Option
Description
SN Poll Timeout
[1] Configures the maximum response time (in milliseconds) for
a SenseNET status query.
Warning: Do not exceed the maximum recommended
settings included in “Configuring the Poll Timeout setting”
on
page 69.
SN+ Looped Bus
[2] Configures the SenseNET+ protocol. If checked, the cluster
uses a Class A closed loop topology.
Leg. Time Sync
[1] Configures the date and time synchronization for legacy
detectors in the network. If checked, the date and time in
legacy detectors is synchronized with the command module.
Note: Date and time synchronization erases any chart
record information stored by the legacy detectors.
2nd Cmd Module
[1] Configures the use of a second command module in a
SenseNET network where redundancy is required. If
checked, the command module acts as the secondary
command module.
See “Using a secondary command module” below for more
information.
[1] Command modules only.
[2] Minimum and standard display modules only.
To configure the network:
1. Select Communications from the Main menu, and then select Network Setup.
2. Enter your configuration changes.
3. Press F1 (Save) to save your changes and exit to the previous screen.
4. If you have no other configuration changes to make, then press F1 (Apply)
from the Main menu or the submenu to apply the changes to the system.
Using a secondary command module
Two command modules can be included in a SenseNET network to provide
redundancy, if required.
The first command module acts as the primary module, controlling and
monitoring the network, while the second command module remains in listening
mode. When the second command module detects that the primary command
module is not operational, it assumes control of the network.
Notes:
• This option only applies to command modules. It must be disabled in the
primary command module and enabled in the secondary command module.
• If the primary command module is recovered, then the secondary module
returns to listening mode.
• The primary command module configures the secondary command module
remotely. It appears in the device list after a network scan.
