Model
VTO2001-U2
Model
EBA2004-A1
Switch Option Module
The Switch Option Module (Model
VTO2001-U2) is a series of front-end,
illuminated and programmable
pushbuttons primarily mounted in the
middle inner door of each Desigo
intelligent voice-communication FACP.
Each Model VTO2001-U2 module has 24
group-switches, thus totaling 48 LEDs,
and consists of up to 96 multi-color LED-
status indicators:
▪ RED / GREEN / BLUE
variant in the upper
portion [for activation]
▪ one (1) YELLOW-only LED
[for fault or disable]
Each LED switch-group is assigned specific functionality
during the configuration process. Additionally, a pushbutton
{for each affected zone} will illuminate to acknowledge the
command has been received at the Voice System CPU Card,
Model VCC2001-A1.
If no microphone is used, up to eight (8) Model VTO2001-
U2 switch-option modules can be used in a given three-
eight-unit (3HU) enclosure (Model FHD2007-U2 / R2) –
▪ four (4) modules in the middle inner-door, Model
FHD2004-U1
▪ four (4) additional Model VTO2001-U2 modules in
the bottom inner-door, Model FHD2004-U1
100W Booster Amplifier (and Enclosure)
As an option, the Model EBA2004-A1 Booster Amplifier is a
main board that allows for expansion of speaker zones for
additional power to a Desigo intelligent voice-
communication system.
Model EBA2004-A1 consists of a single board with two (2)
50W amplifiers, one (1) built-in battery charger, and
removable terminal blocks for all field wiring.
Model FH2016-U1/R1 is the enclosure used to house the
100W Booster Amplifier.
Approximate size:
23.6" (60 cm.)(H)
18.1" (46 cm.)(W)
5.1" (13 cm.)(D)
Battery Fixing Bracket
The battery fixing bracket (Model FHA2044-U1) is
specifically used in all Desigo IVC system configurations ―
housing and securing 33AH system battery sets, which
provide auxiliary system power. Model FHA2044-U1 bracket
complies with seismic certification.
DIN rail kit
The optional DIN Rail Kit (Model FHA2031-U1), which also
functions in intelligent voice- communication systems,
mounts in the backbox of a 3HU enclosure, and provides
connection between internal-system wiring and field wiring.
Three-Height-Unit Enclosure
The three-height-unit (3HU) enclosure is the largest housing
available for Desigo panels, and is used exclusively for voice-
system applications.
Orderable in either red or
black, the following
components comprise a
complete three-height-unit
enclosure:
▪ One (1) backbox
(Model FHB2005-U1/R1)
▪ Two (2) inner doors
(Model FHD2004-U1)
▪ Two (2) clear lenses
(Model FHD2006-U1)
▪ One (1) outer door
(Model FHD2007-U2/R2)
▪ One (1) blank plate
(Model FHD2009-U1/R1)
Notes: An enclosure cover (Model FHA2041-R1) is used to
protect the ventilation holes found at the top of
red-only, 3HU backboxes (Model FHB2005-R1).
Model FHA2041-R1 prevents condensation from entering
the FACP, and consequently meets New York City code for
uncovered ventilation holes on fire-systems enclosures.
Approximate size:
42" (106.7 cm.) (H)
21" (53.3 cm.) (W)
7.75" (19.7 cm.) (D).
Three-Height-Unit Backbox
The three-height-unit backbox is part
of the Desigo 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.)(H)
21" (53.3 cm.)(W)
7.75" (19.7 cm.)(D)
