Introduction
Sentinel SM1 System Monitor provides a complete system wide fault monitoring and reporting solution for mission-critical applications. Built on a tried and trusted
processing “Engine”, Sentinel keeps a watchful eye on the audio system, and if required, any controlling PCs. Problems are reported both via relay contacts to the main
monitoring panel in your system as well as being shown on Sentinel’s front panel display, and buzzers. Multiple Sentinels can even monitor each other and the same
network simultaneously for systems that require dual redundant monitoring.
The Sentinel SM1 System Monitor is a pivotal VNET network accessory, assuring system integrity in sensitiveapplications demanding dependability and requiring
demonstrable functionality. The SM1 checks the status of all devices on the same VNET network, looking for any defects, or lack of performance which may require
attention. The SM1 may be used stand-alone, or with the PodWare software application. Any defects found in the system give rise to clear indication on the indicators
on the front panel, supplementary information being given on the backlit LCD so that the problem can be quickly located and diagnosed. A Comprehensive set of relay
contacts allow defects to be reported to another monitoring system such as a  re panel.
The companion PodWare PC Windows application uses a small panel called a MonIcon to display all the important status information about the SM1 at a glance.
From this small panel it is possible to see the overall system status. The full control panel is only one click away from the MonIcon. From the full control panel, it is very
simple to adjust the  ner details of Sentinel’s operation. In most cases however, there will be no setting up to do.
Sentinel SM1(s) inserted in a VNET network, as illustrated by the diagram below, will monitor each network device for problems, the whole network, and report
“missing” devices including the PC. SM1’s also monitor themselves and problems trigger a network “alarm”, which can be: Normal, Check or Fault.

Product description
Front panel
The Scroll buttons allow to scroll through a number of items on a given page.
The Page buttons allow the view of the display to change; pointing the display (and the encoder where appropriate) at a particular feature or parameter.
Further information can be found in the section Navigating on the Sentinel.
The Encoder (the rotary control knob) allows parameters to be adjusted. Generally, clockwise to increase the value, and counter-clockwise to decrease.
The System Status area on the System Monitor panel indicates the state of the system:
System Normal – Illuminates when no problems are found. This indicator will become dark if any of the following are illuminated: PC Fault, Check System,
System Fault.
PC Online – Illuminates when a controlling computer running the PodWare application is actively connected to this System Monitor
PC Fault – Illuminates when PodWare is not online to the System Monitor; and the unit was set up to expect such a connection.
Check System – Illuminates when one of the monitored devices has detected some anomaly which might require attention, but is not causing any
serious loss of performance.
System Fault – Illuminates when one of the monitored devices has detected a fault which requires the attention of an engineer.
When the unit is starting up, it performs a “Lamp Test” – lighting all the front panel indicators so you can check that they are working. It also performs a Lamp Test
when the unit is discovering devices – warning you that it is not detecting incidents on the network during this process.

BvNet Network
In: For the “Inbound” connection derived from the PC
Link: For connection to other devices
Note that the devices maybe connected in any order. Device will be monitored whether “upstream” or “downstream” from this device.
Misc
In1, In2: Used to feed logic inputs into the device (not currently implemented)
Gnd: Ground, 0v, Earth reference used in conjunction with Logic inputs or Voltage outputs.
RV1, RV2: Voltage outputs for energising external apparatus. +15v is available, and is protected by internal 1000 Ohms of resistance.
System
Check: Three terminals representing a “Check” Incident state. When there is no Check incident, the COM terminal is disconnected from the “Open = ok” terminal,
and connected to the “open=check” terminal. When a Check Incident is present, the COM terminal becomes disconnected from the “open=check” terminal, and
connected to the “Open = ok” terminal. When the device is not powered, the COM terminal is disconnected from the “open=check” terminal, and connected to the
“Open = ok” terminal.
Fault: Three terminals representing a “Fault” Incident state. When there is no Fault incident, the COM terminal is disconnected from the “Open = ok” terminal,
and connected to the “open=fault” terminal. When a Fault Incident is present, the COM terminal becomes disconnected from the “open=fault” terminal, and
connected to the “Open = ok” terminal. When the device is not powered, the COM terminal is disconnected from the “open=fault” terminal, and connected to the
“Open = ok” terminal.
