) One Kidde solenoid Control Head P/N 890181, 899175,
48650001 or 81-100000-001 in conjunction with one
FM Group A, B, D, E or G solenoid for operation of a
Clean Agent Suppression system along with a Deluge/
Pre-Action System.
The release circuit may be programmed for a solenoid ON
time of 90 seconds for Kidde Control Heads and either 10
minutes, 15 minutes or On-until-reset for Deluge/Pre-Ac-
tion Solenoids.
1-4.4.2 RELAY OUTPUT (MCP ONLY)
Three Form C primary relay output circuits can be used to
control building functions such or shutdown power during a
fire.
1. Alarm Relay:
Normally de-energized. This relay is energized when
any alarm, a manual pull or waterflow event occurs any-
where in the system. Once activated it is latched until
the system is reset.
2. Trouble relay:
Normally energized. This relay is de-energized when-
ever a Trouble (not supervisory) alarm occurs anywhere
in the system. This relay is momentary; when the trouble
is resolved, the relay is energized again.
3. Programmable relay:
Normally de-energized. This relay can be programmed
to activate and latch on the occurrence of one of the
following conditions anywhere in the System:
(a) A global 1ST Alarm condition.
(b) A global Pre-Discharge condition.
(c) A global Discharge condition.
(d) A global Manual Release Input.
(e) A global Waterflow Input.
(f) A global Abort Input.
(g) A global Supervisory Input.
(h) A global Trouble event.
For contact ratings of all three relays, see Tables 1-1, 1-2
and 1-3.
1-4.4.3 OPTIONAL RELAY BOARD (ORB)
A socket is provided in the Main Control Panel and Remote
Hazard Unit for an Optional Relay Board. ORBs have five
programmable Form C Relays, each of which can be con-
figured to respond to one of the following events occurring
local to the unit that the ORB is mounted on:
(a) A local 1ST Alarm condition.
(b) A local Pre-Discharge condition.
(c) A local Discharge condition.
(d) A local Manual Release Input.
(e) A local Waterflow Input.
firealarmresources.com

1-5November 2002 06-235975-001
Kidde Gemini II System
(f) A local Abort Input.
(g) A local Supervisory Input.
(h) A local Trouble event.
(i) No activation.
1-4.4.4 INDICATING CIRCUITS
Indicating Circuits 1 and 2 activate external audible and
visual indicating appliances. Both circuits operate inde-
pendently and can be programmed to operate on one or
more of the following conditions listed in order of priority
(low to high):
1
ST Alarm
Waterflow
Pre-Discharge
Manual Release
Discharge
The two circuits can be further configured to generate one
of the following tones to indicate the occurrence of the above
listed conditions:
Silent
Steady (Silenceable)
Steady (Non-Silenceable)
Pulse 60 (Silenceable)
Pulse 60 (Non-Silenceable)
Pulse 120 (Silenceable)
Pulse 120 (Non-Silenceable)
Temporal (Silenceable)
Temporal (Non-Silenceable)
In operation, the Indicating Circuits will change accordingly
as the Alarm and subsequent discharge status progresses.
Notes:
1. A given Alarm condition cannot be programmed to be
Silent on both Indicating Circuits.
2. A Manual Release creates either a Pre-Discharge or
Discharge condition. If it creates a Pre-Discharge con-
dition, i.e., there is still a timeout period, the Manual
Release tone will override the Pre-Discharge Tone
whereas for a Discharge condition the Discharge Tone
will take precedence. The Manual Release Tone will
also take precedence if operated during the Pre-Dis-
charge condition created by the automatic detection
system.
3. While Waterflow inputs cannot be Silenceable, an In-
dicating Circuit may be set to be Silenceable for all other
Alarm states. Consequently, in a release where a
Waterflow is activated, for all subsequent states of the
release the Indicating Circuit will become Non-
Silenceable (even if any subsequent phases were pro-
grammed to be silent).
4. As required for all UL/Canadian applications, the Abort
Tone when set to ON may be independently assigned
to either or both Indicating Circuits.
1-4.5 Communications
The Main Control Panel controls communications with all
units in the system through an RS-485 network communi-
cation port.
1-4.6 Logs
The Main Control Panel keeps two logs: the Event Log and
a Configuration Log.
The Event Log in the Main Control Panel collects all event,
alarm and supervisory messages throughout the system.
When the Event Log reaches its maximum capacity of 270
events, a new message overwrites the oldest message.
The MCP uses its volatile memory to create a System Ac-
tive Event List. This list contains every active alarm, trouble
and supervisory event that is present on the system. These
include those events that have been created by the MCP
itself, those that have been created at an RHU and trans-
mitted to the MCP and those that have been created at an
RDU and transmitted to the MCP.
When any of these active events is silenced/acknowledged,
that fact is recorded in the System Active Event List. Events
are removed from the System Active Event List as the
events clear.
The MCP uses the contents of the System Active Event
List to control the information displayed by itself and the
RHUs and RDUs. In other words, new events are displayed
as they occur (new troubles and supervisory events are
not shown if there is an active alarm event).
