9.12 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. 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 .
System will automatically determine which computer will be the main controller based on the
online availability of the master and slave computers. Automatic redundancy kicks in during
the following circumstances:
1.
Master computer information is not configured in slave computer - If the master
computer’s related information is not configured in the slave computer, the slave
computer will consider the master computer as unavailable. As such, the control of
devices will switch to the slave computer automatically.
2. Master computer not reachable from slave computer - If the master computer’s related
information is configured in the slave computer, but the slave computer is unable to
connect to the master computer, the slave computer will keep attempting to connect for
10 consecutive times. If the slave computer is still unable to connect to the master
computer, the control of devices will switch to the slave computer automatically.
3. Master computer not responding - The slave computer will send “heart beat” messages to
the master computer every second. The master computer will acknowledge each “heart
beat” messages to the slave computer. If the slave computer did not receive 6 continuous
“heart beat” acknowledgements from the master computer, the slave computer will
consider the master computer as unreachable. As such, the control of devices will switch
to the slave computer automatically.
4. Master computer acknowledges “heart beat” message - The slave computer will send the
“heart beat messages” continuously. Once the slave computer receives the “heart beat”
acknowledgement from the master computer, the slave computer will consider the
master computer as being back in operation. As such, the slave computer disconnects all
the devices and requests the master computer to take control of the devices.
