CONFIGURATION 7:

TWO-WAY TALK BACK PAGING SYSTEM

This configuration is essentially the same as the one-way paging system described previously.The main difference between the one-way con- figuration and this configuration is that the centralized high-power amplifier is connected to the PCMTBM module instead of the PCMCPU module.The required setup includes: PCMTIM - PCMCPU - PCMTBM - PCMZPM - PCMPS2. Modules must be assembled, from left to right, in this order.

Notes: Talk Back is only available in High-Power Zones with 25/70V AC speakers.The paging access output from the tele- phone system must support two-way communications.

INSTALLATION:

STEP 1: Assembling Modules PCMTIM to PCMCPU to PCMTBM and to PCMZPM (see Illustration on page 38)

•Plug the 6-pin power connector from the PCMCPU module to the PCMTIM module jack (J2.) Make sure that the locking ridge faces header wall. (Green wire to the top).

•Plug the 26-pin ribbon cable from the PCMCPU module to the PCMTIM module 26-pin connector (J1). Make sure to align the polarizing tab in slot. (Pin 1 red stripe to the top).

•Place the modules together and dress the connector cables away from the sheet metal so they will not get pinched.

•Push the two units together while aligning the locking tabs in the PCMTIM module to the locking slots in the PCMCPU module. Slide the two units until the faces of both units are even.

•Secure the two units together by tightening a screw into the screw clamp tab in the back of the unit.

•Follow the same steps to add the PCMTBM module and the PCMZPM modules.

Note: Do NOT connect the PCMPS2 (power supply) at this point.

STEP 2: Connecting Telephone System Paging Output to the PCMTIM

•Refer to paging access modes described previously in Step 2 on pages 5 (paging port/contact closure), 7 (paging port/VOX), 9 (loop start trunk), 11 (ground start trunk), or 13 (station level/Centrex).

STEP 3: Switch Settings

•Set the TEL-INT-SEL DIP switches on the PCMTIM module to match the paging output access from the telephone system based on the type of telephone interface used. (See step 3 on page 5 if using Page Port Contact Closure; page 7 for Page Port VOX; page 9 for Loop Start Trunk; page 11 for Ground Start Trunk; or page 13 for Station Level/Centrex.)

•Set the SYS-ID DIP switches on the PCMCPU to the OFF position (to the left).

•Set the RUN-PROGRAM switch on the PCMCPU to the RUN mode (up).

• Set the TALK BACK switches for the zones requiring two-way talk back to the ON position (right) on the PCMZPM module.

•Set the OUTPUT switch on the PCMZPM module to the HI-PWR position (down).

STEP 4: Testing your System

•Connect power supply PCMPS2 to the PCMCPU module to either the power jack 12V DC input or wire it to the 12V DC screw ter- minals observing polarity.

•At this point all the power LEDs should be lit on each module.

•Access the paging from the phone system and verify access tones (double beep) in handset.

•Speak into the handset and listen.You should be able to hear the Talk Back Relay clicking back and forth inside the PCMTBM module. (You must be near the PCM unit to hear it.)

•At this point, the system should be functioning properly.

•Disconnect Power Supply.

STEP 5: Connecting the Paging Amplifier

•Locate the terminals on the PCMTBM module labeled PA OUT/RT and wire to the COMMON and either 25 or 70V output on the Bogen paging amplifier (either TPU-Series, GS-Series or Classic Series).

•Locate the terminals on the PCMTBM module labeled PA IN/RT and wire to the TIP and RING input on the Bogen paging amplifier.

STEP 6: Connecting 25/70V AC Speakers

•Follow the same procedure described previously on page 5, step 6.

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 Bogen amplifier to the AC power outlet (120V AC 60Hz).

•Set the volume on your Bogen amplifier to a 1/2 turn.

•Access the paging from the telephone system and listen (on the handset) for the confirmation tone (double beep).

•Dial 01 to access ZONE ONE and listen (on the handset and also to the speakers) for a pre-announce tone (single beep). At this point you should be able to hear audio from the location where the speaker for ZONE ONE is installed.

•The volume and delay controls on the PCMTBM module control the audio back into the handset. Adjust these controls for best opera- tion.

•Set the Bogen amplifier to the desired volume level.
