CONFIGURATION 8:
TWO-WAY TALK BACK EXTENDED PAGING SYSTEM
This configuration is essentially the same as the two-way paging system described previously on page 17. The main difference is the
addition of a satellite assembly.
The required setup includes: PCMTIM - 2 PCMCPU - PCMTBM - 4 PCMZPM - 2 PCMPS2
Note: Talk Back is only available in High-Power Zones with 25 & 70V AC speakers.
The paging access output from the telephone system must support two-way communications.
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: Assembling Satellite Modules PCMCPU to PCMZPM (see Illustration on page 18)
• Plug the 6-pin power connector from the PCMZPM module to the PCMCPU module jack (J2.) Be sure that the locking ridge
faces the header wall. (Green wire to the top).
• Plug the 26-pin ribbon cable from the PCMZPM module to the PCMCPU module 26-pin connector (J1). Be sure to align the
polarizing tab in slot. (Pin 1 red stripe to the top).
• The satellite systems are usually installed below the the master assembly and must be within 3 feet of each other.
• Use an RCA cable to connect the PCMCPU modules from DATA LINK to DATA LINK RCA connectors. (See drawing on page 18)
STEP 3: Switch Settings
• Set the two slide switches on the PCMTIM to match the paging output setting from the telephone system based on the type of
interface used. See the first bullet within 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. Then return to this page.
• Set the SYS-ID DIP switches on the master PCMCPU module to the OFF position (to the left).
• Set the SYS-ID DIP switches on the first satellite PCMCPU module to the following configuration: switch 1 to the ON position
(to the right), switches 2, 3, & 4 to the OFF position (to the left). See additional SYS-ID settings on page 36.
• Set the RUN-PROGRAM switch on each PCMCPU to the RUN mode (up).
• Set the TALK BACK switches on the PCMZPM modules to the ON position (to the right) for all zones.
• Set the OUTPUT switch on each PCMZPM module to the HI-PWR position (down).
STEP 4: Testing your System
• Connect one PCMPS2 power supply to each PCMCPU module to either the power jack 12V DC input or wire it to the 12V DC
screw terminals, 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).
• 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
• Locate the terminals on the PCMZPM module labeled ZONE A. These terminals have two connections marked + and - .
Wire your speakers for ZONE ONE to these terminals. Observe polarity (-) to common (+) to selected tap setting.
• Follow the same procedure for the terminals labeled ZONE B for ZONE TWO, and the terminals labeled ZONE C
for ZONE THREE.
STEP 7: Testing your System
• Connect a PCMPS2 power supply to each 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 op-
eration.
• Set the Bogen amplifier to the desired volume level.
