2.0 SETUP GUIDE

This is intended to be a quick setup for a minimal install. Section 3.0 will build on the initial setup and cover the installa-
tion of peripheral connections and more in depth detail on programming the unit. In this basic configuration we will use
a setup in a bar as an example. The install requires 2 audio sources, a tuner and a dvd player. This audio will be fed to 4
different zones, the main bar, the beer garden, the restaurant, and the kitchen. All adjustments will be made from the
front panel of the A 4480B.
A programming template in PDF format is available to download from the Altronics website. This allows you to map your
inputs, outputs, zone names, source names and presets before you commence programming. A printed copy is located at
the end of operating manual (see section 9.0).
2.1 ALERT/EVACUATION/CHIME MODULE
The A 4573 module generates pre announcement chimes and alert and evacuation tones.
Separate volume controls are included for adjustment of the alert/evac tone level, the chime level and the message
voice-over level. The chime and alert/evac tones are triggered by closing contacts via a five way euro block. These triggers
can be set to momentary or alternate action by on board DIP switches.
Chimes included on the module include pre announcement, Ding Dong, repeating Bing and repeating Bong. All of these
are DIP switch selectable.
The module is also fitted with a switch over option which changes the evacuation tone from the Alert tone to the
Evacuation tone after a set time. This can be adjusted from 30 seconds to 270 seconds in 30 second increments or it can
be switched off altogether.
A microphone has been included which is used to record an emergency voice over message if required. This message can
be turned on via DIP switches, and will play twice after the evacuation tone has repeated four times.
