Bogen TAM-B User manual

The Bogen TAMB 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 currently available telephone systems. Advanced design and Bogen dependability make the TAMB
the perfect choice for simple or complex telephone paging applications.
A background music input (with RCA-type jack and screwdriver-adjustable volume control), which will accept
a line level input from a background music source, is provided. The input permits use of background music
with amplified speaker systems as well as with central paging amplifiers.

The telephone-access voice-paging adapter shall be a
Bogen Model TAMB capable of providing either trunk
port or station port access to paging amplifier/ampli-
fied speakers, multi-zone paging adapter, or talk back
amplifier/amplified speakers.
The adapter shall have station port compatibility, 2-
wire analog with a ringer equivalence number of
1.2B, 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/out-
put impedance shall be 600-ohms, nominal.
When used in the station port access mode, the
device shall be line-powered and shall not require an
external power supply; when used in the trunk port
access mode, it shall operate from 24V DC @ 90
mA, or 48V DC @ 105 mA. The unit shall be capa-
ble of generating an 800 Hz (±20%), 1/2-second dura-
tion signal to be used as a pre-announce or confir-
mation tone; the tone level shall be controlled by a
single screwdriver 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 follow-
ing a page: (1) Loop Current Interruption, (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 maxi-
mum time allotment for paging and ensure that the
unit will always disengage the line if the other discon-
nect circuits are inoperative. The default disconnect
timer duration shall be adjustable from 6 to 35 sec-
onds and the VOX disconnect timer duration shall be
adjustable from 2 to 6 seconds.These controls shall
be accessible without removal of the cover and they
shall be screwdriver-adjustable.
When used in the trunk port access mode, the device
shall automatically terminate paging access upon
release of the trunk port.
An RCA-type jack shall be included to accept a line
level input from a suitable background music source.
A screwdriver-adjustable control shall be provided to
set the background music volume.
One set of normally open contacts shall be provided
for use with the ground start trunk port operation or
for auxiliary equipment control.The contacts shall be
rated at 30V DC, 2A.
The device shall be mounted in a steel enclosure and
finished in black enamel with white lettering. It shall
comply with Part 68 of FCC Rules and Regulations.
The FCC Registration Number and Ringer
Equivalence Number shall appear on the front panel.
The overall dimensions shall be 8-1/8" W x 4-1/2" H
x 1-7/8" D. The shipping weight shall be 2 lb.
