PA Matthews Audio DELUXE SCHOOL PA, INTERCOM SYSTEMS Operating Manual

DELUXE SCHOOL PA

AND INTERCOM SYSTEMS

OPERATING MANUAL

Version 2.4—2014

Introduction

Congratulations. Your investment in a new PA Matthews Audio integrated school communications system will now give

your school years and years of trouble free operation. If your system is a completely new install then this booklet will
explain all the equipment items and how they work. However if your system was a renovation of an older one and still
contains some older components (such as an older PA amplifier or music playout equipment) then the operation
principles are the same but the actual photographs here may not always be the same as your system.

The photographs in this booklet are taken from a “wall mount” system. If you have a “rack mount” system then the

principles are the same but the actual switches may be in different locations to those shown on the photographs.

System Overview

Your system consists of two totally separate equipments sharing common cabling. These are the PA system (used for

bells, line up music, evacuation, lock down and voice paging—usually over the whole school campus) and the
Intercom system (used for contact and communication between the office and individual class rooms). A failure in one
usually does not normally affect the other unless someone has cut through wires somewhere!

The cabling for your system is completely independent of any existing telephone, power or computer data systems in

your school—although in most cases our system cabling will often run in common conduits, ducts or looms, possibly

sharing space with these other cables. Cabling alterations or repairs can normally be made by any suitably qualified
electrical contractor with telephone or data system experience or you can send us an email (recommended) if there is
any confusion and we can advise on alterations or repairs.

A full set of cable records, together with a map showing approximate cable routes and details is kept on site inside the

intercom termination box. Alternatively you can email us and we’ll email you or your contractor a PDF copy free of
charge.

Instruction Booklet

This booklet is divided into three sections:

1.) Quick Guide

This section contains a series of simple step by step instructions for things that you are likely to need to do with the

system on a regular basis. In most cases the answer to your question about using the system can be found in here.

2.) Detailed Instructions

This section has all the finer details about configuring the system and it’s components. These are things you won’t

normally have to touch in daily use but you might need to look at when you wish to change the way the system works.
For example changing your bell times or changing the music or tones on the system.

3.) Troubleshooting Guide & Service Contact

This section contains a list of possible problems you may encounter with the system and suggests tests you should

carry out on the system yourself before calling for service. This way if a service call is required, you can give us
accurate information on what’s wrong with the system and we can make sure you get back on the air as soon as
possible.

Quick Guide—Page 3

1.1) How to over ride the bell timer or Ring Bell Manually:

1.2) Turning OFF the system for Holidays;

1.3) Using the Paging Microphone;

1.4) Using the Evacuate and Alert (Lock down) tones;

1.5) Change time for Daylight Savings;

1.6) Using / Testing Line Up Music;

To ring the bell manually just push

the RED “Manual Bell” button. The
bell will continue to ring for as long
as you remain pushing the button.

To stop the bell ringing automatically

(for example, for a school day where
bell times have changed) switch
OFF the “Auto Bell” switch and ring

the bell manually for that day only.
Don’t forget to put it back ON
afterwards.

Your timer will have been programmed to exclude Saturdays and Sundays

so the system can be left ON over weekends. However for school holidays
the system should be turned OFF so as to minimize disruption to
neighbours. Just switch OFF the power switch to the bottom right hand
side of the amplifier and switch it back ON again when you return after the
break. Your bell times and settings will be preserved during this process.

To use the paging microphone push DOWN on the toggle, wait for the tone

then make your announcement. Do NOT switch the toggle UP as the
switch will then remain ON and you risk the microphone being left on after
you have finished.

EVACUATE is the standard emergency “Whoop whoop” sound and is used to evacuate the

school. In event of an emergency it should be switched ON and left there until the your
authorised person gives permission to switch it off.

ALERT is a “Beep Beep” sound that fades up slowly and should be used for about 30

seconds ~ 1 minute to signify LOCK DOWN conditions in the school. Cancellation of a
lockdown should be done by making an announcement over the microphone.

Regular Drills (one per term) should be held in the school to familiarise staff and students

with these tones. PA Matthews Audio also strongly recommend these tones be briefly
TESTED every month (as a minimum) to ensure they are operational in the case of an
emergency. This is normally done after school hours and after an announcement is made
“attention, this is a test only” or similar.

The timer does NOT automatically adjust for daylight savings. This needs

to be done MANUALLY using the following process;

1.) Open the timer lid and press “Menu” ONCE.

2.) Press “” button ONCE.

3.) Press “OK” button TWICE.

4.) Press “” or “⊳” buttons to select correct hour.

