DESCRIPTION
The Kidde Gemini II Multi-Hazard is the technologically
most advanced Conventional Suppression (agent releas-
ing) Control System available to the suppression industry
today. Employing distributed intelligence architecture, the
Kidde Gemini II system enables highly reliable monitoring
and suppression control for up to eight separate hazards.
The system consists of a master Main Control Panel
(MCP) which is a microprocessor based, field-config-
urable single hazard panel with a plethora of intelligent
features including LCD Display, digital Release Count-
down, password protected Menu System, Event History
Log, Configuration Log, Walk Test and Remote Battery
Test capability. As shown in Figure 1, this basic system
can be field-expanded to be a large eight hazard Control/
Display System with up to seven Remote Hazard Units
(RHU) and sixteen Remote Display Units (RDU), all of
which reside on a fault tolerant communications network.
The MCP and each RHU is intended to be physically
located in the space it is meant to protect. Since the MCP
and RHUs are computer-controlled, each one can act in
stand-alone mode in the event of damage to any of the
other panels. Under worst case fault conditions the only
protection threatened is within the space where the dam-
age occurred. All other protected areas continue to func-
tion normally. System reliability is substantially improved
since wiring for each protected space is only run a short
distance to the local panel.
Featuring a compact and aesthetically pleasing design,
the Gemini II is ideally suited for modern commercial,
high-tech and industrial applications. It is approved for
Kidde FM-200®, FE-13™ and CO2Clean Agent Systems
as well as Kidde IND™ Dry Chemical & WHDR™ Wet
Chemical Systems. The Gemini II is also listed for Sprin-
kler Supervisory Service and for Halon, Foam/Foam-
Water and Deluge/Pre-Action Systems.
MAIN CONTROL PANEL (MCP)
MCP POWER SUPPLY
The MCP operates on 120/240 Vac 50/60 Hz Power Sup-
ply. The Power Supply Unit is rated 4 Amps at 24 Vdc
and is provided with a Battery Charger to charge a 24
Vdc backup battery with a capacity 12 to 66 AH. The bat-
tery may be sized for 24 hour standby with 5 minutes
alarm or for 90 hour standby with 10 minutes alarm,
depending on the suppression system. The Power Sup-
ply is supervised and causes an immediate changeover
to battery in the event of loss of AC input or drop in input
voltage.

character alphanumeric LCD Display, status LEDs and
System Control and Menu Control buttons as shown in
Figure 2.

MCP CONSTRUCTION
The MCP enclosure is designed for surface mounting
and is rated NEMA 1 for indoor use. It is constructed of
18 Gauge steel, painted red and kept closed by a steel
door with a key-lock. All operator interface switches and
indicators are located behind the locked cover. The
enclosure is large enough to house two 12 AH 12 Vdc
batteries for backup power supply. Battery Enclosures
are available for larger capacity batteries. A trim-ring is
available for flush mounting.
REMOTE HAZARD UNIT (RHU)
RHU POWER SUPPLY
The Power Supply Unit in the RHU is the same unit as in
the Main Control Panel.
RHU DISPLAY-CONTROL MODULE
Remote Hazard Units are available either with or without
a Display-Control Module. When used, as shown in Fig-
ure 4, the RHU Display-Control Module is similar to that
of the MCP with the exception of the Menu Control but-
tons, which are provided only on the MCP. RHU Displays
can be programmed to operate either in local or global
mode.
Figure 4. RHU Display-Control Module
RHU INPUT AND OUTPUT CIRCUITS
Each RHU is also a Single Hazard Panel and is similar to
the Main Control Panel being provided with the same
Input and Output Circuits (with the exception of the three
System Relays). The Optional Relay Board (ORB) can
also be mounted to the RHU.
RHU CONSTRUCTION
When using the optional Display-Control Module, the

REMOTE DISPLAY UNIT (RDU)
RDU POWER SUPPLY
The RDU operates on 24 Vdc Power received from the
non-resettable Auxiliary 24 Vdc Power Output of the
MCP or associated RHU or any other UL Listed 24 Vdc
Power Supply Unit.
RDU DISPLAY-CONTROL MODULE
The RDU is a “display only” unit and can be programmed
to operate either in local or global mode. In local mode, it
mimics the Display of the MCP or the RHU to which it is
assigned. In global mode, it mimics the display of the
MCP. The RDU Display-Control Module provides a LCD
Display, one Power/Communication Status LED and Sys-
tem Controls as shown in Figure 5.
Figure 5. RDU Display-Control Module
RDU HAZARD BLOCK
RDUs do not control suppression systems, but optionally,
may be used to accept one Manual Release and one
Abort input from the local protected zone to which the
associated MCP or RHU is assigned.
RDU CONSTRUCTION
The RDU Backbox is constructed of 18 gauge steel,
painted beige and kept closed by the Display-Control
Module front plate. The front plate itself is constructed of
18 gauge steel and is painted red.
SPECIAL GEMINI II CONFIGURATIONS
As shown in Figure 6, due to special Canadian annuncia-
tion requirements, MCPs listed by ULC of Canada are
designed to be suitable for mounting one to three LED
Display Modules. Each LED Display Module pertains to
one zone of protection and provides 16 zone-specific
LEDs over and above the five System LEDs provided on
the MCP Display-Control Module. Enclosures of ULC
listed MCP and RHU units are provided dead-front pan-
els.

GEMINI II SYSTEM INTELLIGENCE
The Gemini II System allows operator access to its intelli-
gence via the Menu Control buttons on the Main Control
Panel. The Main Menu, which is enabled by pressing any
Menu Control Button (except Cancel) on the Main Con-
trol Panel (MCP), is structured per the architecture
shown in Figure 7. The Set, Isolate and Test functions
are password protected to limit access to authorized per-
sonnel only.
Figure 7. Menu Structure
The Set Function allows the operator to change pass-
word, set current date and time and the site-specific
operating configuration for the entire system. When the
System is initialized, the MCP downloads the operating
configuration to the RHUs and RDUs.
The List Function enables the operator to list the system
operating configuration, any isolated devices, registered
RHUs and RDUs and the Event History Log.
The Event History Log is a compilation of all Alarm,
Trouble, Supervisory and Event messages stored in non-
volatile memory. A maximum of 270 events can be stored
and the occurrence of a new event beyond the maximum
capacity erases the first. The Event Log can be cleared
by using the Gemini II ISP (In-Service Programming) Util-
ity CD-ROM.
The Isolate Function is used to isolate and de-isolate
input and output circuits on the MCP and all remote units.
The Test Function allows the operator to conduct a sys-
tem Walk test and Battery test on the MCP and all remote
units.
IN-SERVICE PROGRAMMING
The ISP Utility is a software program used to clear the
Event History Log of a Gemini II System and to upload
feature enhancements to its operating system. The ISP
Utility CD-ROM operates on IBM compatible computers
running Windows 95, 98, 2000, XP, ME or NT and is con-
nected to the ISP port on the MCP, RHU and RDU via
Kidde P/N 74-100016-003 PEGAsys™ Telephone Cable
with DB9 Adapter.
