Data Sheet

The Bogen Models SBA225 and SBA325 Room
Selector Panels are designed for use with Bogen Multi-
Graphic® and Multicom 2000® Systems.The SBA225 is
also used in Bogen’s PI35A and SI35A Power Intercom
systems. These panels provide call annunciation (using
LEDs) and tone signal in addition to room selection.
The panels use three position, four-pole lever-action
switches with positive detents. In the SBA225, these
switches are used to selectively connect up to 25
speaker-equipped locations to either a PROGRAM,
OFF or INTERCOM channel. In the SBA325,
the
switches selectively connect up to 25 speaker-equipped
locations to either a PROGRAM–A, OFF, or PRO-
GRAM–B channel.
The INTERCOM channel is select
-
ed by means of separate push on/off switches.
Channels ar
e clearly identified with color-coded guide-
lines in accordance with the Multi-Graphic operating
method.
Calls fr
om staff stations are initiated by a momentary
depr
ession of a call origination switch, which lights the
corr
esponding LED
on the selector panel and sounds a
tone signal to bring attention to the call. The LED
r
emains
“on” until the call is acknowledged, at which
time it is automaticall
y cancelled.
The room selector panels permit maximum room
selection to be accommodated in a minim
um of space
.
Each selector panel also has provisions for accommo-
dating the add-on Bogen Model TZMA Time Zone
Module Adapter, providing up to six zones of time sig-
nalling, and/or the Model SCR25A Call-In Module, pro-
viding the circuits necessary when using call origination
switches which do not contain silicon-controlled recti-
fiers.
The room selector panels are designed to provide
years of unfailing trouble-free operation. The switches
are ruggedly constructed to withstand heavy usage and
are designed with positive detents to assur
e proper
positioning. Lever switches are self-wiping to prevent
erratic operation, and precious metal contact surfaces
ensur
e lo
w contact r
esistance and consistent operating
reliability.
Switch handles ar
e permanently affixed to the switch
shafts, eliminating troublesome r
eplacement pr
oblems.
Further assurance of trouble-free operation is provid-
ed by the LEDs, which are designed to give years of effi-
cient ser
vice
.
