Three-Height-Unit Backbox
The three-height-unit backbox is part
of the Cerberus PRO intelligent voice-
communication system hardware for
use with 3HU system enclosures.
Specifically, each backbox is used to
fasten with a 3HU outer door.
Each 3HU backbox can be ordered in
black (Model FHB2005-U1 or red
(Model FHB2005-R1).
Approximate size: 42" (106.7 cm.)
high; 21" (53.3 cm.) wide, and 7.75"
(19.7 cm.) deep.
S-Series License Keys
The S1 license key (Model FCA2033-A1) allows for virtual
monitoring and control between a Cerberus PRO IVC panel
and a personal computer. The S2 license key (Model
FCA2034-A1) is a BACnet output, and is used for
monitoring-only purposes by a 3rd-party system for life-
safety objects.
The S3 license key (Model FCA2035-A1) is a combination
license key that allows for virtual monitoring and control, as
well as for distribution of BACnet (monitoring-only)
communications.
Three-Height-Unit Outer Door
For each Model FV922 / FV924 FACP,
one (1) red or black backbox supports
one (1) equivalent red or black outer
door. Each three-height-unit outer door
contains three (3) horizontal openings
(in order for easy access to the system
operating unit), voice system card cage,
and battery brackets.
Clear Lens
The window (Model FHD2006-U1) is a rugged Lexan® lens
that can be mounted to any of the rectangular cut-outs
found on each Model FHD2007-series outer door.
Approximate size: 10.25" (26.04 cm.) high and 17" (43.2
cm.) wide.
Three-Height-Unit Blank Plate
Instead of using a Lexan clear lens, an installer has the
option of using a 3HU blank plate, Model FHD2009-U1,
which covers empty spaces in a given row of a 3HU
enclosure, (in place of any redundant operator interface
switch and / or microphone option module).
Three-Height-Unit Enclosure Trim Kit
This optional trim kit is used to provide a tidy appearance of
a 3HU enclosure when used in flush-mount applications.
Each trim kit can be purchased in either red (Model
FHA2043-R1) or black (Model FHA2043-U1), and comes
unassembled in four (4) slats.
Inner Doors
There are two (2) inner doors available for Cerberus PRO
system enclosures. The inner door, which is available
exclusively in black, specifically stores the Standard
Operating Unit, or the Operating Unit with LEDs.
Additionally, the Model FHD2004-U1 inner door supports
one (1) system operating unit, or one (1) to four (4) LED
option modules. When less than four (4) LED option
modules are used, the blank-option module (Model
FCM2022-U3) covers unused module spaces in the inner
door.
Approximate size: 13.25" (33.7 cm.) high and 20" (50.8
cm.) wide
Note: Model FHD2005-U1 is a solid-black, inner-door blank plate
used to provide dead-front protection
Modular Ethernet Switch
The Modular Ethernet Switch (Model
FN2012-A1) serves as a network connector
between Models FC922, FC924 and FT924
fire-only Cerberus PRO FACPs and with Model
FV922 / FV924 Cerberus PRO intelligent
voice-communication systems.
Panel-to-panel communication is transmitted
via CAT5, single-mode fiber or multi-mode
fiber. One (1) or two (2) Ethernet modules
are supported by each Modular Ethernet
Switch, which serves as a connector to:
▪ Model VN2001-A1 for CAT5 connection (or better)
▪ Model VN2002-A1 for multi-mode fiber connection
▪ Model VN2003-A1 for single-mode fiber connection
Model FN2012-A1 mounts in the backbox of one-height-
unit or two-height-unit enclosures, in place of a standard
fiber module.
Electric Ethernet Module
The Electric Ethernet Module (Model VN2001-A1) serves as
a network connector between Siemens fire-only FACPs and
with intelligent voice-communication systems.
Model VN2001-A1 mounts in either or both of:
▪ Voice CPU Card, Model VCC2001-U1
[used in voice systems]
▪ Modular Ethernet Switch, Model FN2012-A1
[for use in FACP-only connections]
Single-Mode Ethernet Module
The Single-Mode Ethernet Module (Model VN2003-A1)
serves as a network connector between Siemens fire-only
FACPs and with intelligent voice-communication panels, via
single-mode fiber-optic cables.
Model VN2003-A1 mounts in either or both of:
▪ Voice CPU Card, Model VCC2001
[used in voice systems]
▪ Modular Ethernet Switch, Model FN2012-A1
[for use in FACP-only connections]
