The A 4500 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 file will be
played and output through the dual RCA line level output. There are
three MP3 playback options for the timing events, which include the
Bell, Prebell and a Music option. An SD card which is supplied, houses
all the MP3 files to be played as well as storing all the timing events
(Note: The audio files must be in MP3 format). The timing events can be
programmed via the units front buttons which is a bit cumbersome, or
they can be programmed with the supplied PC software (also available as a
download).
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 connected to a
paging system amplifier, building occupants can be alerted and/or
evacuated in the event of an emergency e.g. fire, gas leak, bomb scare,
earthquake. Alert &Evac switches on the front of the unit are
fitted 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. 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 SD card (Emergency
Tones which conform to AS1670.4 are supplied) to allow the user to
provide any tones they require (Note: The audio files 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 SD card and is DIP switch enabled.

Programming the Timing Events The timing events
can be programmed via the units front buttons which is a bit
cumbersome, or they can be programmed with the supplied PC software
(Screen shots shown below).
Programming the A 4500 with the software is very simple.
Open the program by double clicking the Redback A 4500 Timer Programmer.exe file. The program will appear as shown below.
If the program doesn't run then the .NET Framework might need to be
updated on your PC. This must be updated to the .NET Framework 4,
available on the microsoft website.
