Operating Manual
A 4573 Alert/Evac Module with Multiple Chimes
Redback® Proudly Made In Australia
Overview
The A 4573 module generates pre announcement chimes and alert and evacuation tones for selected Redback® products.
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 ve 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 tted 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.
Important Note:
The evacuation tone for this device conforms to re evacuation standards AS1670.4.2004
The evacuation tone (temporal pattern) conforms to international standards.
The A 4573 module is compatible with the following Redback ® products.

Triggering the tones
The unit is triggered by closing the contacts on the 5 way pluggable header. There are four different trigger inputs as
shown in Fig 2.
Evac tone - triggered by a closed contact between EV (alert tone) and GND (ground).
Alert tone - triggered by a closed contact between AL (alert tone) and GND (ground).
Chime 2 - triggered by a closed contact between CH2 (chime 2) and GND (ground).
Chime 1/Cancel - triggered by a closed contact between CH1/CAN (chime 1/cancel) and GND (ground).
The alert and evac triggers can be set to momentary or latched action. In momentary operation the alert or evac tones will
operate only while the trigger is activated. In latched operation the tones will operate continuously after they have been
triggered, even with a momentary contact. This option is set by DIP switch 1 (Refer to table 2 for DIP switch settings).
Switch Over Option
The A 4573 is equipped with a “switch over” option which switches the unit from the Alert tone to the Evacuation tone
automatically. This can be adjusted from 30 seconds to 270 seconds in 30 second increments or it can be switched off
entirely. This is adjusted by switch 1 (refer to table 1 for selection details).

Voice Over message
The A 4573 has a voice over option which is used to playback a recorded messsage. This is enabled by switching DIP
switch 2 to “ON” (Refer to table 2 for DIP Switch settings). Once enabled the recorded message will play twice after four
cycles of the evac tone.
Note: this voice over will only operate when the A 4573 is in evac mode.
To record a message, connect the supplied microphone to the 2 way euro block as shown in gure 1. To start recording,
set DIP switch 8 to “ON” and start talking into the microphone. When nished recording, set the DIP switch back to
‘OFF”.
Adjusting Volume Levels
The output levels for the chime, alert/evac tones and the voice over are all adjustable via trimpots as shown in Fig 1.
Note: The Alert and Evac tones are adjusted using the same trimpot. They cannot be adjusted separately.
Chime Options
There are two contacts available for activating the chime tones, and there are four different chimes available (pre
announcement, Ding Dong, Repeating Bing and Repeating Bong). It is possible to have two different chimes available to
use at the same time, but if the cancel trigger is required then the module is limited to one available chime trigger (Refer
to table 3 for selection details).

Remote Triggering of the tones
It is possible to remotely activate the A 4573 from
the Redback® A 2078B and A 2081 wall plates.
Figures 3 and 4 illustrate the wiring connections
required.
Note: The A 2078B and A 2081 were never
designed to be connected to the A 4573 module.
Hence there is no way to illuminate the switch
lamps which require 24V DC to operate. So no
visual indication of the switches being activated is
possible.
