Redback® A 4500B Evacuation Controller & Timer Overview
1.0 OVERVIEW
1.1 INTRODUCTION
The A 4500B is a weekly timer and Evacuation controller all housed in a convenient 1RU rack mount chassis. A total of 50
“event” switching times are available through the timing functions. Each event can be set to turn on any single day of the
week or on multiple days, from 1 sec up to 24 hours. When a timing event is activated, an MP3 audio le will be played
and output through the dual RCA line level output. There are fourteen MP3 playback options for the timing events, which
include the Bell, Prebell, Music and folders 5-15. A Micro SD card which is supplied, houses all the MP3 les to be played as
well as storing all the timing events (Note: The audio les must be in MP3 format). The timing events can be programmed via
the unit’s front buttons which is a bit cumbersome, or they can be programmed with the supplied PC software (also available
as a download from www.altronics.com.au).
The timing events can also be programmed to only trigger the Bell 24V out (and in turn the common 24V Out), with no
audio output. This is activated by setting the output to the “relay” option in the programming setup.
The Evacuation controller is designed around industry standard building emergency alert/evacuate requirements. When con-
nected to a paging system amplier, building occupants can be alerted and/or evacuated in the event of an emergency e.g.
re, gas leak, bomb scare, earthquake. Alert & Evac switches on the front of the unit are tted with safety covers to prevent
accidental operation.
The Alert, Evacuation and Bell tones and the cancel function are triggered by the front switches, or by the rear terminal
contacts for remote activation.
The Alert, Evac, Bell and Cancel functions can also be activated via remote plates or the A 4564 Paging Console.
Switched 24V DC Out connections are provided for Bell, Alert, Evac or a Common out. These contacts are for connection of
override relays in remote volume controls, warning strobes, bells etc.
The alert and evacuation tones are stored on the Micro SD card (Emergency Tones which conform to AS1670.4 are supplied)
to allow the user to provide any tones they require (Note: The audio les must be in MP3 format).
The Evacuation mode has a voice over option for the playback of an evacuation message every third cycle of the evac tone.
The voice over message is also stored on the Micro SD card and is DIP switch enabled.

2.0 SETUP GUIDE
2.1 INITIAL SETUP
For the unit to function correctly, the supplied Micro SD card must be installed and have MP3 les in each of the Alert, Evac
and Bell folders. Figure 2.1 below shows the contents of the MIcro SD Card.
NOTE: The unit will display an MP3 error message on the screen if any of the Alert, Evac and Bell folders on the Micro SD
card are left empty.
The Micro SD card should have the following folders already installed “Alert, Bell, Evac, Music, Prebell, Voice and 5-15”.
If these folders don’t exist they will have to be created.
Inside each of the Alert and Evac folders there will be a sample MP3 audio le. The alert and evac MP3 les meet the Aus-
tralian standard for evacuation tones. A library of sample MP3 les is supplied (in the #LIBRARY# folder).
NOTE: All folders except the “Prebell” and “Music” folders must have only one MP3 le installed. The “Prebell” and “Music“
folders can have unlimited MP3 les (depending on available storage) and will then randomly play the MP3 les in the folder
each time the corresponding prebell or music contact is triggered or time activated.
In order to install MP3 les onto the Micro SD card, or move the sample MP3’s to their relevant folders, the Micro SD card
will need to be connected to a PC. You will need a PC or laptop equipped with a Micro SD card reader to do this. If a Micro
SD slot is not available then the Altronics D 0371B USB Memory Card Reader or similar would be suitable (not supplied).
You will rst need to remove power from the A 4500B and then remove the Micro SD card from the front of the unit.
To remove the Micro SD card push the card in and it will eject itself.
Step by step guide to install an MP3 into it’s associated folder with a Windows based PC.
Step 1: Make sure the PC is on and card reader connected and correctly installed. Then insert the Micro SD card into the
reader.
Step 2: Go to “My Computer” or “This PC”and open the Micro SD card which is usually marked “Removable disk”.
In this case it is named “Removable disk (O:)”. Select the removable disk and then you should get a window that looks like
gure 2.1.
Fig 2.1

Redback® A 4500B Evacuation Controller & Timer
Setup
Step 3: Open the folder to change, in our example the “bell” folder, and you should get a window that looks like gure 2.2.
Fig 2.2
Step 4: You should see an MP3 le “Schoolbell3.mp3”. This MP3 le needs to be deleted and replaced by the MP3 le
you want to play when you activate the bell.
The MP3 le name is not important only that there is one MP3 le (see Note 2) in the “bell” folder. Make sure you delete
the old MP3!
Note 1: MP3 les should have the following specications for optimum performance.
128kbps, 44.1kHz, 32bit, VBR or CBR, Stereo (even better as mono).
Note 2: All folders except the “Prebell” and “Music” folders must have only one MP3 le installed. The “Prebell” and “Music”
folders can have unlimited MP3 les (depending on available storage).
Note that the new MP3 le cannot be “Read only”. To check this, right
click on the MP3 le and scroll down and select Properties, you will get a
window that looks like gure 2.3. Make sure the “Read Only” box has no
tick in it.
Fig 2.3
Repeat these steps for the other folders.
The new MP3’s are now installed on the Micro SD card, and the card can be removed from the PC following windows safe
card removal procedures. Make sure the A 4500B is OFF and insert the Micro SD card into the Micro SD card slot ; it will
click when fully inserted.
The A 4500B can now be switched back On. If all the MP3 les are OK then the unit will display the time screen. If an MP3
error message is is displayed, there is a problem with one or more of the MP3 les.

