Connections
Loop Start Trunk
Figure 1 illustrates the connection of the ZPM3 to a Loop
Start Trunk port and optional night bell connections. See
Figure 2 if the system requires a 48V talk battery.
Ground Start Trunk
Figure 3 illustrates the connection of the ZPM3 to a Ground
Start Trunk port and optional night bell connections. See
Figure 2 if the system requires a 48V talk battery.
NOTE: The line from the GS terminal of the ZPM3 must be
connected to the PBX ground (usually the PBX AC ground) for
correct operation.
48V Compatibility
If it is necessary to supply 48V talk battery to the trunk port,
a 48V DC power supply (Bogen Model PRS48) is also
required. Connect power supplies as shown in Figure 2.
NOTE: In applications where RI & TI Terminals are connected to
R & T Terminals, a regulated power supply with very low AC ripple
must be used (PRSLSI recommended). Any ripple on the power
supply will appear as “hum” on the paging audio.
Paging Port
Figure 4 illustrates the connection of the ZPM3 to a Paging
Port. It is important that the port provide an audio pair
that does not suppress the DTMF information. Also,
the port must provide a normally-open contact closure (or
use VAR1). When using the ZPM3 with the paging port,
the talk battery and audio are separated, thus providing
virtually noiseless switching.
Station Port
Figure 5 illustrates the connection of the ZPM3 to a Station
Port. It is necessary to use a TAMB2 Telephone Access
Module in all station port applications. Refer to the
TAMB2 installation instructions to connect the TAMB2 to
a station port. If the external contact closure of the TAMB2
is in use for another function, connect the ZPM3 to the PT
and PR terminals of the TAMB2 as if it were a loop start
trunk.
NOTE: To reduce system hang-up transients, it is preferable to
connect as shown in Figure 5.

Connections
Central-Amplified Talk/Talk Back Systems with
Page Muted BGM
The configuration illustrated in Figure 6 mutes BGM in all
zones when a page is made. The installation requires a pag-
ing amplifier and, in a talk back system, a talk back amplifier.
A background music source is connected directly to the ZPM3
and level adjustments are made using the BGM LEVEL con-
trol on the ZPM3. The background music source must be able
to supply approximately 0 dBm (0.775 VRMS) across a
600-ohm load. Use shielded cable for all talk back amplifier
connections and runs to talk back zones.
Central-Amplified Talk/Talk Back Systems with
BGM to All Unpaged Zones During Pages
A second amplifier is required in the configuration illustrated
in Figure 7, which mutes background music in the paged zone
only (without muting music at any other zones). The BGM
amplifier and paging amplifier should be of equal power.
A talk back amplifier is necessary for two-way operation.
Because of the high gain of the TBA15 talk back channel,
cross talk from the high-voltage bus of the background music
amplifier may be noticeable. To minimize the cross talk, use
the 25V tap on the BGM amplifier and reduce high-frequency
BGM material by lowering the amplifier treble setting. Use
shielded cable for all talk back amplifier connections and runs
to talk back zones. Adjust the paging and BGM volume with
the volume controls on each amplifier (the ZPM3ʼs BGM
LEVEL control is not used in this application).
Central-Amplified Talk/Talk Back Systems
with Dedicated High-Power Zones
When a system requires more than 100 watts of power,
or when one or two zones require more power than the
others, dedicated amplifiers can be installed on the out-
put side of the ZPM3 for these zones. An attenuator pad
(see Figure 8) is required between the input of the am-
plifier(s) and voltage output from the zone(s). Note that
the voltage is reduced approximately 100 times (70V AC
is reduced to 0.7V AC).
Amplified Speaker Systems and BGM to
Unpaged Zones
Systems installed as shown in Figure 9 use a one-way
speaker. Background music is muted in the paged zone
only. The background music sources in this system must
have their own level control since the ZPM3ʼs BGM Level
control is not used.
When there are more than 8 amplified speakers in the sys-
tem, a low-output impedance buffer amplifier is required to
drive the speaker load and reduce volume differences be-
tween single-zone pages and All-Call pages. The Bogen
BUFEX Buffer/Expander/Volume Control should be set high
enough to drive the speakers during an All-Call page but
not so high as to overdrive the speakerʼs input and cause
distortion. When buffering is not necessary, jumpers are
used to connect terminals PIA to POA, and PIB to POB.