5.) Press “OK”

6.) Change Minutes (if required, otherwise skip this step)

7.) Press “OK”.
You’re done!

To use Line Up Music, switch the “Line Up Music” switch DOWN (ON).
To isolate, switch OFF.

To test the volume level of the line up music, switch the “Music Test” switch on to MANUAL
and then switch it back to AUTO when testing is complete.

Quick Guide—Page 4

1.7) Selecting individual speaker zones:

1.8) Adjusting the Volume Controls;

1.9) Using the TCM Intercom (Where installed);

Each button on the intercom corresponds to a handset installed

in a class room. The labels next to the buttons will match up
with a school room map which will have been securely glued to
the wall next to the intercom unit by the installing contractor.

To make a call:

Lift the handset and push the button for the room you wish to

call. You will hear a ring tone until the called party answers.

To receive a call;

When the calling party lifts the handset in the room the master will ring and the light for the calling party will

light. Lift the handset and push the button to talk.

If two or more callers call the master at the same time then each calling room’s light will illuminate. When you

select which one to speak to, any other callers will then receive a busy tone until you complete the first call. If
they remain on the line the unit will “camp on” the next caller and allow you to answer the next call once the
first is finished.

To transfer a call;

Although not recommended, it is possible to manually transfer calls from one room to the next.
a.) Party A calls office.
b.) Office answers call in the normal way.
c.) Party A asks to be transferred to Party B.
d.) Office asks Party A to hold.
e.) Office then presses button for Party B.
f.) Party A will hear busy tone while office calls Party B.
g.) When party B answers, tell them they have a call and press “Transfer” button.
h.) Press Party “A” station button.
i.) The three conversations are now joined. A three way conversation can take place.
j.) When the office hangs up, Party A and Party B may continue to talk
k.) System will clear when both parties hang up.

Note : PA Matthews Audio recommends that the intercom unit be switched off and unplugged from the
main termination box during school holidays.

On the amplifier there are six buttons (pictured). Above this the installing

contractor will have written a list of which speakers are controlled by each zone
switch.

Normally the “ALL” switch must be left pushed IN so that the bell and other critical

tones are heard clearly throughout the whole school.

However you may isolate zones if necessary. An example might be to make an

announcement on the inside speakers only (during a lock down) or to run a test
using the office speakers without disturbing the rest of the school.

To do this simply press OUT the “ALL” switch and then press IN the switch(es) for

the zones you wish to use.

Remember to press IN the “ALL” switch once you have finished so that the

bell and critical tones will be heard normally afterwards.

The installing contractor will have marked white arrows on the volume controls

when your system was installed. These are “Ideal starting points” for your system.
You can increase or decrease the volume of either the Paging Microphone or the
System Tones. The other (unused) channels should always be left OFF.

Remember that adjusting these controls will affect the volume level of the entire

system.

The Bell, Tones and Music are all controlled by one volume control. If you find that

the (line up) music is too loud we recommend that you re—record the relevant
MP3 music file at a reduced level and re load it onto the system, as turning down
the “Tones” volume control too far may sounds like the Bell and Evacuation tones
too quiet to hear clearly over the whole school.

2.1) Theben TR622top2 Bell Timer

The timer controls the BELL sound and the LINE UP MUSIC.

Bell : Channel 1 controls the BELL. Each bell is programmed as a

PULSE with a normal duration of 10 seconds. Each
programmed time is written in to a day (usually Monday or
Day 1) and then “Copied” and added to Days 2 to 5. Days
6 and 7 (Weekend) are then skipped before the time is
saved into memory and the next time is then programmed.

Music : Channel 2 controls the LINE UP MUSIC. Each music play is

programmed as a PULSE with a normal duration of 2

minutes. Example : Music starts at 10:58am and 2 minutes

later finishes at 11am. A bell time set for 11am then rings the

bell.

Reset : It is possible to modify or delete individual times. However

we strongly recommend that for more complex changes
(such as changing a complete recess or lunch start and
finish time which may involve changing up to six or seven
individual events) that you instead perform a FULL RESET
of the timer and reprogram it from scratch. This makes errors far less likely, and errors can some times result
in the bell or music coming on and / or staying on at weird times (such as midnight) resulting in significant

problems.

Lists : Before programming we strongly recommend you write out ALL your proposed bell and music times on a
weekly schedule, even showing times that are the same on each day. This will make programming easier
and reduce the chance of making mistakes.

Each panel below shows a step by step procedure to program, modify, delete or clear bell times. Text shown in

PURPLE indicates what you will see on the timer display for each step.

2.2)

Using the Obelisk card Programmer (if supplied).

