3.1. Adding PCMZPM Modules
The LUPCMALL is pre-assembled to accommodate 3 zones of paging. If your installation requires 4 to 9 zones, you can add
one or two Zone Paging Modules (PCMZPM). A total of 3 PCMZPM modules (9 zones total) can be used on a LUPCMALL
assembly. If your installation requires more than 9 zones, you will need one or more LUPCMADD units to allow system
expansion beyond 9 zones. Install the extra PCMZPM modules before mounting and wiring the PCM System assemblies.
(Refer to the LUPCMZONE installation manual.)
NOTE:
LUPCMADD Paging Control System Expansion Assemblies and Zone Paging Modules can only be added when the
previous assembly contains 3 PCMZPM modules; otherwise, the system will not operate.
3.2. Mounting the PCM System
The Paging Control System Assemblies can be either wall- or rack-mounted.
3.2.1. Wall Mounting
1. After assembling the unit (if necessary) hold the unit level against the surface to which it will be mounted.
2. Mark where the mounting screws should be positioned.
3. Set the assembly aside and install the screws leaving about ¼" of the screw sticking out of the surface.
4. Slip the assembly over these screws and tighten them snuggly.
3.2.2. Rack Mounting
1. Position the left side of the completed PCM assembly (any additional PCMZPM modules should have already been
added) over one of the rack mounting adapters. Refer to Figure 3-1 and use the correct holes for the number of modules
in the assembly (4, 5, or 6 as shown).
2. Secure the left side of the PCM system to the rack adapter using two of the truss head sheet metal screws.
3. Secure the right side of the PCM system to the other rack adapter using the holes for the number of modules in the
assembly and the remaining 2 truss head sheet metal screws.
4. Secure the assembly to a 19" rack (rack screws not supplied).

20. SYS ID - Switch bank used to set unique address of the PCMCPU module when other LUPCMADD assemblies are used
in the paging system.
21. RUN/PROGRAM Switch - Switch must be set to the PROGRAM position before any system programming can be done.
Return to RUN position for normal system operation. Locking plate ensures that switch will not be accidentally set to
program mode. Switch only needs to be changed on the LUPCMALL main assembly. LUPCMADD assemblies always
stay in RUN mode (see Section 8.1).
22. 12V DC Power Jack - PCM system power supply connects to this jack.
[13]
5.1. Telephone System Connections
The PCMTIM module is the telephone interface module for the PCM Paging Control System. The PCMTIM provides the
telephone interface (including talk battery), night ringer input, emergency override input, and auxiliary relay contacts for the
system. The module is also responsible for all tone signaling features.
The PCM connects to virtually any telephone system: PBX station lines and CO lines, PBX loop start trunk ports, PBX ground
start trunk ports, and page ports (using contact closure).
Interface installation consists of setting Slide switches and connecting with modular (RJ11) telephone plugs.
Refer to the appropriate procedure in this section to connect the PCM System to the telephone system.
Note: In all cases, make sure that power is off to the PCM and any amplifiers being connected to it before performing the
installation.
5.2. PBX Loop Start Trunk Port
In this configuration, the PCM unit supplies a 48V talk battery and loop current detection from pins 3 & 4 of the TRUNK
jack on the PCMTIM module to the loop start trunk in the telephone system. There are two modes of operation for loop
start trunk.
(1) When the unit detects a loop resistance between TIP and RING, it activates. When
the loop opens, the page ends. Pins 1, 2, 5 & 6 are not used in this configuration.
Note: Default and VOX timers are not used in this mode.
(2) The unit will operate as in mode one, except it will also provide a one-second hook
flash after the expiration of the VOX and/or Default timers. Operation in this mode
will enable the unit to automatically disconnect itself from the loop start trunk of
the PBX. This will prevent the paging system from being locked up indefinitely in
the event a telephone is accidentally left off hook after a page has been completed.
The feature codes are 014 to inhibit and 015 to enable this feature. The default
feature code is 014 (OFF).
1. Make sure that power is off and all connections completed before proceeding.
2. Move the Slide switches on the module to the position shown in Figure 5-1.
3. Use a modular telephone cord to connect the module to the phone system. Plug one
end of the cord into the Loop Start Trunk (using a modular jack) and the other end in
to the TRUNK jack on the module.
The center two conductors are Tip and Ring (48V DC) and have a specific polarity. If the
polarity of the trunk is opposite, you can use a reversing modular cord to make the
connection or reverse the connection through a modular block. Refer to
Figure 5-2 for more information.
IMPORTANT: The polarity of the Tip & Ring contacts of the RJ11 jack for the Trunk and Override were chosen so that
when a standard modular cord (one with the tops of both end plugs on the same side of the flat cable) is used to connect the
PCM to a modular wall block, the modular block G (Tip) terminal will be positive with respect to the R (Ring) terminal.
Because of variations in types of modular cords and when stripping a modular cord for direct connection, always check the
polarity of the center conductors or R & G terminals to determine Tip & Ring (the positive lead is Tip and the negative lead
is Ring).

