Bogen TAMB2 Specifications

The Bogen TAMB2 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 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 linelevel 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 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 supplied 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 generating an 800 Hz (± 20%), 1/2-second duration signal to be used as a pre-announce or confirmation 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 by an NRTL Safety Agency to UL 60950 and comply 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.
