This TAMB2 Telephone Access Module from Bogen Communications is designed as an interface between a telephone system and a paging system, providing dual-purpose voice paging. It's compatible with the full range of analog telephone port types, and is capable of station port or trunk port operation. Music from a background music source (with stereo-combining RCA jacks and volume control) is possible via a line-level input, which allows background music to be used during a page with central paging amplifiers don't have a muting provision. This module is ideal for simple or complex telephone paging situations. A 24V power supply is sold separately and is required for all modes of operation. Loop start, ground start, and station port (90V ring up) compatibility 600-ohm output Pre-announce and confirmation tones (defeatable) Adjustable tone volume Works with paging-only and two-way (talk back) systems Background music input with volume control Suppresses background music during paging Station access disconnect is dynamically controlled using a combination disconnect timer, and VOX disconnect timer or Calling Party Control (CPC) signal detection Station port maximum page times from 1- 200 seconds Disconnect VOX timer is adjustable from 1 to 11 seconds of silence VOX and default timers independently inhibitable Calling Party Control (CPC) signal from switch immediately disconnects station port 24V Talk Battery 1 Rack space unit height Flexible Mounting Configuration: wall, single unit rack, and dual side-by-side rack mount Easily accessible controls and switches Trunk Timer feature helps prevent system blockage 24V power supply required for all modes of operation (150mA min. capacity) 1 C-Form (N.O. and N.C.) contact pair available for operating external equipment Pluggable terminal strip connectors FCC Part 68 registered; ETL Listed Frequency Response Paging Frequency Response: 200 - 8000 Hz, ±1 dB Impedance Input/Output Impedance: 600 ohms, nominal Ringer Equivalence 1.3B Compatibility Station Port: two-wire ring start Trunk Port: two-wire loop start or ground start Pre-announce/Confirmation Tones 800 Hz, ±20%, one-half second duration Default Disconnect Timer 1 to 200 seconds, adjustable or inhibit VOX Disconnect Timer 1 to 11 seconds, adjustable or inhibit Auxiliary Contact Rating 0.6 A @ 125 VAC resistive 0.6 A @ 110 VDC resistive 2.0 A @ 30 VDC resistive Connection Terminal Pluggable screw terminal Power Requirements 24 VDC @ 150 mA (sold separately) Operating Temperature Range 32 to 120°F (0 to 49°C) Finish Black enclosure with white lettering Dimensions 8.5 x 1.75 x 3" (21.59 x 4.44 x 7.62 cm) Weight 2.0 lb (0.9 kg) Packaging Info Package Weight 3 lb Box Dimensions (LxWxH) 9.4 x 5.6 x 2.2"
