CONFIGURATION 12:
DFT120 & TAMB2 WIRING DIAGRAM / GROUND START TRUNK OR STATION LEVEL
In this configuration, the telephone output is connected to the Bogen Telephone Access Module model TAMB2; the TAMB2 module is
connected to the Bogen Digital Feedback Terminator model DFT120; and the DFT120 is connected to the PCM2000 system. The
TAMB2 module is activated by the telephone system and, at the same time, the DFT120 is activated by the TAMB2ʼs normally open
contacts. Using digital technology, the DFT120 stores the DTMF tones and the paging audio. When the TAMB2 closed contacts are
removed from the DFT120, the DFT120 activates the PCM2000 system also using normally open contacts, and plays the page (audio).
In addition to the above equipment, you will also need a 24V DC power supply and two RJ11 modular boxes.
INSTALLATION:
STEP 1: Assemble Modules PCMTIM to PCMCPU and to PCMZPM (see Illustration/Instructions on Appendix page 37,
then return to this page and complete the following Steps).
Note: DO NOT
connect the PCMPS2 (power supply) at this point.
STEP 2: Connecting the Paging Amplifier
• Locate the terminals on the PCMCPU module labeled PA IN/RT and wire to the TIP and Ring (T & R) input on the Bogen
paging amplifier (either TPU-Series, GS-Series, or Classic Series amplifiers).
• Locate the terminals on the PCMCPU module labeled PA OUT/RT and wire to COMMON and either the 25 or 70V output
on the paging amplifier.
STEP 3: Connecting an Analog Line or Ground Start Trunk from the Telephone System to the TAMB2
• Take the Analog Line or Ground Start trunk pair from the telephone system and wire it to the TAMB2 terminals T & R.
STEP 4: Connecting the TAMB2 Module to the DFT120
• Using a 6-pin RJ11 modular jack, connect terminals labeled PT & PR from the TAMB2 to the modular jack terminals R (red) and G
(green).
• Connect terminals labeled N.O. & COM from the TAMB2 to the modular jack terminals Y (yellow) and BK (black).
• Connect a 6-pin RJ11 modular cable from the RJ11 jack to the PAGE IN jacks on the DFT120. Place the switch labeled DL/LS to
the DL (Dry Loop) position.
• Connect terminals labeled +24 & -24 from the TAMB2 to the 24V DC power supply. Bogen recommends using model PRS2403
(24V DC/300mA) or equivalent.
• Connect the DFT120 power supply (supplied with the unit) to the DFT120.
STEP 5: Connecting the DFT120 to the PCMTIM Module
• Attach a 6-pin RJ11 modular jack to the wall next to the PCM2000 unit.
• Connect terminals 3 & 4 from the DFT120 jack labeled AUDIO OUT, to the RJ11 modular jack terminals R (red) and G (green).
• Connect terminals 2 & 5 from the DFT120 jack labeled AUDIO OUT (PLAY contact) to the RJ11 modular jack terminals Y (yellow)
and BK (black).
• Connect a 6-pin RJ11 modular cable between the RJ11 modular jack and the TRUNK/ P/P RJ11 input on the PCMTIM module.
STEP 6: Switch and Control Settings
• Set DIP switches 1 and 3 on the TAMB2 to the ON position for Station access (see TAMB2 manual for complete instructions).
• On the PCMTIM set the one slide-switch to CC (Contact Closure) and the other slide-switch to P/P (Page Port).
STEP 7: Testing Your System
• Connect the power supply PCMPS2 to the PCMCPU module to either the power jack 12V DC input or wire it to the 12V DC screw
terminals observing polarity.
• Connect the power supplies and the amplifier to the AC power outlet 120V AC 60Hz.
• Set the volume on your Bogen amplifier to a half turn.
• Adjust the DFT120 AUDIO OUT volume control to 50%. (You may need to readjust this control higher or lower later, after the test.)
• Access the paging from the telephone system. The RECORD LED on the DFT120 must be lit showing that the DFT120 is already
recording.
• Dial 01 to record ZONE ONE DTMF tone followed by a test page. (Notice that you will not hear audio coming from the speakers at
this point.)
• Hang-up the handset. The PLAY LED on the DFT120 must light showing that the DFT120 is playing the page and you must be able
to hear the page.
• If the page is too low, adjust the control for optimal operation.