Overview :

The OBELISK top2 programmer
allows you to store, recall, back up
and easily program your bell timer
using a computer screen interface.

Many people find this easier than
using the menu driven program on
the timer itself as it displays the
complete weekly program on one
screen. This option is recommended
for schools that change their bell times regularly or need this
flexibility.

The programmer comes with an extra OBELISK card. Many
schools use this to establish a “summer” and “winter” set of
times, program one card with each and then simply load the
relevant times into the timer as the seasons change.

On the next page is an example of the Theben software
screen showing bell times programmed into Channel 1.

Using the OBELISK storage card

The OBELISK card is used to transfer programs from
the USB computer programmer to the timer (see next
page).

It is also used for back up storage of times in the event
that something goes wrong with the timer settings and
the times need to be restored to their previous settings.

When your install contractor initially programmed your timer, a copy
of the initial program was saved on the obelisk card. Even if you
don’t use or even have an Obelisk computer programmer (which is
an option some schools don’t choose) you can still use the Obelisk
card supplied with your timer to restore settings. This is especially
useful if you have attempted to make changes to the timer and made
a mistake and now don’t know where the mistake is.

The Obelisk card is stored in the lid of the timer. It only goes into the
slot one way. Be GENTLE inserting the card. Do NOT force the card
into the slot. If it refuses to plug in, gently move it around up and
down until it plugs in securely to the slot.

To LOAD settings from Obelisk card.

1.) Insert obelisk card (COPY OBELISK—TIME SWITCH)

2.) Press OK (OVERWRITE?)

3.) Press OK (Screen shows “COPY” then “END”)

4.) Press OK (REMOVE OBELISK)

5.) Remove Obelisk.

To SAVE settings TO Obelisk Card

1.) Insert obelisk card (COPY OBELISK—TIME SWITCH)

2.) Press  Once. (COPY TIME SWITCH—OBELISK)

3.) Press OK (OVERWRITE?)

4.) Press OK (Screen shows “COPY” then “END”)

5.) Press OK (REMOVE OBELISK)

6.) Remove Obelisk.

To completely erase all settings from

BOTH CHANNELS of timer and start again

1.) Press MENU & Press OK

2.) Press  3 times (DELETE) & Press OK

3.) Press  3 times (DELETE ALL) & Press OK (DELETE C1)

4.) Press OK (CONFIRM) then press OK again (DELETED)

5.) Press OK Once (SWITCH)

6.) Press  3 times (DELETE ALL) & Press OK (DELETE C1)

7.) Press  ONCE (DELETE C2)

8.) Press OK (CONFIRM) then press OK again (DELETED)

9.) Press MENU Twice to get back to start.

To modify or delete a Bell time :

1.) Press MENU, then press OK.

2.) Press  button TWICE to Modify, THREE times to delete

3.) Press OK Once.

3.) Press  button ONCE (“PULSE”)

4.) Press OK TWICE and first time will be displayed.

5.) Press  to step to next time or OK to modify.

6.) Follow screen prompts to make changes, using
OK to step through each one.

7.) Press MENU TWICE when finished to get out.

To Modify Music Times :

1.) Press MENU, then press OK.

2.) Press  button TWICE (“MODIFY”)

3.) Press OK ONCE .

4.) Press  button ONCE (“PULSE”)

5.) Press OK once. (“Channel C1”)

6.) Press  button ONCE (“Channel C2”)

7.) Press OK and first MUSIC time will be displayed.

5.) Press  to step to next time or OK to modify.

6.) Follow screen prompts to make changes, using
OK to step through each one.

7.) Press MENU TWICE when finished to get out.

PERFORMING A GLOBAL RESET

A Global reset is recommended if the timer has failed or there is
an unknown faulty time or mode programmed into the timer
caused by unauthorised persons mucking about with it.

A Global reset should be performed if there have been any
reports of the timer being triggered “out of hours” (eg. At night or
on weekends or bells / music running for long periods, etc).

A Global Reset will erase ALL settings AND the current time
and date and set the timer back to it’s initial factory settings.

1.) Press down and hold ALL FOUR BUTTONS on the
front of the unit SIMULTANEOUSLY for 3 seconds.

(flashing “ENGLISH”)

2.) Press OK ONCE. (“Retain Programs”)

3.) Press  ONCE (“Delete Programs”)

4.) Press OK TWICE (“Deleting Programs”)

5.) You will now need to follow the prompts and reset the date
and time. Make sure accurate time is used
(dial 1194 on any phone).

6.) Once the minutes and seconds are set, the timer will then
prompt you for “NO Su/Wi”. # note below

7.) Press OK ONCE to complete.