Connections
Connections to the Paging System
Bridging ZPM3 Units
ZPM3 units can be linked together to provide access to more
zones. Due to the potentially large number of inputs which
may be presented to each preceding ZPM3, buffering re-
quirements may become critical and the use of buffering am-
plifiers will have to be considered. Figure 10 shows a typical
linked system.
Note that the external contact closure of the master unit (ter-
minals NOA and CMA) is used to control the status of the
next lowest ZPM3 unit. When the master controller goes off
hook, it causes all other units to also go off hook. The first
DTMF signal to the master ZPM3 connects an audio path
from the telephone system to the ZPM3 unit on the next low-
est level. The second DTMF signal instructs the lower ZPM3
unit to connect to a specific zone. This master/slave rela-
tionship can be carried on for a large number of levels, as
long as proper buffering is used.
Talk back is possible with multiple levels of ZPM3 units, but
all talk back zones should reside within the same zone on
the master ZPM3. For example, if Zone 24 is a talk back
zone, all other talk back zones should be accessed with
numbers in the twenties, since Zone 2 of the master ZPM3
is set to two-way to allow Zone 24 to be talk back. When
using multiple ZPM3ʼs, only the master ZPM3 should be set
to supply the confirmation tone; slave ZPM3 units should be
set to supply the pre-announce tone, if desired.

Features and Controls
Shift Change/Emergency Call
The ZPM3 provides either a shift change tone or Emer-
gency call (with alert tone) in all zones or in a zone group
containing up three user-selected zones. (The default
configuration sounds the tone in all zones. See section on
Field Programming to program the zone group.) This
feature overrides the standard paging features of the
ZPM3. The type of tone is user-selected and may consist
of a one-second burst or two dual-tone bursts. (See Field
Programming on page 11 to select the desired tone.)
See Figure 11 to wire the ZPM3 for the shift change
feature. See Figure 12 to wire the Emergency Call Fea-
ture. Note the use of a TPU paging amplifier MIC input.
The microphone used in this application is a desk-type
model with a push-to-talk switch. A contact closure (from a
desk microphone or push-button switch) is required to trig-
ger the Emergency Call. In the shift change application,
the contact closure from a clock energizes a relay which
disconnects any current page and activates the shift
change feature.
Night Bells
The night bell feature is triggered by either the high-volt-
age ring signal or a contact closure. Figures 1 and 3
show the connections for contact closure and high-volt-
age ring signal night bells. Use either the night ring con-
tact from the PBX or actual night line ring signal to
activate the night ringer (using both is not recom-
mended). The default configuration rings the night bell in
all zones; however, a zone group with up to three zones
can be field programmed – see section on Field Pro-
gramming to program the zone group.
All-Call Inhibit
Access to the standard All-Call function may be inhibited if
desired. This feature does not affect the Emergency Call
function. See section on Field Programming to inhibit
access to All-Call.
Privacy Beep
The privacy beep option introduces a 150ms tone every
15 seconds into the talk path of a two-way zone. Mute
contacts MT1 and MT2 close for the duration of the tone.
See section on Field Programming to enable/disable the
privacy beep option.
Volume Control
The TONE VOL control adjusts the volume of the pre-
announce, confirmation, error, and Shift Change/Emer-
gency Call tones. The NIGHT RING VOL control adjusts
the level of the night ringer tone (if enabled). The BGM
VOL control adjusts the volume of background music,
when the music source is connected to the ZPM3, as
shown in Figure 6. All controls are screwdriver-adjustable.
Mute Contacts
A set of normally closed contacts (MT1 & MT2), that go to
a normally open state whenever the the ZPM3 is
accessing a two-way zone, are provided. This is used to
operate the talk back muting function of talk back amplifiers.
External Contact Closure
A DPDT contact set (terminals NOB, NCB, CMB) is
available for operating external equipment and for use
in ground start, shift change, and Emergency Call appli-
cations. These contacts change state when the ZPM3
goes off-hook.
24/48V Talk Battery Selection
DIP Switches 1 and 2 are set to match the type of talk
battery supply that is being used. Both switches must
be set in the identical position.
Subzone Lockout
The subzone lockout switch, DIP Switch 3, must be set to
the ''O'' position when programming features through the
telephone. When placed in the ''I'' position, no additional
programming can be done.
Confirmation Tone
DIP Switch 4 turns the confirmation tone on (I) or off (O).
Pre-Announce Tone
DIP Switch 5 turns the pre-announce tone on (I) or off (O).
Talk/Talk Back Zone Selection
DIP Switches 6 through 8 on the top bank of the ZPM3
are used to the set the mode of the individual zones. Set
the respective zone DIP Switch to ''I'' for one-way zones
and ''O'' for two-way zones.