[14]
5.3. PBX Ground Start Trunk Port
In this configuration, the PCM unit supplies a 48V talk battery and loop current detection from pins 3 & 4 of the TRUNK
jack on the PCMTIM module to the ground start trunk in the telephone system. There are two modes of operation for
ground start trunk.
(1) When the ground start trunk grounds Ring, the unit responds by closing the
connection to Tip, which completes the access procedure. When the loop is opened,
the page ends. Pins 1, 2, 5 & 6 are not used in this configuration.
Note: Default and VOX timers are not used in this mode.
(2) The unit will operate as in mode one, except it will also provide a one-second hook
flash after the expiration of the VOX and/or Default timers. Operation in this mode
will enable the unit to automatically disconnect itself from the ground start trunk of
the PBX. This will prevent the paging system from being locked up indefinitely in
the event a telephone is accidentally left off hook after a page has been completed.
The feature codes are 014 to inhibit and 015 to enable this feature. The default
feature code is 014 (OFF).
1. Make sure that power is off and all connections completed before proceeding.
2. Move the SLIDE switches on the module to the position shown in Figure 5-3.
3. Use a modular telephone cord to connect the module to the phone system. Plug one
end of the cord into the Ground Start Trunk (using a modular jack) and the other end
in to the TRUNK jack on the module.
The center two conductors are Tip and Ring (48V DC) and are polarity sensitive. If the
polarity of the trunk is opposite, you can use a reversing modular cord to make the
connection or reverse the connection through a modular block. Refer to Figure 5-4 for
more information.
IMPORTANT: The polarity of the Tip & Ring contacts of the RJ11 jack for the Trunk and Override were chosen so that
when a standard modular cord (one with the tops of both end plugs on the same side of the flat cable) is used to connect the
PCM to a modular wall block, the modular block G (Tip) terminal will be positive with respect to the R (Ring) terminal.
Because of variations in types of modular cords, and when stripping a modular cord for direct connection, always check the
polarity of the center conductors or R & G terminals to determine Tip & Ring (the positive lead is Tip and the negative lead
is Ring).
4. Use 24-gauge solid wire to connect the GS terminal on the module to the PBX ground. This is typically the AC ground
for the PBX system.
IMPORTANT: It is very important that no other terminals of the PCM system connect to AC ground when using the ground
start interface. Also, the case of the PCM system cannot be connected to AC ground. If the system is not working and no PCM
terminals (except the GS terminal) are directly connected to AC ground, there may be an indirect connection. Check the
connections to any equipment with a 3-wire AC plug. Make sure that unbalanced inputs and outputs of this equipment are
isolated using a model LUWMT1A transformer (Com Code 405891680) before connecting the equipment to the PCM.
The PA OUT and HPBGM terminals on the PCM do not have to be ground-isolated.

5.4. PBX Page Port
In this configuration, the unit responds to a contact shorting the closure source to its
return. When the short is removed, the page ends. Audio is provided to the system through
a separate pair of leads.
1. Make sure that power is off and all connections completed before proceeding.
Note:
Make sure that the page port produces DTMF tones. The page port must also
be bi-directional in order to use talk back.
2. Move the SLIDE switches on the module to the position shown in Figure 5-5.
3. Use a modular telephone cord to connect the module to the phone system. Plug one
end of the cord into the Page Port and the other end in to the PAGE PORT jack on
the module.
The center two conductors are used for dry audio and the connectors on either side are
connected to the page port contact closure. The maximum resistance of the page port
contact closure is 1000 ohms. Refer to Figure 5-6 for more information.
5.5. PBX Analog Station Port
In this configuration, the unit 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 is started (if enabled). This 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 page length.
The unit will also respond to CPC pulses (short losses of loop current). When a CPC pulse
is detected, the unit will immediately drop the line.
1. Make sure that power is off and all connections completed before proceeding.
2. Move the TEL INT SEL (SLIDE) switches on the module to the position shown in
Figure 5-7. Use the tip of a pen or other pointed instrument to move the switches.
3. Use a modular telephone cord (minimum 2-conductor) to connect the module to the
phone system. The center two conductors are Tip and Ring and are not polarity
sensitive (see Figure 5-8). Plug one end of the cord into the PBX or CO modular jack
and the other end in to the STATION jack on the module.
4. Set Default and VOX timers. See System Programming, Section 11.
Note:
The default timeout is factory set to 30 seconds, and the VOX timeout is set to
6 seconds. If both the default and VOX timers are inhibited, the only way to
disconnect the system from the station line is the CPC pulse.

