In the example above, Isolators 1 and 2 use only five phone connections each; the last three

outputs of Isolator 1 would be 108, 109, 110 which, although unused, conflict with the first 3

addresses of Isolator 2; similarly with Isolators 2 and 3. Solution: disable the last three

outputs of each isolator.

Disabling phone outputs: (Note 1st and 2nd phones cannot be disabled)

2. Set SW6 to 0

3. Press the Test button briefly and confirm the Status LED flashes (2 sec. duration)

4. If required confirm the output status by following the directions below.

Confirming status of Isolator Outputs

To confirm which phone outputs have been disabled, set SW6 to 0 and SW7 to ‘All OFF’ and

press the Test button; each output will have its status LED flash once in turn except those

outputs which have been disabled. Note it may be necessary to press the Test button a

second time on a live system to ensure that the PCB has been reset.
