Figure 7.9: Import Confirmation Dialog
Be patient, as it may take a while, and watch for the disk activity to stop. If the data is
imported successfully, a pop-up confirmation message appears. If the data is not imported
successful, a pop-up error message appears. The error message will indicate the likely issue
causing the import to fail.
7.3
System redundancy
The Security Escort system redundancy is operational as long as master and slave controllers
are configured in a network setup. By default, master computer is the one controlling the
devices. If the master computer is unavailable for some reasons, slave computer could take
over the operation (automatically or manually). Once the master computer is back online,
slave computer will hand over the control to the master computer. If both the master and
slave computers are not available, the system is not operational. Devices will take control by
themselves.
Notice!
In the event where the master computer is unavailable and the slave computer takes control
of the devices, alarms will be reported on the slave computer. If the master computer
becomes available again, it will try to take control of the devices.
However, if there are still unacknowledged alarms on the slave computer, the master
computer will not succeed in taking control, as the alarms need to be acknowledged on the
slave computer first. The master computer will try to take control of the devices continuously
until the unacknowledged alarms on the slave computer are acknowledged accordingly.
During the acknowledgement process, the receiver's sounders and red LEDs may not be
turned off properly. You may need to turn these off manually from menu Setup > Receiver
configuration.
There are 2 types of redundancy:
1.
2.

applicable for RS232 connections).

main controller.