8.) You can now either use the OBELISK card to restore your
programs or reprogram the timer from scratch
knowing that any possible errors have been deleted.

# Note : No Summer / Winter rule on this timer should be set in
Australia as the timer follows Northern Hemisphere daylight
savings rules which are the reverse of those used in Australia.

Detailed Instructions—Page 7

2.2) Using the Obelisk card Programmer (continued).

Using the OBELISK top2 :

1.) Install the program on the CD to your computer and open the program. Click on “Termina top2” and then select
“tr622top2” and then “OK”.

2.) Connect the programmer to a free USB slot.

3.) Insert the OBELISK card from your timer (it will have been programmed with a back up set of your bell times by our
system installer when your system was commissioned).

4.) Click on the “read obelisk” button at the top of the screen (it’s just below the “help” menu, with a red arrow). The
computer will load the times off the card and onto your screen.

5.) You can now make changes and save them back to your card and thence to your timer. We recommend you also
make a back up of the times to both your computer AND the new OBELISK card as well.

Important things to remember:

The OBELISK program contains a comprehensive HELP file which is found simply by clicking “help” at the top left end
of the menu bar.

Note that when opening the program make sure you select “tr622top2” as your timer, otherwise the system will not
program the OBELISK card correctly.

Remember that “Channel 1” is the timer channel that controls your BELLS. ALL times entered into Channel 1 MUST be
PULSE TIMES usually of ten seconds duration. If you fail to do this properly the bell will get “stuck on” and ring

endlessly until you turn it off.

“Channel 2” is the music channel. This channel is programmed the same as for the BELL channel but the PULSE
TIMES are usually of 2 minutes duration. Do not programme music times for longer than 3 minutes as this will likely

generate noise complaints both from residents around the school and from within the school itself.

We strongly recommend you keep one OBELISK card (usually the one that came with the timer and was programmed
by our staff when the system was commissioned) as a BACKUP and do not write to it. Instead, write your modified
programs to the NEW card and thence load them onto the timer. That way if you make a mistake you can reload the old
times easily while you sort out what went wrong.

Detailed Instructions—Page 8

2.3) Changing the audio files on the MP3 Player.

Overview :

The A1741 unit plays MP3 files on demand as controlled
by the PA system timer and control box. Each file is
placed in a specific folder.

The name of the file is not important. Only the folder in

which the file is placed matters.

For example : When the “line up music” starts (C2 timer
channel), the system will look for whatever file is located in “trig2”
and start playing it. When the timer switches off again, the playout
will stop. If you want to change the line up music, simply change

the file in the “trig2” folder on the SD card.

The “alert” and “pre announce chime” files should NOT be
changed as these are a specific length, and changing them may
prevent the system from working properly.

Create Multiple SD Cards:

You can easily change your play out files by simply preparing
multiple SD cards and then changing the card in the play out box
say, each morning.

To prepare an additional SD card first get the existing card out of
the unit. Create a new directory on your computer and then copy
all the directories off the SD card to the directory on your
computer.

Then insert the new SD card in your computer and copy the
directories from your computer onto the new SD card so it is
identical to the existing one.

Now you can easily and safely change the data on either SD
card.

Changing files:

The most commonly changed file on your system is likely to be
“trig2” (Line up Music) which is normally 2 mins long. However
many schools also change the Bell (trig1), often to a recording
of their own school yard bell or similar.

Wet Weather (trig3) can also be changed. “trig4” is undefined so you can use it for any purpose such as a special
message for assemblies etc. We advise against changing the “evac” file however some schools change it to include
voice announcements to assist with school evacuation such as directing people where to go, etc.

Volume Levels:

Please note that the volume level of ALL the files is controlled by a single “tones and music” knob on the amplifier (ref
page 4). Care should be taken when loading any alternative files to make sure they are not too soft or loud.

The Bell (trig1) should be recorded as LOUD AS POSSIBLE so everyone hears it clearly.
The LINE UP MUSIC (trig2) should be recorded on average about 10dB quieter than the other sounds. Because this file
runs longer, it is likely to become a problem both for school staff and for your neighbours if it is repeatedly played too
loud. We recommend you adjust the overall level of music files by using an “audio editor” program such as Adobe
Audition or Audacity to recode your sound file before saving it onto the SD card.

The Alert and Evacuate files have been preset at a reduced level when your system was installed. The last thing you
need when evacuating a school is a siren blowing your head off when you’re trying to move kids about and mark rolls!

To Remove / Insert SD Card

1.) Push on card , it will then pop out.

2.) Remove card

3.) Push back in until “click” and leave.


