Using a maintenance network for standalone processors
Although a network interface card (NIC) is not required for standalone processors using relay
output alarm communication, an NIC enables a Silver Network for maintenance purposes.
Installing an NIC and communication wiring between the processor and the central control facility
enables the use of a maintenance computer running Senstar’s Network Manager and Universal
Configuration software. This allows a technician to connect to the OmniTrax processor remotely to
perform maintenance, diagnostic and calibration activities. If an NIC is not installed, the connection
to the UCM must be made at the processor’s location, through the USB port.
NM Mode
The OmniTrax processor can be configured to report alarm and supervision conditions through the
UltraLink modular I/O system. In NM Mode, the UltraLink I/O processor acts as the Network
Manager, providing alarm outputs for a connected network of up to eight Silver devices. In NM
Mode, the Silver devices do not require a connection to a PC running Silver Network Manager
software. Sensor alarms and supervision conditions are assigned to UltraLink I/O outputs (relay or
open collector). When an alarm occurs on a connected sensor, the corresponding UltraLink I/O
output is activated (see NM Mode
on page 249 for additional details).
System power and data configurations
The following methods are available for OmniTrax alarm data communications:
• contact closure alarm output - 4 on-board relays + 8 optional relays via ROC = 10 distinct
alarm zones per processor + tamper and fail (local control mode)
• Network Manager mode - up to 128 outputs available via the UltraLink modular I/O system for
reporting alarm and supervision conditions (plus on-board relays and option card relays)
• Silver Network data - EIA-422 or fiber optic data paths (up to 50 distinct software defined alarm
zones per processor and precise target location)
• Silver Network data - alarm data between processors via the sensor cables, at least one
processor requires a data connection to the NIU (up to 50 distinct software defined alarm
zones per processor and precise target location)
Standalone power/contact closure alarm
A standalone system using local power supplies and contact closure alarm reporting can include a
single processor, or many independent processors. Figure 30:
illustrates three OmniTrax
processors using local power supplies and reporting alarms via contact closure interface.
Note Senstar strongly recommends setting up a maintenance network for
use with the OmniTrax sensor.
Note Connecting two processors to the NIU will provide data redundancy.
Note It is possible to use relay output alarm communications and setup a
Silver Network for maintenance purposes. This enables calibration,
maintenance and diagnostic access to your OmniTrax processors from
a central control facility.
