Overview

Description

The Bogen Model PCMCPU is the microprocessor module for the Bogen PCM

Zone Paging System. One module is required per assembly (up to three PCMZPM

zone modules). The PCMCPU module provides power, data and audio connec-

tions for the PCM system.

The PCMCPU module is connected to other PCM modules electrically through in-

ternal cables. Modules are mechanically joined by sliding together interlocking tabs

and securing with a screw on the rear panel. The system is designed to be wall-

mounted with the modules side by side like books on a shelf, the PCMTIM is far left,

the PCMCPU is first from left and the (first) PCMZPM module is on the right.

(Arrange as shown in illustration on page 7.)

The PCMCPU module includes a set of DIP switches that set the System ID,

a POWER LED, a PROGRAM/RUN switch, a DATA LINK RCA jack (used to con-

nect to satellite systems), power in jack/terminals, and audio connections for PA, low-

power BGM, high-power BGM, emergency/shift change trigger and auxiliary contacts.

PCM2000 System

Minimum system configuration consists of three modules:

PCMCPU, PCMTIM, and PCMZPM provides 3 Zones of paging. To this, you can

add up two additional PCMZPM modules to a maximum of 9 zones. If more than

9 zones are required, satellite assemblies can be added to bring total capacity to

99 zones. Also a talkback module (PCMTBM) can be added for 2-way communi-

cations.The PCM2000 system provides the following features and functions:

Voice Channel

• Up to 99 zones of paging (in 3 zone increments) and sub-zone group paging

(up to 32 zone groups, each with up to 99 zones)

• Override paging (using loop start or contact closure)

• Talkback paging (centrally-amplified zones only)

• High-powered central paging (can be combined with Low Power Paging)

• Low-power paging to amplified speakers (can be combined with

High-Power Paging)

• Privacy beep on talkback zones

• Pre-announce tone

PCMCPU

Background Music (BGM)

• Low-power distributed (buffered for up to 50 amplified speakers)

• High-power, using dedicated BGM amplifier

• High-power using a single paging/BGM amplifier

• BGM disable to individual zones

• Local BGM input on each individual zone module

Signaling

• Night ringer (90V or contact closure activation)

• Code calling (2 types - echo & pattern)

• Emergency/shift change tone (tone and duration selectable)

Other Features

• DTMF setting of all operating parameters

• External C-form relay contacts

• Relay driver output per zone

• Non-volatile memory for setup data (no backup battery required)

Installation

Assembling Modules

To assemble modules together, place them side by side starting with the left most

module of the assembly (for master system assembly, PCMCPU). Plug the ribbon

cable connector into its header (see drawing for orientation). Then plug the 6-pin

connector onto its header.

NOTE: It is very important to check for proper orientation of this connector

(see illustration).

NOTE: If the 6-pin connector is installed backwards, the power light on this mod-

ule (and possibly the entire assembly) will not light when powered up. Correct this

by separating the modules and locating the reversed 6-pin connector.

Place the modules close together and dress the connector cables away from the

sheet metal so that they will not get pinched. Push the two units together while

aligning the locking tabs on the top and bottom sides of the left unit with the lock-

ing slots on the right unit. At this point the left unit will be positioned slightly ahead

of the right unit. Now slide the left unit back against the right unit 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.

NOTE: It is usually easier to run the screw in and out of the screw clamp tab,

to cut a thread, before assembling the units together.

Power

The PCM system requires 12V DC 1.5A. Use the PCMPS2 power supply. Plug the

power supply into the POWER jack on the PCMCPU module. Power can also be

connected to the 12V DC terminals on the connector block.

For a system with no satellites, set SYS ID DIP switches on PCMCPU module to

the position shown. See section on System Expansion in this manual for addi-

tional information on setting system IDs in expanded systems.

Program/Run Switch

The Program/Run switch must be set to the PROGRAM position during system

programming and the RUN position during normal operation. Refer to the instruc-

tions included with the PCMTIM module for programming instructions.

Audio Connections

Centralized amplifier connections are made to the screw terminals marked PA IN

and PA OUT on the PCMCPU module. Connect PA IN and RT (return) to the audio

input on the paging amplifier. Connect the high-power (70V) output of the amp to

the PA OUT and RT terminals.

Low-Power BGM

Connect BGM source to the LPBGM IN & RT terminals (Connect signal ground or

shield to RT terminals and the hot to IN). This provides low-level BGM signals to the

PCMZPM modules with LO PWR OUTPUT selected. This input is unbalanced.

High-Power BGM

Connect BGM source to the input of a 70V amplifier. Connect the high-power (70V)

output of the amplifier to the HPBGM IN & RT terminals (amplifier common should

connect to RT). This provides high-power background music signal to the PCMZPM

modules with HI PWR OUTPUT selected.

Emergency/Shift Change Trigger

External input control is available to trigger a tone signal from the PCM2000 over

the paging system. Shorting EM/SC to the GND terminal will produce a user-

programmed tone into a preselected group of zones. See Programming section of

the PCMTIM manual for information on programming the EM/SC feature.

AUX/GND Contacts

These contacts are used to synchronize with an external master clock. Shorting these

terminals resets the real time clock in the PCMTBM module to a user preset time. See

the PCMTIM manual Programming section for further information on this function.

Section 3

System Expansion

Concept

In situations where it is necessary to extend beyond 9 zones of paging, satellite

systems and a master must be used. Each satellite system is responsible for the

specific group of zones as determined by the setting of its SYS ID DIP switches.

The master system transmits its commands on the Data Link bus to all satellites at

the same time, but only the specifically addressed satellite responds.

NOTE: A satellite system consists of 1 PCMCPU module and 1 to 3 PCMZPM

modules. PCMTIM and PCMTBM modules are not used and will not work in a

satellite system.

Audio Wiring

Audio wiring is daisy-chained from one assembly to another. The illustration on

page 15 shows the daisy chain audio wiring between system assemblies (wiring to

the BGM sources is only done on the master system). The same wiring scheme is

used between adjacent assemblies.

Data Link Wiring

The DATA LINK ports of the system's PCMCPU modules are connected using RCA

cables. For a system with one satellite, a standard male-to-male RCA cable can be

used. For systems with more than one satellite, the recommended interconnecting

cable consists of a single female RCA connector with two male RCA connectors

(see illustration below). It is also recommended that the distance between adjacent

satellite systems does not exceed 3 feet, and that all DATA LINK connections are

securely made and well seated. Bad connections will result in operational failures

and/or inconsistent operation.

Satellite Zones & SYS ID Switch Positions

System ID

Once the satellite systems have been wired together, the satellite ID numbers can

be assigned. The ID for the master system (the one which has the PCMTIM module)

must be set to zero (all SYS ID switches set to "0"). Although satellite systems can

be numbered in any order, it is best to number them sequentially, starting with "1"

and following the way in which they are daisy-chained together. The table below

shows the SYS ID switch settings for the available satellite numbers and the zones

that each satellite is responsible for. After satellites have been numbered, you may

want to mark the actual zone numbers for each zone in the white area to the left of

the zone terminal screws. Use an indelible felt-tip marker. The lowest numbered

zone in the satellite system is the top zone in the PCMZPM module adjacent to the

PCMCPU module. The highest zone in the satellite is the bottom zone in the last

PCMZPM module.

After satellite systems have been wired and ID numbers assigned, the system can

be powered up. If it is necessary to change the ID number of a satellite after the

system has been powered, you must remove and then reapply power TO THAT

SATELLITE after changing switch settings.
