One-Height-Unit Enclosure
For each Desigo panel, one (1) red or black back box
supports one (1) red or black outer door, respectively. The
inner door, which is available in black, specifically stores the
system operating units (Models FCM2018-U2 and
FCM2019-U2). The back box supports the fire-terminal
board (Model FTI2001-U1), and optionally supports the
DACT (Model FCA2015-U1).
The one-height-unit enclosure is the smaller housing used
on Desigo panels. The following components comprise a
complete one-height-unit enclosure:
▪ One (1) back box, (Model FHB2001-U1 / R1)
▪ One (1) inner door, (Model FHD2004-U1)
▪ One (1) outer door, (Model FHD2001-U2 / R2)
▪ One (1) clear lens, (Model FHD2006-U1)

4.5" (11 cm.) (D)
Two-Height-Unit Enclosure
The Two-Height-Unit Enclosure is the larger housing for the
Desigo 252 / 504-point FACP.
The following components comprise a complete two-height-
unit enclosure:
▪ One (1) back box, (Model FHB2002-U1 / R1)
▪ One (1) or two (2) inner doors,(Models FHD2004-
U1 or FHD2005-U1)
▪ One (1) outer door,(Model FHD2002-U2 / R2 or
FHD2003-U2 / R2)
▪ One (1) or two (2) clear windows, (Model
FHD2006-U1)
Note: One (1) window is installed for Model FHD2002-U2
/ R2 outer door, and two (2) windows are required for
Model FHD2003-U2 / R2.
Approximate size: 28.5" (72.4 cm.)(H)
20" (50.8 cm.) (W)
6.0" (15.2 cm.) (D)
Inner Doors
There are two (2) inner doors available for Desigo system
enclosures. Model FHD2004-U1 supports one (1) operating
unit {Model FCM2018-U2 or Model FCM2019-U2}, or one
(1) to four (4) LED-option modules (Model FCM2023-U2).
When less than four (4) LED option modules are used, the
blank-option module (Model FCM2022-U2) covers unused
module spaces in the inner door.
Approximate size: 13.25" (33.7 cm.) (H) and 20" (50.8
cm.) (W)

height-unit enclosure, and FHA2036-U1 / R1 is used for the
two-height-unit enclosure.
DIN Rail Kit
The optional DIN Rail Kit (Model FHA2031-U1) mounts in
the back box of a one or two-height-unit enclosure, and
provides connection between internal-system wiring and
field wiring.
