PAGE / DOORBELL MODULE

Note: If the Panasonic Doorphone is the trigger source, it must be

connected exactly as shown in the diagram. If the connections are

reversed or if they are disconnected, the PDM doorbell chime will

sound continuously. If the power to the Panasonic phone system is

interrupted while the PDM and MRX/PX-600 remain powered, the

doorbell chime will also sound continuously.

PAGING

The PDM has two audio inputs designed to work with audio signals

with a maximum amplitude of approximately 1 volt peak to peak. The

signals applied to the two inputs are combined in the PDM and

routed to the AUDIO OUT of the PDM.

The PDM monitors the presence of the audio input signals and

generates a mute signal when the audio signal level exceeds a

predetermined threshold. This threshold is user-adjustable by

setting a trim pot (R42) located inside the PDM. The minimum

threshold is at the full counterclockwise rotation and the maximum

threshold is at the full clockwise rotation. The PDM is shipped from

the factory with the threshold set in the middle of its range, which

should be acceptable for most applications.

Once the mute signal is generated, it will continue for 3 to 4 seconds

after the audio signal falls below the detector threshold. This is

intended to keep the MRX/PX-600 in the page mode during brief

pauses in the page audio.

MRX PAGING SETUP

The PDM must be used with MRXs equipped with V2.xx software or

greater. Below is an excerpt from the V2.xx Software Guide for the

Paging Setup. All selections and changes are made by pressing the

TUNE UP/DOWN buttons, which in turn move a highlight bar up and

down or change an alphanumeric value. Press STORE to confirm

the selection.

❖ Enter Programming Mode by pressing PRESET 1 and MUTE.

❖ Select PAGING SETUP. Press STORE.

❖ PAGE IF ZONE OFF? Select Zone Number. Press STORE.

❖ Select YES or NO. Press STORE.

❖ Repeat for each zone until your selections are complete. Then

highlight -EXIT- and Press STORE.

❖ PAGE IF ZONE ON? Select Zone Number. Press STORE.

❖ Select YES or NO. Press STORE.

❖ Repeat for each zone until your selections are complete, then

highlight -EXIT- and press STORE.

❖ PAGE ZONE VOLUME - Select the volume the page or

doorchime will play regardless of what the correct volume level

of the zone is. Be advised that the output of the PDM is

somewhat higher than other sources, and you may want to

select conservative levels. The default as of V2.3 = 16.

INTRODUCTION

The Page/Doorbell Module (PDM) is used to generate doorbell

chimes and/or route page audio through selected zones in an MRX/

PX-600 installation. The PDM generates two independently trig-

gered doorbell chimes and has two page audio inputs. The doorbell

chimes and the page audio input signals are routed to the MRX/

PX-600 AUDIO PAGE INPUT. When the PDM detects presence of

either a doorbell chime or page audio, it generates a mute signal. It

then feeds this signal to the MRX/PX-600 MUTE INPUT. Under

software control in the MRX/PX-600, this signal causes the MRX/PX-

600 to switch to the AUDIO PAGE INPUT in selected zones and to

output the AUDIO PAGE INPUT signal at pre-defined volumes.

Each zone in the MRX/PX-600 may be programmed to allow the

AUDIO PAGE INPUT signal to play when the zone is off, and/or when

the zone is on, or not at all. Additionally, the volume of the signal is

programmable for each zone independent of the maximum, current,

or turn on volume.

CONNECTING THE PDM

Power to the PDM is supplied by a 12 VDC, 300 mA adapter which

is provided with the unit. Plug the 3.5 mm plug of this adapter into

the jack marked “12 VDC”. This adapter

must

be plugged into an

unswitched outlet.

Connect the AUDIO OUT of the PDM to the AUDIO PAGE INPUT of

the MRX using one of the two 6 foot, 3.5 mm plug to 3.5 mm plug

cables provided with the unit. Connect the AUDIO OUT of the PDM

to the AUDIO PAGE INPUT of the PX-600 using the 3.5 mm plug to

RCA cable provided with the unit.

Connect the MUTE OUT of the PDM to the MUTE INPUT of the MRX/

PX-600 using the other 6 foot 3.5 mm plug to 3.5 mm plug cable.

Connect the doorbell chime trigger inputs at the removable screw

terminal block. The trigger inputs for DOOR 1 are terminals 1 and 2,

and the trigger inputs for DOOR 2 are terminals 3 and 4. The terminal

block will accept 18-22 AWG wire.

Connect the Page audio signals to the PDM via the 3.5 mm mono

jacks labeled AUDIO IN 1 and AUDIO IN 2.

DOORBELL CHIMES

The PDM generates two independently triggered doorbell chimes.

Each doorbell chime can be configured for 1, 2, or 3 chimes. Header

#3 is used to configure door 1 and header #4 is used to configure

door 2. See Connections Diagram for jumper settings. The two

doorbell chimes may each be triggered in one of three ways: by

contact closure, by a 10-24V AC/DC voltage, or by the output of a

Panasonic Doorphone (Model KX-T30865). There are two headers

(H1 and H2) inside the PDM, programmed with shunt jumpers, that

determine to which trigger type each doorbell chime of the PDM

responds. The accompanying diagram shows the shunt jumper

locations and the trigger connections for each trigger type. The PDM

is shipped from the factory with both doors configured to respond to

contact closures. Door 1 is configured for 2 chimes and door 2 for

3 chimes.

PX-600 PAGING SETUP

Programming Instructions:

❖ Enter programming mode by pressing PGM on the programmer.

❖ Select PAGING SETUP. Press ENTER.

❖ The first screen will say PAGE IF ZONE OFF. All zones will be

listed with the default choice of YES. If you wish to set up any

zone so that it will not receive paging/doorchime signals when

off, select the zone to change and press ENTER.

❖ Use the ▲ ▼ buttons to select NO. Press ENTER.

❖ Repeat for any zone you wish to exclude from receiving paging/

doorchime signals when off.

❖ Press ENTER while the highlighter is on —EXIT—.

❖ The next screen will say, PAGE IF ZONE ON. The default

choice is YES for each zone. If you wish to set up any zone so

that it will not receive paging or doorchimes when on, select the

zone to change and press ENTER.

❖ Use the ▲ ▼ buttons to select NO. Press ENTER.

❖ Repeat for any zone you wish to exclude from paging/doorchime

signals when on.

❖ Press ENTER while the highlighter is on —EXIT—.

❖ The next screen will say PAGE ZONE VOLUME. Set the volume

at which the page or doorchime is to be played. This volume is

independent of the volume at which the zone may be operating.

The default volume setting is 16.

❖ Select zone number. Press ENTER.

❖ Select desired volume. Press ENTER.

❖ Repeat for each zone and then press ENTER while the highlighter

is on — EXIT—.

CAVEATS

Because there is only one AUDIO PAGE INPUT and one MUTE

INPUT on the MRX/PX-600, it is not possible to distinguish between

the two doorbell chimes, or between the two PDM AUDIO INPUTS,

or between the doorbell chimes and the page audio. This means that

you can’t split the doorbell chimes and/or the page audio among the

zones.

When the PDM is used with the Panasonic Doorphone, failure of the

connection to the Doorphone or loss of power to the phone system

will cause the PDM to chime continuously. This is because the

signals generated by the Panasonic Doorphone in response to

pressing the Doorphone’s button are the same as the signals that are

present with a loss of connection or power. If you are using the PDM

with a Panasonic Doorphone as a trigger, please keep this in mind

when designing the installation.

If you wish to use the PDM with the door box of a telephone system

other than Panasonic, please contact our Technical Support Depart-

ment for further information.
