Use Your MegaSys Telenium SNMP Manager to Poll NetGuardian RTUs

How This Application Works:

Equipment Used:

NetGuardian RTUs Telenium Master

In this solution, the DPS Telecom RTU will have the ability to take your environmental alarms and send out SNMP alarms over LAN to your MegaSys Telenium manager. To this end, we have three different RTU options for your project. Please note that there might not be one option that applies to all sites. You might find that the perfect deployment results in some combination of the options.

Option 1 features our smallest unit, the NetGuardian 216. The NetGuardian 216 can monitor 16 contact alarm points and can report SNMP alarms to your Telenium master. The NetGuardian 216 comes with two Analog Ports for real time monitoring of sensors (4-20 mA range) or Battery Plant Monitoring (+/- 92VDC). We included an example of our standard Analog Temperature / Humidity Sensor (with DC-to-DC converter) in the investment section.

Option 2 is the high capacity NetGuardian 480. The NetGuardian 480 is a specialized member of the NetGuardian family in that it can monitor 80 alarm points. This will provide you with the best point-per-price ration available. The NetGuardian 480 will also allow you to operate 4 relays via a remote "Set" command from most SNMP managers.

Option 3 is the NetGuardian 832A G4. It is one of our newest developments in the NetGuardian family, and provides an expandable platform for your discrete alarms. Not only will it monitor 32 discrete alarm points, support 8 controls and 8 relays, it also features 8 analog ports. The NetGuardian G4 features 7 serial reach through ports, a single RS485 port available for Building Access or a GLD Display. The 4-Port HUB will allow you to add Ethernet based equipment to your LAN without the need of purchasing an additional hub.

Lastly, the NetGuardian G4 can be used without an SNMP manager, for it has the ability to send out emails and/or text messages directly to your technicians. Lastly, we included an example of our Analog Temperature/Humidity Sensor, and since the NetGuardian come with a 12V power supply, there is no need to purchase the DC-to-DC converter. Multiple sensors can be powered in this fashion.
