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 file 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 files to be played as well as storing all
the timing events (Note: MP3 files should have the following
specifications for optimum performance. 128kbps, 44.1kHz, 32bit, VBR or
CBR, stereo or mono).
The timing events can be programmed via the units front buttons, 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 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. Provision for
connection to A 4564 paging console for emergency paging only and
remote activation of alert/evac and chime functions.
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 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 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 micro SD card and is DIP switch enabled.