5.6. Night Ringer
The PCM Night Ringer signaling feature is designed to alert personnel to incoming calls after normal business hours. The
feature can be activated either by a 90V ring signal or by a contact closure. In the factory default configuration, the night ringer
sounds over all zones, however, a zone group can be programmed which will sound the night ringer only over a user-selected
group of zones.
The night ringer normally sounds a simulated ring tone. The ringer can be programmed to sound a chime tone or a tone
provided by a user-supplied external tone generator (see page 35).
Follow the instructions below for night ringer connections. Refer to the System Programming, Section 11, to set up a night
ringer zone group or to change to ringer tone.
To physically connect the Night Ringer:
1. Make sure that the power is OFF.
2A. For 90V Night Ring (RJ11) Jack Connection
Plug a modular cord into the 90V NGT RNG (RJ11) jack. The center conductors are
used for Station Access. The flanking conductors are for the 90V Night Ring Signal.
2B. For Contact Closure Connection
Screw terminal connections are provided for Night Ring Contact Closure
activation.
Maximum contact resistance for contact closure activation is 1000 ohms.
NGT RNG is the contact closure source (+5V).
RT is the contact closure return (GND).
Note: The Night Ring feature has priority over background music only. There is a
5 second delay after the night ring stops before background music is restored (bridges
inter-ring pause).
3. Reconnect power.

The Override is a non-programmable feature that lets the caller take priority over all paging functions and make a systemwide page to all speakers. The feature can be activated using a loop start trunk or dedicated telephone. Provisions are also
included to interface with other signaling equipment.
The Override feature includes a quad beep pre-announce tone that can be enabled or inhibited. (The default is inhibited). See
System Programming, Section 11 to enable the tone.
1. Make sure that power is off and all connections completed before proceeding.
2. Plug modular cord into OVERRIDE (RJ-11) jack.
The center two conductors interface directly to a Loop Start Trunk or dedicated phone (see
Figure 5-10). When the trunk becomes active, the PCM goes into Override mode.
Also, see Connecting to an External Audio Source, page 53.

6. Paging Amplifier Connections
The paging amplifier audio connections are made to the PCMTBM module terminal strip. If the amplifier has a paging control
input, this is connected to the RLY TWO terminals on the PCMTIM module (see Figure 6-1). The paging amplifier must have
a balanced 600-ohm input. The amplifier should be located close to the PCM system to keep cable lengths reasonably short.
NOTE: To make all audio connections, use 22 AWG shielded, twisted pair on all wire runs. Com Code: 401882956, PEC
Code: 2734-SPK.
CAUTION: Make sure the amplifier is turned off or unplugged before wiring.

The PCM system is very flexible in how it can provide background music throughout the system:
• Background music can be continuously supplied to all zones not being paged. (Requires two amplifiers of the same power
rating.)
• Background music can be supplied by the same amplifier that is supplying paging. (Music input is available on amplifier.)
• Background music can be supplied by same amplifier that is supplying paging. (No dedicated music input available on
amplifier.)
• Background music or different background music can be supplied to a select group of zones.
• Background music can be supplied to self-amplified (LO-PWR) zones.
• Background music can be inhibited in select groups.
The BGM SRC terminals are used to control background music operations when using a single power amplifier that does not
provide a separate music input. This feature is only used when a single amplifier will be used for both background music and
paging (background music is lost in all zones when a page is made).
NOTE
: This input and its associated control is not used when using amplifiers with separate music inputs and paging control
terminals because background music is supplied directly to the amplifier.
7.1. Helpful Hints When Connecting Background Music to the Paging Control System
1. When using the BGM SRC (background music source) input on the PCMTIM as input for background music, the music
is muted to all speakers when any zone is selected. The source input signal is line level.
2. When the HPBGM (high-powered background music) input on the PCMCPU is used, music is muted only in the zone
selected. The source input has to be an amplified signal.
3. When the LPBGM (low-powered background music) input on the PCMCPU is used as an input for background music,
music is muted only to the zone selected. In this application, either amplified speakers or an amplifier per zone is used.
PCMZPM output power switch is set to LO-PWR. The input background music is line level.
4. When the Local BGM input on the PCMZPM is selected as input for background music, music is muted only to the zone
selected. An amplified signal is required at this input if using 70V speakers.
NOTE:
When you want to mute the background music only to the zone in which you are paging, refer to 2, 3 or 4 above.
