Microphone Input
The A 4565B has a microphone input on the front of the unit. This microphone can be used for either general paging
or emergency paging. Paging overrides all other functions of the A 4565B. Suitable microphones with the PTT function
include the Altronics C 0334 CB type microphone and the C 0379 desk paging microphone. The connection details are
shown in fig 2.2. To use an unbalanced microphone, short pins 1 and 2 together on the microphone plug. The output
level of the microphone is adjusted via the volume pot on the front of the unit (refer to fig 2.2).
A pre-announcement chime (located in the Chime folder on the SD card) which is available on the microphone input is
activated by DIP switch 5 on the rear of the unit (see section 2.4 for more details).
Evacuation Tone
This tone conforms to Australian Standard 1670.4 and once activated has the second highest priority. This can be
overriden only by the paging microphone.
Alert Tone
The Alert tone once activated can be overridden by the Evac tone or by the paging microphone.
Bell Tone
Included is a unique tone or bell chime for signalling lunch breaks, start of class etc. This can be operated from the front
panel or via contacts on the rear panel for remote activation i.e. by a time clock or remote switch. This can be overriden by
the Alert or Evac tones and by the paging microphone.
BGM and Aux Input
Provisions have been made for a BGM source to be played through the controller. The BGM and Aux inputs are
automatically muted when any other function is operated (see section 2.3 for more details).
