This Configuration Menu function allows testing of Speakers and Output Amplifiers. This is a critical part of the operation of the ABMA4. Without working speakers, the PSA alerts will not be heard and the unit fail as working intercom.

5. There is a combination of the three above Analysis 1: Tail End Unit Is Not Connected Shown below is an example of how to interpret the graphical interface on a group of ABMA4’s when a TEU is faulty. Figure 17: TEU Fault Example The example above has a cut down view of four ABMA4s and an enlarged PSA Loop Icon for easier readability. -

Note this is the most difficult to detect and analyse as the signal may not reach the end ABMA4 unit. The easiest analysis would involve just a walk down the system cable and a look at each generic display (i.e. wakeup each unit with a menu key press) to work out where the V-Line tick (√) changes to a cross (×). -

ABMA4 unit that has two ticks will have an old confirm time displayed. An alternative method to overcome the problem of the generic screen displaying two ticks is to reset all the ABMA4 along the system cable by turning off the PSA Controller for ten (10) minutes. This will reset all ABMA4s to show PSA Loop with blanks or un-initialized state. -
