SBA325

• Color-coded guidelines

• Built-in LED annunciators

• Space-saving design

• Modular versatility

The Bogen Models SBA225 and SBA325 Room Selector Panels are designed for use with Bogen MultiGraphic® 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, switches selectively connect up to 25 speaker-equipped locations to either a PROGRAM–A, OFF, or PROGRAM–B channel. ed by means of separate push on/off switches.

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 assur positioning.

Specifications

The Room Selector Panel shall be a Bogen Model _________ (enter SBA225 or SBA325), or approved equal.

– Use the following 2 paragraphs for SBA225 –

The panel shall be capable of connecting up to 25 speaker-equipped locations to a program, off or intercom channel. The panel shall provide 25 lever-action three-position, four-pole selector switches with positive detents and 25 red LEDs.

Switch positions shall be legibly identified as PROGRAM A, OFF and INTERCOM C, each with a colorcoded guideline in accordance with the operating method used in Bogen Multi-Graphic Systems.

– Use the following 3 paragraphs for SBA325 –

The panel shall be capable of connecting up to 25 speaker-equipped locations to either of two program channels,

or to an inter

off,

com channel. The panel shall provide 25 lever-action three-position four-pole switches with positive detents, 25 push on/off intercom channel selector s

witches and 25 r

ed LEDs.

Switch positions shall be legibly identified as PROGRAM–A, PROGRAM–B, and OFF O. The intercom channel switches shall be labeled I/C. Each channel shall have a color-coded guideline in accordance with the operating method used in Bogen MultiGraphic Systems.

– Use the remaining paragraphs for both panels –

The individual switches shall be designed for maximum reliability and a life expectancy of over 250,000 operations. Switches which have a lower life expectancy shall not be accepted. Switch handles shall be permanently affixed to the levers. Knobs and handles held in place by friction will not be accepted. Switches shall be selfwiping with precious metal contact surfaces.

The annunciator system shall provide for automatic call cancellation, and shall operate on less than 15VDC to eliminate any shock hazard. Annunciator systems which do not provide automatic call cancellation, or which use holding relays or other mechanical devices will not be accepted.

The room selector panel shall provide for the ready accommodation of add-on TZMA Time Zone Module and/or SCR25A
