Bogen - SBA225 STATION SELECTOR PANEL 1 3/4"H UPC 765368430134

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.
