Product Description

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 PROGRAM–
B channel. The INTERCOM channel is selected
by means of separate push on/off switches.
Channels are clearly identified with color-coded guidelines
in accordance with the Multi-Graphic operating
method.
Calls from staff stations are initiated by a momentary
depression of a call origination switch, which lights the
corresponding LED on the selector panel and sounds a
tone signal to bring attention to the call. The LED
remains “on” until the call is acknowledged, at which
time it is automatically cancelled.
The room selector panels permit maximum room
selection to be accommodated in a minimum of space.
Each selector panel also has provisions for accommodating
the add-on Bogen Model TZMA Time Zone
Module Adapter, providing up to six zones of time signalling,
and/or the Model SCR25A Call-In Module, providing
the circuits necessary when using call origination
switches which do not contain silicon-controlled rectifiers.
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 assure proper
positioning. Lever switches are self-wiping to prevent
erratic operation, and precious metal contact surfaces
ensure low contact resistance and consistent operating
reliability.
Switch handles are permanently affixed to the switch
shafts, eliminating troublesome replacement problems.
Further assurance of trouble-free operation is provided
by the LEDs, which are designed to give years of efficient
service.
