FRONT PANEL CONTROLS

1 POWER ON/OFF switch

Mains power push button for switching ON and OFF

the internal power supply.

2 OVERLOAD LED

This LED illuminates if the internal power supply has

shut off line power due to overload.

If the internal power supply is overloaded (too many

user stations are connected, or short-circuit in the

interconnecting cables, or thermal overload), it

activates a circuit-breaker which immediately shuts off

line power. This circuit breaker resets automatically

3 seconds after the overload situation is terminated,

restoring line power automatically.

During short-circuit, the LED will flash every 3

seconds. During thermal overload it will remain on

continuously.

The LED will also come on for a few seconds every

time you switch on the mains power.

3 POWER LED

This LED illuminates if line power is supplied by the

internal power supply.

4 BUZZER

This buzzer indicates an incoming our outgoing call.

It is activated by pressing a CALL button of the PS 278

or a CALL button of any other station on channel A or

B for longer than two seconds and the buzzers are not

muted (see 5.7). You can adjust its volume with the

buzzer volume control.

5 BUZZER VOLUME trimmer

6 ALL MIC'S ON/OFF button

With this pushbutton all microphones of the connected

stations can be muted.

7 ALL BUZZERS ON/OFF button

can be muted.

8 AUX VOLUME control knob

This knob adjusts the level of the aux input signal

before it is sent either to the intercom line(s) or to the

headset (see also section 5.8).

9 A/B/HEADSET routing switches

These three switches route the aux input signal to

either:

1) Intercom channel A and/or Intercom channel B

2) Directly to the headset

If the aux is routed to the headset the aux is for local

monitoring only, and can not be routed to the intercom

channels.