Programming Zone Groups
The ZPM3 allows for three Paging Zone Groups (Zone
Groups 1, 2, and 3), each one consisting of up to three
user-selected zones. A night bell zone group (Zone Group
4) can be programmed to ring the night bell in up to three
zones. A Shift Change/Emergency Call Zone Group (Zone
Group 5) can be programmed to sound the Shift
Change/Emergency tone in up to three zones. Use the
following procedure to program zone groups.
1. Access the ZPM3 by dialing the trunk access number or
station access number. Listen for the confirmation tone
(if enabled).
2. Press and wait for the program tone (short beep).
3. Select the zone group to be programmed by pressing
the corresponding key for paging zone
groups 1, 2, or 3, respectively, to assign zones to a
night ringer zone group (instead of sounding in all zones),
or to assign zones to a Shift Change/Emergency
Call Zone Group (instead of sounding the shift change
tone or providing Emergency All-Call with alert tone to all
zones).
4. Press the keys corresponding to the desired zones (1-3)
to reside in the zone group up to three zones (if less than
3 zones are to be included, see note below).
5. Press and wait for a short beep, then hang up.
NOTE: To enter less than 3 zones, follow step 4 above but fill the
unused zone group position with the last zone selected (i.e., to
enter zones 1 & 2, dial 1-1-2). The ZPM3 records the last three
zone selections chosen no matter how many digits were pressed
during the programming procedure. This also makes it possible
to override any incorrect zone selections made during the pro-
gramming process.
Incorrect selection of zones for a zone group can be changed
during programming, however, the zone group number must be
correctly selected from the start. If the programming procedure
is started but you do not wish to complete it, hang up. If the #
key was not pressed a second time (Step 5), none of the selec-
tions will be committed to memory. If an illegal selection is made
during the programming procedure, a beeping error tone will be
heard in the handset – the ZPM3 must be put back on-hook and
the programming process restarted. If the ZPM3 sounds an error
tone immediately after pressing the # key for the first time, check
to see that the Subzone Lockout (DIP Switch 3 is in the OFF (O)
position.

Installation
The battery backup requires four (4) AA size nickel cad-
mium (NiCd) batteries, with an amp-hour rating of 450
mAhr or higher. To install the batteries, remove the four
screws that secure the cover of the unit. Use needle nose
pliers to carefully squeeze in the locking tabs on the four
plastic standoffs that mount the PPC board. Gently pull
the board off of each of the standoffs and place it aside.
Insert the 4 batteries as shown on the battery holder.
Check that the battery clip is securely attached to the bat-
tery holder. Align the main PC board with the 4 standoffs
and carefully press the board until all 4 standoffs latch.
Replace the cover and mount the unit.
Charging
New batteries should be fully charged before using the
battery backup feature. The ZPM3 provides a constant
trickle charge which will fully charge batteries in approxi-
mately 48 hours (batteries should last 5-7 years). A green
LED illuminates to indicate that the charging system is
operative; it does not indicate the condition of the batteries.
No damage will occur to the ZPM3 or the batteries if there
should be a power outage during this initial charging
period, but the integrity of the programmed features
cannot be guaranteed. Remove all power before replac-
ing batteries. Once the batteries have been removed,
user-programmed features are erased.
NOTE: Batteries should be disconnected if the ZPM3 is to be
left unpowered for more than one day.
Resetting the Battery Backup
If for some reason, such as extended power outages, it
should become necessary to reset the ZPM3, do the fol-
lowing. Unplug the 24V power supply to remove the pri-
mary power. Locate the battery backup reset access hole
at the top left of the unit. Using a suitable screwdriver,
press the small black button next to the green LED. Plug
the power supply back in and re-program the user features.
Paging a Zone
Access the ZPM3 by dialing the trunk access number or
station access number. Listen for the confirmation tone
(if enabled). Dial the number of the zones desired (1 to 3).
Paging All Zones (All-Call)
Access the ZPM3 by dialing the trunk access number or station
access number. Listen for the confirmation tone (if enabled).
Dial (0) for All-Call.
Paging a Zone Group
Access the ZPM3 by dialing the trunk access number or
station access number. Listen for the confirmation tone (if
enabled). Dial (*) (1) for zone group 1 (*) (2) for zone group
2 or (*) (3) for zone group 3.
NOTE: Zone Groups 4 (Night Bell Zone Group) and 5 (Shift
Change/Emergency Call Zone Group) cannot be accessed
through the telephone. These groups are only activated by the
night bell and shift change/emergency call features respectively.