After all new events have been shown, the priority event
will be shown. The priority event is decided in the following
ways:
IF: There are any devices (MCP or RHUs) in alarm, the
priority event is the first alarm event.
ELSE IF: There are any devices (MCP or RHUs) in
non-decisive alarm, the priority event is the alarm event
for the first device in alarm.
ELSE IF: There is any device (MCP or RHU) in walk
test, the priority event is the walk test condition.
ELSE IF: There are any devices (MCP or RHUs) with
supervisory events, the priority event is the first super-
visory event created.
ELSE IF: There are any devices (MCP or RHUs) with
trouble events, the priority event is the first trouble event
created.
The MCP uses its non-volatile memory to provide a Sys-
tem Event Log. This is a log of events occurring at the MCP
and all RHUs and RDUs. It records the time and date of
the following:
firealarmresources.com

1-606-235975-001 November 2002
Kidde Gemini II System
When events (alarms, troubles or supervisory) occur/
become active
When events clear
When events are silenced/acknowledged
When the MCP/RHUs or RDUs are reset
When the Abort is activated
When the MCP and/or RHU releases its agent.
As mentioned earlier, current alarms and supervisory mes-
sages are viewed by pressing the ALARM SCROLL and
SUP/TBL (Supervisory/Trouble) SCROLL buttons. Once
the events clear and are no longer in alarm, you can see
the messages by selecting event log from List in the menu
system. The log contains two messages for the same event;
one message is generated when the event occurred and
the other message is generated when the condition cleared.
Viewing Lists is described in Paragraph 2-9.
The configuration log in the Main Control Panel stores con-
figuration parameters that you entered through the menu
system. Current and past configuration parameters can be
viewed through the menu system. See Paragraph 2-9 for
instructions.
1-4.7 Printed Circuit Boards
The Main Control Panel is microprocessor-based and con-
tains Flash EPROM and RAM memory as well as non-vola-
tile memory to store the Event Log and system configuration
parameters. This means these parameters are saved even
when the unit is powered down. Battery backup also pow-
ers the real-time clock in the Main Control Panel if needed.
The real-time clock is used to time stamp all messages
throughout the system.
1-4.8 Enclosures
All enclosures are NEMA Type 1. They are intended to be
used indoors in a relatively dust-free environment. The en-
closures are equipped with hinged doors that swing open
180° for accessibility.
The Main Control Panel enclosure is 18 gauge steel painted
red. A steel door is held closed by a key lock. All operator
interface switches and indicators are located behind the
locked cover. The enclosure is large enough to house two
12 Vdc, 12 AH batteries required for standby operation.
An optional dead-front enclosure is available (mandatory
in Canada). The dead front protects the user from any ex-
posed wiring. There is a hole in the front of the enclosure
which allows you access to the ALARM SCROLL and SUP/
TBL (Supervisory/Trouble) SCROLL buttons without open-
ing the door.
See Appendix F for special Canadian requirements.
1-5 REMOTE HAZARD UNIT
The Kidde Gemini II system can be expanded to include up
to seven Remote Hazard Units.
The Remote Hazard Unit is programmed from the Main
Control Panel and can be configured for global or local
operation (more on this below). Values are stored in non-
volatile (permanent) memory in the Remote Hazard Unit.
The Remote Hazard Unit communicates with the Main
Control Panel over the data network.
1-5.1 Power Supply and Battery Backup
The power supply operates from either 120 Vac 50/60 Hz
or 240 Vac 50/60 Hz. Besides powering the system, the
power supply also charges a standby battery set which pro-
vides backup in case of loss of power from the AC.
While the battery charger is capable of charging batteries
of capacity from 12 to 66 AH at 24 Vdc, the actual battery
capacity used for an application is a function of the panels
components, devices and configuration. Please refer to
Appendix A, Battery Capacity Calculations, for more de-
tails on how to preform these calculations.
The power supply includes two Auxiliary 24 Vdc power out-
puts; one is resettable and the other non-resettable. The
non-resettable Auxiliary power supply can be used to pro-
vide power to the Remote Display Units as described in
Paragraph 1-6.2.
The power supply provides a trouble signal if any of the
following conditions occur:
Loss of AC input or if AC power falls below 85% of
nominal. This causes an immediate change-over to
battery operation and a trouble signal after 30 seconds.
Detection of a ground fault.
Charger output trouble in the charger circuit.
The battery circuit is monitored and a trouble message re-
sults under the following conditions:
The battery is faulty or it was installed backwards.
The battery is disconnected.
Battery voltage falls below 18.6 V (this condition causes
the battery to disconnect and can only be cleared when
primary AC main power is restored).
1-5.2 Display
The optional display panel on the Remote Hazard Unit con-
tains five system status LEDs, a display panel for trouble
and alarm messages, and control buttons to silence the
alarm buzzer and scroll through alarm and event data. The
DISPLAY and SILENCE buttons operate in local or global
mode. The RESET button is local only.
