The Bogen TAMB2/PS Telephone Access Module is a unique, dual-purpose voice paging adapter
designed as an interface from a telephone system to a paging system.
This versatile unit offers the capability of station port or trunk port operation, and is compatible with
the full range of analog telephone port types. Advanced design and Bogen dependability make the
TAMB2/PS the perfect choice for simple or complex telephone paging applications.
A background music input (with stereo-combining RCA jacks and volume control), which will accept a line-
level input from a background music source, is provided. This input permits the use of background music
during a page with central paging amplifiers that have no muting provision.

The telephone-access voice-paging adapter shall
be a Bogen Model TAMB2 (or TAMB2PS) capable
of providing either trunk port or station port
access to paging amplifier, multi-zone paging
adapter, or talk back amplifiers.
The adapter shall have station port compatibility,
2-wire analog with a ringer equivalence number of
1.3B, and trunk port compatibility with 2-wire loop
start or ground start. The paging frequency
response shall be 200 Hz to 8000 Hz, ±1 dB, and
the input/output impedance shall be 600 ohms,
nominal.
All operational modes require the unit to be sup-
plied with 24V DC @ 150 mA max draw. Reversal
of the power supply connection polarity will not
damage the unit. The unit shall be capable of gen-
erating an 800 Hz (± 20%), 1/2-second duration
signal to be used as a pre-announce or confirma-
tion tone; the tone level shall be controlled by an
adjustment that shall be accessible without
removing the cover.
When used in the station access mode, the
device shall be capable of three methods of
release following a page: (1) Loop Current
Interruption CPC Pulse, (2) Voice-Operated
Disconnect, and (3) Default Disconnect Timer.
The loop current interruption detection circuit
shall, if the particular line to which the device is
connected issues a disconnect signal (a loss of
loop current for longer than 30 milliseconds),
recognize this signal and immediately disconnect
the device from the line. The voice-operated
disconnect circuit shall be enabled/disabled via
mode switches or an external signal.
A default disconnect timer circuit shall set the
maximum time allotment for paging and ensure
that the unit will always disengage the line if the
other disconnect circuits are inoperative. The
default disconnect timer duration shall be
adjustable from 1 to 200 seconds and the VOX
disconnect timer duration shall be adjustable from
1 to 11 seconds. Time duration is controlled using
DIP switches and rotary controls. Both timers can
be independently inhibited.
When used in the trunk port access mode, the
device shall automatically terminate paging
access upon release of the trunk port.
A stereo combining RCA-type input shall be
included to accept a line-level input from a
suitable background music source. A control shall
be provided to set the background music volume.
One C-Form (N.O. and N.C.) set of contacts shall
be provided for use with auxiliary equipment. The
contacts shall be rated at 30V DC, 2A/125V AC,
0.6A /110V DC, 0.6A (resistive).
The device shall be mounted in a steel enclosure
and finished in black enamel with white lettering.
It shall be listed to UL standard 60950 and com-
ply with Part 68 of FCC Rules and Regulations.
The overall dimensions shall be 8-1/2" W x 1-3/4" H
x 3" D. The product weight shall be 2 lb.
Capable of wall-mount, single-unit rack mount (with
optional rack kit), or side-by-side dual-unit rack
mount.
Power supply is required for TAMB2, power supply
included with TAMB2PS
