Alarm zone 1...8:
A number of different alarm lines can be amalgamated into an alarm zone.
Generally speaking, you would only allocate alarm lines that are located in the
same general area to an alarm zone.
For example, you could allocate all the alarms in building A to alarm zone 1 and all
the alarms in building B to alarm zone 2. An alarm monitor can then be
programmed to switch the images from alarm zone 1, while a separate alarm
monitor is programmed for the images from alarm zone 2.
