CONFIGURATION 5:
STATION LEVEL/CENTREX / 3-ZONE / ONE-WAY PAGING / SINGLE AMPLIFIER / 25 & 70V AC SPEAKERS
In this configuration, the PCM unit responds to a 90V AC 20Hz ringing signal in pins 3 & 4 of the STATION/90V NGT RNG jack on the
PCMTIM module and answers after the first full ring. As soon as it answers, the default timer is started. The default timer determines
the maximum length of any page. When a paging zone is selected, the VOX timer (if enabled) is started. This VOX timer repeatedly
resets as long as audio is detected on the line. If no audio is detected within the VOX time period, the page will end. If audio continues
to be detected, the default timer will control the page length. Pins 1, 2, 5 & 6 are not used in this configuration.
Note: In this configuration, the unit will also respond to CPC pulses (interruption of loop current) disconnecting the line.
The required setup includes PCMTIM -PCMCPU - PCMZPM - PCMPS2. Modules must be assembled, from left to right, in this order.
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 Station Level/Centrex from the Telephone System to the PCMTIM Module
• Take the Station Level/Centrex pair from the telephone system and wire it to the RJ11 STATION/90V NGT RNG jack in the
PCMTIM module to pins 3 and 4 (red and green).
• Use a 4 or 6-pin modular cord to connect the RJ11 to the STATION/90V NGT RNG jack on the PCMTIM module.
STEP 3: Switch Settings
• Set the two slide switches on the PCMTIM module for Station Level/Centrex configuration: Set the slide switch labeled
TRUNK/P/P/STATION to the STATION position. Note: Leave the PAGE PORT in the CC position.
• Set the SYS-ID DIP switches on the PCMCPU module to the OFF position (to the left).
• Set the RUN-PROGRAM switch on the PCMCPU module to the RUN mode (up).
• Set the Talk Back DIP switches on the PCMZPM module to the OFF position (to the left) for all zones.
• 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
terminals observing polarity.
• At this point all the power LEDs should be lit on each module.
• Access the Station Level/Centrex line 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 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 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 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 Station Level/Centrex port 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) followed
by your page (audio).
• Follow the same steps for ZONES TWO (02) and THREE (03). Dial [00] for All-Page.
• Set the Bogen amplifier to the desired volume level.
