Commissioning
Notice!
Power up the Loudspeakers Line Isolator System before powering up the public address/
voice alarm system.
1.
Power up the Loudspeakers Line Isolator System at the mains.
2.
Switch on the backup power supply for the Loudspeakers Line Isolator System.
System initialization will take place automatically. During initialization of the system, the
loop initializing LED (7) will be lit on the front panel of the Master Unit. When this LED
goes out, the system is ready for use (maximum initialization time = 10 seconds).
3.
Switch on the public address/voice alarm system.
4.
Perform a commissioning test (Walk Test) for each loop. See Walk Test, page 48.
Notice!
After power down, the Master Unit must remain off for at least 30 seconds before powering
up again.
Walk Test
When the Master Unit is set to Walk Test mode, the power and signal is fed from one side of
the loop only, enabling an easy check of the system.
During Walk Test mode, the Master Unit will display a continuous loop fault until the loop is
installed correctly. When the loop is installed correctly:
–
the connection fault LED (4) on the rear panel of the Master Unit will switch off within
the fault recovery time.
–
The loop OK LED (3) on the rear panel of the Master Unit will light up immediately.
Walk test procedure
1.
Make sure the Master Unit is switched on.
2.
Set the loop to Walk Test mode, by setting the Walk Test DIP switch (5) on the Master
Unit to on.
3.
Route audio to the loop.
4.
Check each loudspeaker for output.
–
Alternatively measure the pilot tone with a measurement device (applicable if pilot
tone is present in the system, and the pilot tone filter is not being used).
–
Alternatively use the test button (3) on the Isolator Board to confirm the power to
each connected loudspeaker.
5.
Check the loop OK LED (3) on the rear panel of the Master Unit. If the loop OK LED is on,
the connection is correct.
6.
Set the Walk Test mode to off.
For problem solving during the Walk Test, refer to Troubleshooting, page 49.