Redback® A 4500B Evacuation Controller & Timer
2.2 ALERT, EVAC AND BELL SWITCHES
The Alert, Evac and Bell switches on the front of the unit all work in momentary mode. ie. The alert tone will continue to
sound after the alert switch is momentarily pressed and the evac tone will continue to sound after the evac switch is mo-
mentarily pressed. There is an automatic alert to evac switch-over option associated with the front panel switches (refer to
section 2.8).
Note 1: The tone that is being sounded (ie alert, evac, bell) will be indicated by the illumination of the relevant front panel
indicator.
Note 2: To cancel a tone either use the remote cancel contacts or the front cancel button. Note the cancel button will need
to be depressed for 2 seconds. This is to prevent accidental cancelling of a tone.
The Alert, Evac and Bell tones are stored on the supplied Micro SD card. Separate folders are supplied on the Micro SD card
for each tone. It is up to the user to provide the MP3 les (they must be in MP3 format) for each of the tones. A library of
sample MP3 les is supplied (in the #LIBRARY# folder). See section 2.1 for more details.
NOTE: The unit will display an MP3 error message on the screen if any of the folders on the Micro SD card are left empty.
I.e. the Alert, Bell, Evac, Music, Prebell and Voice folders must all have an MP3 le inside.
Once these Alert, Evac and Bell outputs are activated, the corresponding 24V switched outputs will become active (refer to
section 2.6 for more details)
2.3 PROGRAMMING THE TIMING EVENTS USING THE FRONT BUTTONS
If the unit starts up correctly and no error messages are displayed, the model number will be displayed briey before the
current time is shown. See Fig 2.4.
Fig 2.4
If this screen doesn’t appear and instead an MP3 error message is displayed, then either the Micro SD card is not inserted
correctly or there is a missing MP3 le.
NOTE: The unit will display an MP3 error message on the screen if any of the folders on the Micro SD card are left empty.
I.e. the Alert, Bell, Evac, Music, Prebell and Voice folders must all have an MP3 le inside.
The main screen (Current Time Screen) shown in Fig 2.5 displays the current time and day, and the next programmed event.
Fig 2.5
When this screen is displayed the unit is running in “AUTO MODE” and therefore all outputs will work as programmed.
However if the unit is in any of the sub menu’s (Menu Mode) the unit will no longer respond to any event that has been
programmed to occur. On exiting the menu, the timer will check all programmed events and update the status of the output
zones.
In order to set up the timer, the station (or event) times will need to be programmed. This can be achevied by using the but-
tons on the front of the unit or via the PC software (supplied on the Micro SD card) see section 2.4 for more details.
PROGRAMMING THE TIMING EVENTS USING THE FRONT BUTTONS
There are ve buttons on the front of the timer which are used to program the unit and navigate the various menus.
SPECIAL NOTE ABOUT “AUTO MODE” OPERATION
If the timer is not displaying the main clock screen, where the time is changing, the unit is not running in
“Auto Mode”. This means it will not be checking any of the programmed events and hence will not activate
any outputs automatically.
Essentially this means that as soon as the Menu button is pressed the unit is no longer in “Auto Mode”.
Make sure to return to the main screen by exiting all menu’s when not making changes.

Once again, use the up and down buttons to set the hour, minutes and seconds and press enter when nished. Once the
period has been set, the desired output MP3 for this event is to be set using the MP3 output screen (See g 2.10).
Fig 2.10
The MP3 output defaults to Prebell. Scroll through the other options by using the up and down buttons. The MP3 output
can be set to Prebell, Bell, Music, No MP3 or the output can be disabled. These MP3 outputs correspond to the MP3 audio
les located in the Prebell, Bell and Music folders on the Micro SD card.
RELAY OUTPUT CONFIGURATION
The 24V switched outputs associated with the Prebell, Bell and Music folders are as follows.
When the Bell output is active the Bell 24V output and Common 24V output will become active.
When the Prebell and Music outputs are active the the Common 24V output only will become active.
The NO MP3 option will activate the Bell and Common 24V output, but no audio le will be played.
Once the desired output for the event has been set, press the enter button to move to the next screen (See g 2.11). This
is where the days of the week this event will occur are entered. The top right line of text refers to the days of the week,
Monday through to Sunday. The line of text below this sets each day “ON” or “OFF”. Use the up and down buttons to set
the day to Y for “ON” and N for “OFF”.
Fig 2.11
Once the days of the week are set, press the enter button to conrm and be returned to the main menu. Repeat this process
for any other events to be programmed.
This process of entering the events can be quite time consuming. An easier method of entering this information is by using
the supplied PC software which is provided on the Micro SD card (see section 2.4).
2.4 PROGRAMMING THE TIMING EVENTS USING THE SUPPLIED PC SOFTWARE
The PC software is provided on the units’ Micro SD Card and is called “RedbackA4500TimerProgrammer”.
In order to access the program, the Micro SD card will need to be connected to a PC. You will need a PC or laptop equipped
with an Micro SD card reader to do this. If an Micro SD slot is not available then the Altronics D 0371B USB Memory Card
Reader or similar would be suitable (not supplied).
You will rst need to remove power from the A 4500B and then remove the Micro SD card from the rear of the unit.
To remove the Micro SD card push the card in and it will eject itself.
Make sure the PC is on and card reader connected and correctly installed. Then insert the Micro SD card into the reader.
Go to “My Computer” or “This PC” and open the Micro SD card which is usually marked “Removable disk”.
In this case it is named “Removable disk (F:)”. Select the removable disk and then you should get a window that looks like
gure 2.12.

