If surveillance is not required press 0 and the display will show Off. This will disable the
associated loudspeaker line faults
If surveillance is required press and release the + key until you have selected the required
frequency and mode.
Note for normal surveillance operation only use 30Hz or 20KHz.

If surveillance is selected, move the cursor along until it flashes beneath the surveillance out
window.
Adjust the level using the + or – keys so that A and B BEL1 return signals =09, this is the typical
return value for a 10 Volt loud speaker line surveillance signal. If you have difficulty in obtaining
a return signal of 09, please check the loudspeaker line
Ambient noise sensor, only available outputs 1-16.

Move the cursor along until it flashes beneath the sensor window, shown above.
If ambient noise sensing is not required or the maximum output is being set, press 0 to disable it.
This will also prevent the associated sensor fault being announced.
When the maximum levels have been set, using the + key slowly increase the value until the
