Remove the lid from the unit.
3)
Unscrew the small protector plate on the rear panel to reveal the mounting holes for the A 4573.
4)
Line up the A 4573 with the relevant holes in the rear panel, ensure the trimpots on the board are accessible.
5)
Using the screws provided attach the A 4573 mdule to the rear panel via the green euro block.
6)
Plug the 10 way IDC cable to the 10 way header situated inside the Redback® product. (Refer to the instructions
supplied with the Redback® compatible product).
7)
Plug the plastic bushes supplied into the holes on the rear panel through which the trimpots are accessed.

The unit is now ready for operation.
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).