An event can now be programmed from this window. A description of the event can be added if desired such as Pre bell,
Morning Tea etc. The start time, nish time, output and days of the week can all be entered. Selecting the days of the week
is as simple as clicking the desired days or selecting the weekdays box.
The latest PC software now includes up to fourteen MP3 output folders, which include Bell, Prebell, Music and output folders
5 - 15. The “Relay Only” Output option only activates the Bell 24V DC output (see section 2.11).
NOTE: All folders except the “Prebell” and “Music” folders must have only one MP3 le installed. The “Prebell” and
“Music“ folders can have unlimited MP3 les (depending on available storage) and will then randomly play the MP3 les in
the folder each time the corresponding prebell or music contact is triggered or time activated.
Figure 2.14 shown below illustrates an example. This event is the prebell for a primary school and is programmed to activate
5 minutes before the rst bell of the day.
A music track will be played at 8:55:00 and continue to play until 08:59:59.

Switch 5-8 Not Used
Fig 2.24
2.11 24V OUTPUT CONNECTIONS
These contacts can be used for connection of override relays in remote volume controls, or strobes for unusually noisy
environments. An override relay is necessary where attenuators are used so that the alert tone, evac tone or message is
broadcast at full volume regardless of the volume setting on the individual volume control (attenuator).
Alert/Evac 24V Out:
These contacts are for switched 24V outputs whenever the alert or evac tones are activated. These may be used to run
external systems such as strobes in unusually noisy environments, or override relays in remote volume controls.
When this output becomes active, 24V will appear between the N/O contact and the GND contact. When this output is not
active 24V will appear between the N/C contact and the GND.
Bell 24V Out:
These contacts are for switched 24V outputs whenever the Bell or Relay Only (No MP3 option) are activated These contacts
are for operating an external relay used to operate something like a lunch bell etc.
When this output becomes active, 24V will appear between the N/O contact and the GND contact. When this output is not
active 24V will appear between the N/C contact and the GND.
Common 24V Out:
These contacts are for switched 24V outputs whenever the Alert, Evac, Bell, Prebell or Relay Only (No MP3 option) tones are
activated. When this output becomes active, 24V will appear between the N/O contact and the GND contact. When this
output is not active 24V will appear between the N/C contact and the GND.

3.0 REMOTE WALL PLATES
There are a number of remote wall plates which can be connected to the A 4500B for remote triggering of the Alert, Evac-
uation and Bell tones and for remotely cancelling any tones which may be active.
3.1 A 2078B and A 2081 Remote Plates
A 2078B A 2081
The A 2078B wall plate provides a remote means of triggering the Alert and Evacuation tones and the cancel function.
While the A 2081 wall plate provides a remote means of triggering the Alert, Evacuation and Bell tones and the cancel
function. Connection from the A 2078B is made to the A 4500B via a minimum of 6 wires as shown in Fig 3.1A. Connec-
tion is made from the A 2081 to the A 4500B via a minimum of 8 wires as shown in Fig 3.1B.
If standard Cat5 cable is used for the wiring, the plate can be located up to 30m away from the main unit. This can be
increased to 100m away using heavier guage cable, which reduces the voltage drop across this distance and ensures the
switch leds illuminate.
The Alert/Evac/Chime/Cancel switches on the wall plate are connected to the corresponding contacts on the rear of the A
4500B. While the Alert, Evac and Bell LEDs on the wall plate are connected to the Alert,Evac and Bell 24V outputs of the A
4500B. The cancel LED is not connected. A mimimum of six wires can be used on the A 2078B if the ground connections
of the Alert and Evac 24V outputs and the Alert/Evac and cancel switch grounds are linked together (see Fig 3.1B).
A mimimum of eight wires can be used on the A 2081 if the ground connections of the Alert,Evac and Bell 24V outputs
and the Alert/Evac/Chime and cancel switch grounds are linked together (see Fig 3.1B).
